Danger and warning information

DANGER

Commissioning is absolutely prohibited until it has been completely ensured that the machine, in which the components described here are to be installed, is in full compliance with the provisions of the EC Machinery Directive. Only appropriately qualified personnel may commission SIMOVERT MASTERDRIVES units and motors. This personnel must carefully refer to the technical customer documentation belonging to the product and be knowledgeable and observe the specified information and instructions on the hazard and warning labels. Operation of electrical equipment and motors inevitably involves electrical circuits with dangerous voltages. All work on the electrical system may only be carried-out when the system has been disconnected from the power supply and locked-out so that it cannot be accidently restarted. Dangerous mechanical movement may occur in the system during operation. SIMOVERT MASTERDRIVES drive units with synchronous motors may only be connected to the line supply through residual-current circuit-breakers, if corresponding to EN 50178, Chapter 5.2.11.2, it has been clearly proven that the drive unit is compatible with the residual-current circuit-breaker. SIMOVERT MASTERDRIVES drive units have been designed for operation on low-ohmic grounded line supplies (TN line supplies). For additional information, refer to the appropriate documentation of the drive converter systems.

Preface


WARNING

For 1FW3 motors, voltages are present at the motor terminals when the rotor is rotating (as a result of the permanent magnets). The voltage can be up to 1000 V depending on the particular motor type. The successful and safe operation of this equipment and motors depends on correct transport, proper storage and installation, as well as careful operation and maintenance. The specifications in the Catalogs and quotations also apply to special variants of the devices and motors. In addition to the danger and warning information/instructions in the technical customer documentation supplied, the applicable domestic, local and plant-specific regulations and requirements must be carefully taken into account.

CAUTION

The motors can have surface temperatures of over +100 °C. For this reason, temperature-sensitive parts (cables or electronic components, for example) may not be placed on or attached to the motor. When connecting-up cables, please observe that they – are not damaged – are not subject to tensile stress – cannot be touched by rotating components.

CAUTION

Motors should be connected in accordance with the operating instructions. They must not be connected directly to the three-phase supply because this will damage them. SIMOVERT MASTERDRIVES drive units and synchronous motors are subject, as part of the routine test, to a voltage test in accordance with EN 50178. While the electrical equipment of industrial machines is being subject to a voltage test in accordance with EN60204-1, Section 19.4, all SIMOVERT MASTERDRIVES drive unit connections must be disconnected/withdrawn in order to avoid damaging the SIMOVERT MASTERDRIVES drive units.

Note When operational and installed in dry areas, SIMOVERT MASTERDRIVES units with synchronous motors fulfill the low-voltage directive. In the configurations specified in the associated EC Declaration of Conformity, SIMOVERT MASTERDRIVES units with synchronous motors fulfill the EMC directive.

Preface


ESDS instructions and electromagnetic fields

CAUTION

An electrostatic-sensitive device (ESDS) is an individual component, integrated circuit, or module that can be damaged by electrostatic fields or discharges. ESDS regulations for handling boards and equipment: When handling components that can be destroyed by electrostatic discharge, it must be ensured that personnel, the workstation and packaging are well grounded! Personnel in ESD zones with conductive floors may only touch electronic components if they are – grounded through an ESDS bracelet and – wearing ESDS shoes or ESDS shoe grounding strips. Electronic boards may only be touched when absolutely necessary. Electronic boards may not be brought into contact with plastics and articles of clothing manufactured from man-made fibers. Electronic boards may only be placed on conductive surfaces (table with ESDS surface, conductive ESDS foam rubber, ESDS packing bag, ESDS transport containers). Electronic boards may not be brought close to data terminals, monitors or television sets. Minimum clearance to screens > 10 cm). Measurements may only be carried-out on electronic boards and modules if – the measuring instrument is grounded (e.g. via a protective conductor) or – before making measurements with a potential-free measuring device, the measuring head is briefly discharged (e.g. by touching an unpainted blank piece of metal on the control cabinet).

DANGER

It may be dangerous for people to remain in the immediate proximity of the product – especially for those with pacemakers, implants or similar – due to electric, magnetic and electromagnetic fields (EMF) occurring as a consequence of operation. The machine/system operator and the people present near the product must observe the relevant guidelines and standards! These are, for example, in the European Economic Area (EEA) the Electromagnetic Fields Directive 2004/40/EC and the standards EN 12198-1 to 12198-3 and in the Federal Republic of Germany the Employer's Liability Insurance Association Regulations for the Prevention of Industrial Accidents BGV 11, with the relevant rule BGR 11 "Electromagnetic Fields". Then a risk assessment must be carried out for every workplace, activities for reducing dangers and exposure for people decided upon and implemented, as well as determining and observing exposure and danger areas.

Preface


Information regarding third-party products

NOTICE This document contains recommendations relating to third-party products. This involves third-party products whose fundamental suitability is familiar to us. It goes without saying that equivalent products from other manufacturers may be used. Our recommendations are to be seen as helpful information, not as requirements or regulations. We cannot accept any liability for the quality and properties/features of third-party products.

Environmental compatibility Environmental aspects during development

When selecting supplier parts, environmental compatibility was an essential criteria. Special emphasis was placed on reducing the envelope dimensions, mass and type variety of metal and plastic parts. Effects of paint-wetting impairment substances can be excluded (PWIS test)

Environmental aspects during production Supplier parts and the products are predominantly transported in re-usable packing. Transport for hazardous materials is not required. The packing materials themselves essentially comprises paperboard containers that are in compliance with the Packaging Directive 94/62/EC. Energy consumption during production was optimized. Production has low emission levels.

Environmental aspects for disposal Motors must be disposed of carefully taking into account domestic and local regulations in the normal recycling process or by returning to the manufacturer. The following must be taken into account when disposing of the motor: Oil according to the regulations for disposing of old oil (e.g. gear oil when a gearbox is mounted) Not mixed with solvents, cold cleaning agents of remains of paint Components that are to be recycled should be separated according to: – Electronics scrap (e.g. encoder electronics, sensor modules) – Iron to be recycled – Aluminum – Non-ferrous metal (gearwheels, motor windings)

Preface


Residual risks of power drive systems When carrying out a risk assessment of the machine in accordance with the EU Machinery Directive, the machine manufacturer must consider the following residual risks associated with the control and drive components of a power drive system (PDS). 1. Unintentional movements of driven machine components during commissioning,

operation, maintenance, and repairs caused by, for example: – Hardware defects and/or software errors in the sensors, controllers, actuators, and

Motor description 11.1 Characteristics

Overview Complete torque motors 1FW3 are water-cooled, high-pole (slow running) permanent-magnet synchronous motors with hollow-shaft rotor. The operating characteristics are essentially comparable to those of synchronous motors. The complete torque motor 1FW3 is supplied completely assembled as compact unit. The range includes 3 outer diameters with various shaft lengths. For shaft height 150 and shaft height 200, the stator and rotor have a flange with centering edges and tapped holes at the drive end according to type of construction IM B14 that allow them to be integrated into a machine. For shaft height 280, the flange with centering edge and through holes is designed in accordance with type of construction IM B35. Together with the drive system SIMOVERT MASTERDRIVES MC (motion control) Performance 2, 1FW3 torque motors form a high performance system with a high degree of functionality. The integrated encoder systems for speed and position control can be selected depending on the application.

Converter/inverter The rated motor current is used to select the appropriate converter/inverter for 1FW3 motors (IN). If the full motor stall torque is required, then the converter/inverter must be dimensioned according to the motor stall current (I0). If the motor is temporarily operated at operating points above the S1 characteristic, then the current requirement of the motors at that point must be taken into account and the appropriate converter/inverter selected. The Path Plus engineering tool can provide support for such application, refer to the Chapter "Engineering".

Engineering 22.1 Configuration software

2.1.1 PATH Plus engineering tool Using the PATH Plus engineering program, three-phase variable-frequency drives can be simply and quickly engineered for the SIMOVERT MASTERDRIVES Vector Control and Motion Control series. The program is a powerful engineering tool that supports the user in all of the engineering steps - from the supply to the motor. A menu-prompted program helps you select and dimension frequency converters, system components and the required motor for a particular drive application. Information and instructions that are automatically displayed guarantee error-free design and planning. Entry level personnel are also supported in understanding how to use the program using a comprehensive help system. PATH Plus navigates and guides the design engineer to achieve reliable, reproducible and cost-effective drive engineering. It starts from the mechanical requirements of the driven machine and the drive application itself using a procedure of dialogs that are logical and simple to handle. The technical data of the selected frequency converters and motors, the selected system components and the necessary accessories are described. PATH Plus allows drive to be engineered starting from a load characteristic or from a load duty cycle and allows applications such as the following to be engineered: Traversing and hoisting gears Swiveling gears Spindle drive Axial winders and Crank drives. PATH Plus includes a user-friendly tool to graphically display the following characteristics: Torque, speed, power, current, velocity and acceleration over time, and Torque with respect to speed. Harmonics fed back into the line supply are calculated and graphically displayed. The engineering results can be saved on a data medium, printed-out or copied into other user programs for ongoing processing and editing through the clipboard. PATH Plus is available with German/English user interfaces and screens. The demonstration version of PATH Plus can be downloaded under the following Internet address: http://www.siemens.com/motioncontrol The full version of PATH Plus can be ordered from your local Siemens office under Order No. 6SW1710-0JA00-2FC0.


Engineering 2.2 Procedure when engineering


2.2 Procedure when engineering

Motion Control Servo drives are optimized for motion control applications. They execute linear or rotary movements within a defined movement cycle. All movements should be optimized in terms of time. As a result of these considerations, servo drives must meet the following requirements: High dynamic response, i.e., short rise times Capable of overload, i.e. a high reserve for accelerating Wide control range, i.e. high resolution for precise positioning

General procedure when engineering The function description of the machine provides the basis when engineering the drive application. The definition of the components is based on physical interdependencies and is usually carried-out as follows: Step Description of the engineering activity

1. The type of drive/infeed type is clarified 2. Definition of supplementary conditions and integration into an automation

system

Refer to the following Chapter

3. The load is defined, the max. load torque is calculated, the motor selected 4. Determining the converter/inverter 5. Steps 3 and 4 are repeated for additional axes 6. Calculation of the required DC link power and definition of the drive converter 7. The line-side options (main switch, fuses, line filters, etc.) are selected 8. Specification of the required control performance and selection of the

SIMOVERT MASTERDRIVES MC Control Unit, defining and selecting the component wiring

9. Additional system components are defined and selected 10. The current demand of the 24 V DC supply for the components is calculated

and the power supplies (SITOP devices, control supply modules) specified 11. The components for the connection system are selected

Refer to the converter catalog

12. Design of the components of the drive line-up

Engineering 2.3 Dimensioning


2.3 Dimensioning

2.3.1 1. Clarification of the type of drive The motor is selected on the basis of the required torque, which is defined by the application, e.g. traveling drive, hoisting drive, feed drive or main spindle drive. Gear units to convert motion or to adapt the motor speed and motor torque to the load conditions must also be considered. As well as the load torque, which is determined by the application, the following mechanical data are among those required to calculate the torque to be provided by the motor: Dynamic masses Diameter of the drive wheel Leadscrew pitch, gear ratios Frictional resistance Mechanical efficiency Traversing paths Maximum velocity Maximum acceleration and maximum deceleration Cycle time

2.3.2 2. Definition of supplementary conditions and integration into an automation system

You must decide whether synchronous or induction motors are to be used. Synchronous motors are the best choice if it is important to have low envelope dimensions, low rotor moment of inertia and therefore maximum dynamic response. Induction motors can be used to achieve high maximum speeds in the field weakening range. Induction motors for higher power ratings are also available. You should also specify whether the drives are to be operated as single-axis drives or in a group as multi-axis drives. The following factors are especially important when engineering: The type of line supply, when using specific types of motor and/or line filters on IT line

supply systems (non-grounded systems) The utilization of the motor in accordance with rated values for winding temperature rises

of 60 K or 100 K The ambient temperatures and the installation altitude of the motors and drive

components. Other supplementary conditions apply when integrating the drives into an automation environment such as SIMATIC or SIMOTION.



For motion control and technology functions (e.g. positioning), as well as for synchronous functions, the corresponding automation system, e.g. SIMOTION D, is used. The drives are interfaced to the higher-level automation system via PROFIBUS.

2.3.3 3. Definition of the load, calculation of max. load torque, definition of the motor The motor-specific limiting curves are used as basis when selecting a motor. These define the torque characteristic with respect to speed and take into account the motor limits based on the line supply voltage and the function of the infeed.

[a] MASTERDRIVES MC, VDC link=540V (DC), Vmot=340Vrms

Figure 2-1 Limiting characteristics for synchronous motor 1FW3201-L



The motor is selected based on the load which is specified by the application. Different characteristics must be used for different loads. The following operating scenarios have been defined: Load duty cycles with constant on time Load duty cycles with varying on time Load duty cycle The objective is to identify characteristic torque and speed operating points, on the basis of which the motor can be selected depending on the particular load. Once the operating scenario has been defined and specified, the maximum motor torque is calculated. Generally, the maximum motor torque is required when accelerating. The load torque and the torque required to accelerate the motor are added. The maximum motor torque is then verified using the motor limiting curves. The following criteria must be taken into account when selecting the motor: The dynamic limits must be observed, i.e., all speed-torque points of the load must lie

below the relevant limiting curve. The thermal limits must be observed, i.e. for synchronous motors, the rms motor torque at

the average motor speed resulting from the load duty cycle must lie below the S1 curve (continuous duty).

For synchronous motors it should be observed that the maximum permissible motor torque is reduced at higher speeds as a result of the voltage limiting curve. In addition, a clearance of 10% from the voltage limiting characteristic should be observed to safeguard against voltage fluctuations.

Load duty cycles with constant on time For load duty cycles with constant on time, specific requirements are placed on the torque characteristic as a function of the speed e.g. M = constant, M ~ n2, M ~ n or P = constant. These drives typically operate at a static operating point. Drives such as these are dimensioned for a base load. The base load torque must lie below the S1 curve. In the event of transient overloads (e.g. when accelerating) an overload has to be taken into consideration. For synchronous motors, the peak torque must lie below the voltage limiting characteristic.



[a] MASTERDRIVES MC, VDC link=540V (DC), Vmot=340Vrms AP 1 Operate for e.g. 1 min AP 2 Continuous operation (S1) for x h (with water cooling) AP 3 Continuous operation (S1) for x h (without water cooling)

Figure 2-2 Selecting motors for load examples with constant on time 1FW3201-L

Note Free convection must be possible for operation without water cooling.



Load duty cycles with varying on time As well as continuous duty (S1), standard intermittent duty types (S3) are also defined for load duty cycles with varying on times. This involves operation that comprises a sequence of similar load cycles, each of which comprises a time with constant load and an off period.

Figure 2-3 S1 duty (continuous operation)

Figure 2-4 S3 duty (intermittent operation without influencing starting)

The load torque must lie below the corresponding thermal limiting characteristic of the motor. An overload must be taken into consideration for load duty cycles with varying on times.

Note The following formulas can be used for duty cycles outside the field weakening range. For duty cycles in the field weakening range, the configuration must be executed with the Pfad Plus configuration tool.

Note When the motor is stationary, a holding torque may be required. This holding torque must be taken into consideration at Mrms. The reason could be that self-locking gearboxes are not used.



Load duty cycle A load duty cycle defines the characteristics of the motor speed and the torque with respect to time.

Figure 2-6 Example of a load duty cycle

A load torque is specified for each time period. In addition to the load torque, the average load moment of inertia and motor moment of inertia must be taken into account for acceleration. It may be necessary to take into account a frictional torque that opposes the direction of motion. The gear ratio and gear efficiency must be taken into account when calculating the load and/or accelerating torque to be provided by the motor.

Note The following formulas can be used for duty cycles outside the field weakening range. For duty cycles in the field weakening range, the configuration must be executed with the Pfad Plus configuration tool.

The rms torque Mmot, rms must, for nmot, average, lie below the S1 curve. The maximum torque Mmax is required when the drive is accelerating and for synchronous motors must lie below the voltage limiting curve/Mmax characteristic. In summary, the motor is selected as follows:

Figure 2-7 Selecting motors according to the load duty cycle for motor 1FW3201-L



Motor selection By making the appropriate iterations, a motor can now be selected that precisely fulfills the operating conditions and application. In a second step, a check is made as to whether the thermal limits are maintained. To do this, the motor current at the base load must be calculated. When engineering a drive according to the load duty cycle with a constant on time with overload, the overload current based on the required overload torque must be calculated. The calculation depends on the type of motor used (synchronous motor, induction motor) and the particular application (load duty cycles with constant on time, load duty cycles with varying on time, load duty cycle). Finally, the other characteristics of the motor must be defined. This is realized by appropriately configuring the motor options.




Mechanical properties of the motors 33.1 Cooling

WARNING The equipment must be safely disconnected from the supply before any installation or service work is carried out on cooling circuit components. Only qualified personnel may design, install and commission the cooling circuit.

3.1.1 Cooling circuit The electrochemical processes that take place in a cooling system must be minimized by choosing the right materials. For this reason, mixed installations, i.e. a combination of different materials, such as copper, brass, iron, or halogenated plastic (PVC hoses and seals), should not be used or limited to the absolutely essential minimum. A differentiation is made between 3 different cooling circuits: Closed cooling circuit Semi-open cooling circuit Open cooling circuit

Table 3- 1 Description of the various cooling circuits

Definition Description Closed cooling circuit The pressure equalizing tank is closed (oxygen cannot enter the system)

and has a pressure relief valve. The coolant is only routed in the motors and converters as well as the components required to dissipate heat.

Semi-open cooling circuit Oxygen can only enter the cooling system through the pressure equalization tank, otherwise the same as "closed cooling circuit".

Open cooling circuit (tower system)

The coolant is cooled in a tower. In this case, there is intensive oxygen contact.

Note Cooling circuits Only closed and semi-open cooling circuits are permissible for motors. Converter systems must be connected before the motors in the cooling circuit.



Figure 3-1 Example of a semi-open cooling circuit

Equipotential bonding All components in the cooling system (motor, heat exchanger, piping system, pump, pressure equalization tank, etc.) must be connected to an equipotential bonding system. This is implemented using a copper bar or finely stranded copper cable with the appropriate cable cross-sections.

NOTICE Under no circumstances may the coolant pipes come into contact with live components. There must always be an isolating clearance of > 13 mm! The pipes must be securely mounted and checked for leaks.

Materials used in the motor cooling circuit The materials used in the cooling circuit must be coordinated with the materials in the motor. Materials used in the motor (cooling jacket material): S355J2+N



Materials and components in the cooling circuit The following table lists a wide variety of materials and components which may or may not be used in a cooling circuit.

Pipes, valves and fittings

Use is not permitted.

PVC Pipes, valves, fittings and hoses

Use is not permitted.

Hoses Reduce the use of hoses to a minimum (device connection). Must not be used as the main pipe for the whole system. Recommendation: EPDM hoses with an electrical resistance > 109 Ω (e.g. Semperflex FKD supplied from Semperit or DEMITTEL; from PE/EPD, supplied from Telle).

Gaskets Pipes, valves and fittings

Use of Viton, AFM34, EPDM is recommended.

Secure with clips conforming to DIN 2817, available e.g. from Telle.

The following recommendation applies in order to achieve an optimum motor heatsink (enclosure) lifetime: Engineer a closed cooling circuit with cooling unit manufactured out of stainless steel that

dissipates the heat through a water-water heat exchanger. All other components such as cooling circuit cables and fittings manufactured out of ABS,

stainless steel or general construction steel.

Note It goes without saying that equivalent products from other manufacturers may be used. Our recommendations should be considered as such. We cannot accept any liability for the quality and properties/features of third-party products.

3.1.2 Engineering the cooling circuit

Pressure The operating pressure must be set according to the flow conditions in the supply and return lines of the cooling circuit. The required coolant flow rate per time unit must be set according to the technical data of the equipment and motors. The maximum permissible pressure with respect to atmosphere in the heat sink and thus in the cooling circuit must not exceed 0.6 MPa (6 bar) If a pump that can achieve a higher pressure is used, suitable measures must be provided on the system side (e.g. safety valve p ≤ 0.6 MPa, pressure control etc.) to ensure that the maximum pressure is not exceeded. The pressure difference between the coolant in the supply and return lines should be selected as low as possible so that pumps with a flat characteristic can be used. An additional flushback filter should be used in the circuit in order to help prevent blockages and corrosion. This allows any material deposits to be flushed out in operation.

Pressure equalization If various components are connected up in the cooling circuit, it may be necessary to provide pressure equalization. Throttle elements must be provided at the coolant discharge of the motor or the particular component.

Avoiding cavitation The pressure drop across a converter or motor must not exceed 0.2 MPa in uninterrupted duty. Otherwise, the high flow rate results in damage due to cavitation and/or abrasion.

Connecting motors in series For the following reasons, connecting motors in series can only be conditionally recommended: The required flow rates of the motors must be approximately the same (< a factor of 2) An increase in the coolant temperature can result in having to derate the second or third

motor if the maximum coolant inlet temperature is exceeded.

Coolant inlet temperature The coolant inlet temperature should be selected so that condensation does not form on the surface of the motor: Tcool > Tambient – 5 K The motors are designed for operation up to a coolant temperature of +30 °C, but still maintaining all of the specified motor data. For another inlet temperature, the continuous torque changes (refer to the table "derating factors").

Table 3- 3 De-rating factors

Coolant inlet temperature ≤ 30 °C 35 °C 40 °C 45 °C Derating factor 1,0 0,97 0,95 0,92

Note Derating is not required for an antifreeze component < 30 % in the coolant (see Chapter "Coolant").

Cooling powers to be dissipated and the cooling flow rate The values specified in the table "Cooling power to be dissipated" refer to a cooling-medium temperature of +30 °C and S1 duty. The cooling power to be dissipated [kW] specified in the table refers to the highest power loss to be dissipated for the particular shaft height.

3.1.3 Coolant

Table 3- 5 Water specifications for coolant

Quality of the water used as coolant for motors with aluminum, stainless steel tubes + cast iron or steel jacket

Chloride ions < 40 ppm, can be achieved by adding deionized water. Sulfate ions < 50 ppm Nitrate ions < 50 ppm pH value 6 ... 9 (for aluminum 6 ... 8) Electrical conductivity < 500 μS/cm Total hardness < 170 ppm

Note It is recommended to use deionized water with reduced conductivity (5 ... 10 µS/cm) (if required, ask the water utility for the values). According to 98/83/EC, drinking water may contain up to 2500 ppm of chloride! Manufacturers of chemical additives can provide support when analyzing the water that is available on the plant side.

Table 3- 6 Coolant quality

Coolant quality Cooling water According to the table "Water specifications for cooling water" Corrosion protection 0.2 to 0.25 % inhibitor, Nalco TRAC100 (previously 0GE056) Anti-freeze protection When required, 20 - 30 % Antifrogen N (from the Clariant Company) Dissolved solids < 340 ppm Size of particles in the coolant < 100 μm

Note The inhibitor is not required if it ensured that the concentration of Antifrogen N is > 20%. Derating is not required for antifreeze protection components < 30 %.



Biocide Closed cooling circuits with soft water are susceptible to microbes. The risk of corrosion caused by microbes is virtually non-existent in chlorinated drinking water systems. Antifrogen N has a biocidal effect even at the minimum required concentration of > 20 %. No strain of bacteria can survive if >20 % Antifrogen N is added. The suitability of a biocide depends on the type of microbe. The following types of microbes are encountered in practice: Slime-forming bacteria Corrosive bacteria Iron-depositing bacteria At least one water analysis per annum is recommended to determine the number of bacterial colonies. Suitable biocides are available from the manufacturer Nalco for example. The manufacturer's recommendations must be followed regarding the concentration and compatibility with any inhibitor used.

NOTICE Biocides and Antifrogen N must not be mixed.

There are other manufacturers of chemical additives in the market. Equivalent products from other manufacturers may be used. The suitability must be checked by testing.

Other coolants (not water-based) When using other coolants (e.g. oil, cooling lubricating medium) de-rating may be required in order that the thermal motor limit is not exceeded. The derating can be determined using the following data at a temperature of 30 °C: Density ρ [kg/m3] Specific thermal capacitance cρ [J/(kg•K)] Thermal conductivity λ [W/(K•m)] Kinematic viscosity ν [m2/s] Flow rate V [rpm]

An inquiry must be set to the manufacturer's plant (Siemens Service Center).

Note The motor power does not have to be reduced for oil-water mixtures with less than 10 % oil.

Service and maintenance It is recommended that the filling level and discoloration or turbidity of the coolant is checked at least once a year. Further, every year it must be checked as to whether the coolant still has the permissible specification. If the coolant level has dropped, the loss should be corrected on closed or semi-open circuits with a prepared mixture of deionized water and inhibitor or Antifrogen N.

3.1.4 Coolant connection The motor is connected to the cooling circuit by means of two female threads on the rear of the motor. The inlet and outlet connections can be freely selected. Recommendation: Inlet at NDE Cooling water connection for 1FW315x and 1FW320x G 1/2" for 1FW328x G 1"

The units should be connected with hoses to provide mechanical decoupling (refer to the table "Materials and components of a cooling circuit").

Mechanical properties of the motors 3.2 Degree of protection


Commissioning When required, before connecting the motors and converters to the cooling circuit, the pipes should be flushed in order to avoid dirt entering the motors and converters. After the units have been installed in the plant, the coolant circuit must be commissioned before the electrical systems.

3.2 Degree of protection The degree of protection designation in accordance with EN 60034-5 (IEC 60034-5) is described using the letters IP and two digits. IP = International Protection 1st digit = protection against ingress of foreign bodies 2nd digit = protection against harmful ingress of water Since coolants used for machine tools and transfer machines usually contain oil, are able to creep, and may also be corrosive, protection against water alone is insufficient. The motors must be protected by suitable covers. Attention must be paid to providing suitable sealing of the motor shaft for the selected degree of protection for the motor. 1FW3 complete torque motors have degree of protection IP54.

Mechanical properties of the motors 3.3 Bearing version


3.3 Bearing version The bearings for the complete torque motors are greased for life and designed for a minimum ambient temperature in operation of -15°C.

Note For bearings without re-lubricating device, we recommend that the bearings are replaced after approx. 20000 operating hours for an ambient temperatures up to a maximum of 40°C, or after 5 years (after delivery) at the latest.

Re-lubricating device (option for 1FW315x and 1FW320x) If required, 1FW3 complete torque motors can be equipped with a re-lubricating device with a lubricating nipple M8 x 1 to DIN 71412-A for the DE and NDE bearings. These measures increase the bearing service life to approx. 40000 h if the re-lubricating intervals are maintained (see the table below) and the ambient temperature does not exceed 40°C. Ordering options: Order code K40 The re-lubricating device cannot be retrofitted!

Note Re-lubricating should be carried out manually using a grease gun (not a hydraulic gun). The grease quantities must be observed. Bearings should be re-lubricated at a low speed if it is not dangerous for persons. The recommended re-lubricating intervals relate to normal loads:• Operation at speeds in accordance with the rating plate data • Precision-balanced operation • Use of specific roller bearing greases

Special versions Unfavorable factors (e.g. effects of mounting/installation, speeds, special modes of operation or high mechanical loads) may require special measures. Contact your local Siemens office, specifying the prevailing general conditions.

Mechanical properties of the motors 3.5 Shaft extension


3.5 Shaft extension The shaft end is implemented as hollow shaft (refer to the dimension drawings). It is available with the following inside diameters: Inside diameter 1FW315x: di = 153 mm Inside diameter 1FW320x: di = 153 mm Inside diameter 1FW328x: di = 250 mm The positive direction of rotation is clockwise when viewing the drive end (flange side).

3.6 Shaft cover If the hollow through-shaft cannot be used by the customer and must be sealed at the NDE for shock protection reasons, the motor can be supplied with a shaft cover at the NDE. Ordering options: Order code T20

3.7 Vibration severity grade The motors conform to vibration severity level A in accordance with EN 60034-14 (IEC 60034-14). The values indicated refer only to the motor. These values can be increased at the motor due to the overall vibration characteristics of the complete system after the drive has been mounted. The vibration severity level is maintained up to the rated speed (nN).

Technical data and characteristics 44.1 Operating range and characteristics

The permissible operating range is limited by thermal, mechanical, and electromagnetic boundaries.

Figure 4-1 Torque characteristics of synchronous motors

Permissible winding temperature range The temperature rise of the motor is caused by the losses generated in the motor (current-dependent losses, no-load losses, friction losses).

Technical data and characteristics 4.2 Voltage limiting characteristics


Torque characteristics of motor The maximum permissible torque depends on the permissible winding overtemperature (100 K) and, in turn, on the mode. To adhere to the temperature limits, the torque must be reduced as the speed increases, starting from static torque M0. The characteristics refer to continuous duty S1 (100 K).

WARNING Continuous duty in the area above the S1 characteristic curve is not thermally permitted for the motor.

The speed range is affected by: The maximum permissible speed (mechanical) nmax mech (centrifugal forces on the rotor,

bearing lifetime), or The maximum permissible speed on the converter nmax Inv (voltage strength of the

converter and/or motor)

4.2 Voltage limiting characteristics

Winding versions A number of winding versions (armature circuit versions) for different rated speeds nN are possible within one motor frame size.

Table 4- 1 Code letter, winding version

Rated speed nN [rpm]

Winding version (10. position of the Order No.)

125 E 200 G 250 H 300 J 400 L 450 M 600 P



Torque limit for operation on converter without field weakening option The voltage induced in the motor winding increases as the speed increases. The difference between the DC link voltage of the converter and the induced motor voltage can be used to apply the current. For converters without field weakening option, this limits the amount of applicable current. This causes the torque to drop off quickly at high speeds. All operating points that can be achieved with the motor lie to the left of the voltage limiting characteristic line. The shape of the voltage limiting characteristic curve is determined by the winding version and the magnitude of the converter output voltage. The characteristic curve is plotted for each winding version in a separate data sheet (see "Technical specifications and characteristics"). The torque-speed diagrams for different converter output voltages are then assigned to each data sheet.

Note The voltage limit characteristic of a motor with 600 rpm rated speed far exceeds that of the same motor type with 200 rpm. For the same torque, however, this motor requires a significantly higher current. For this reason, you should select the rated speed such that it does not lie too far above the maximum speed required for the application. The size (rating) of the converter module (output current) can be minimized in this fashion

Offset of the voltage limit characteristic

NOTICE The offset of the voltage limiting characteristic applies only in the case of approximately linear limiting characteristic curves, e.g. for 1FW3 motors. The voltage limiting characteristic can be offset only if the condition Vmot, new > ViN is fulfilled. Read the induced voltage ViN from the motor rating plate or calculate it: ViN = kE ∙ nN / 1000

In order to identify the limits of the motor for a converter output voltage (Vmot) other than 340 V, the relevant voltage limiting characteristic curve must be shifted (offset) for the particular new output voltage (Vmot new). The degree of offset is obtained as follows: For an output voltage of Vmot, new, an offset is obtained along the X axis (speed) by a factor of:

Vmot, new = new converter output voltage

Vmot = Drive converter output voltage from the characteristic for 340 V



Calculating the new limit torque with the new limiting characteristic

P1 Intersection between voltage limiting characteristic and x axis: Read off or calculate

the speed

P2 Offset from point where the voltage limiting characteristic curve intersects with the x

axis from n1 to n2.

P3 Read-off Mlimit on the voltage limiting characteristic curve specified for Vmot. P4 Calculate Mlimit, new:

The offset voltage limiting characteristic curve is obtained with points P2 and P4. Offset of voltage limiting characteristic from Vmot to Vmot, new

Example of offset of voltage limiting characteristic curve without field weakening Motor 1FW3201-1L; nN = 400 rpm; kE = 519 V/1000 rpm Vmot, new = 290 V; calculated with Vmot = 340 V ViN = kE ∙ nN/1000; ViN = 519 ∙ 400/1000 = 208 V Condition: Vmot, new > ViN is fulfilled.

Enter and connect points P2 and P4. This line is the new voltage limiting characteristic for Vmot, new= 290 V.

Technical data and characteristics 4.3 Tolerance data


4.3 Tolerance data

Tolerance data The data shown in the data sheets are nominal values that are subject to natural scatter.

Table 4- 2 Tolerance data in the motor list data

Motor list data Typ. value Guaranteed value Stall current I0 ± 3 % ± 7,5 % Electrical time constant Tel ± 5 % ± 10 % Torque constant kT ± 3 % ± 7,5 % Voltage constant kE ± 3 % ± 7,5 % Winding resistance Rph ± 5 % ± 10 % Moment of inertia Jmot ± 2 % ± 10 %

Effects of temperature and parameter scatter on the characteristic The torque-speed characteristics specified in the following chapter relate to the nominal values at operating temperature.

NOTICE The motor temperature results in a clear displacement of the voltage limiting characteristic in the upper speed range. This must be taken into consideration during engineering (especially for applications in which the cold motor has to operate at maximum speeds) with converter systems without field weakening.

4.4 Torque-speed characteristics The voltages and currents specified in the data sheets are rms values. Other rated speeds on request.

Note Operation without water cooling Complete torque motors 1FW3 can be operated without water cooling if the torque is appropriately reduced and the thermal losses can be adequately dissipated. The reduction factor depends on the shaft height, length and speed and can be provided when requested.

Motor components 55.1 Thermal motor protection

KTY 84 (PTC thermistor) A temperature-dependent resistor is integrated as temperature sensor to monitor the motor temperature.

Table 5- 1 Properties and technical data

Type KTY 84 (PTC thermistor) Resistance when cold (20 °C) Approx. 580 Ω Resistance when hot (100 °C) Approx. 1000 Ω Response temperature Prewarning: 120 °C ±5° C

Shutdown: 155 °C ±5° C Connection via signal cable

WARNING The polarity must be carefully observed.

The resistance of the KTY 84 thermistor changes proportionally to the winding temperature change (refer to the following Fig.).

Figure 5-1 Resistance characteristic of the KTY 84 as a function of the temperature

The KTY 84 is evaluated in the converter whose closed-loop control takes into account the temperature characteristic of the motor winding. When a fault occurs, an appropriate message is output at the drive converter. When the motor temperature increases, a message "Alarm motor overtemperature" is output; this must be externally evaluated. If this signal is ignored, the drive converter shuts down with the appropriate fault message after a



preset time period or when the motor limiting temperature or the shutdown temperature is exceeded.

CAUTION The integrated temperature sensor KTY protects the complete torque motors against overload conditions: up to 2 • I0 and speed ≠ 0 There is no adequate protection for thermally critical load situations, e.g. a high overload at motor standstill. This is the reason that, for example, a thermal overcurrent relay or a PTC thermistor (optional) must be provided as additional protection. If the maximum overload condition lasts longer than 4 s, then additional motor protection must be provided.

The temperature sensor is designed so that the DIN/EN requirement for "protective separation" is fulfilled.

PTC thermistors (optional) For special applications (e.g. when a load is applied with the motor stationary or for extremely low speeds), the temperature of all of the three motor phases should be additionally monitored using a PTC thermistor triplet. Ordering options: order code A11. The PTC thermistor must be evaluated using an external tripping/evaluation unit (this is not included in the scope of supply). This means that the sensor cable is monitored for wire breakage and short-circuit by this unit. When the response temperature is exceeded, the motor motor must be switched into a no-current condition within 1 s.

5.2 Encoder (option) Speed-controlled operation is possible without any restrictions.

NOTICE Closed-loop position controlled operation is only possible with some restrictions. Please contact your local Siemens office. When the encoder is replaced, the position of the encoder system with respect to the motor EMF must be adjusted. Only qualified personnel may replace an encoder. The encoders are adjusted in the factory for SIEMENS drive converters. Another encoder adjustment may be required when operating the motor with a third-party converter. If the encoder is incorrectly adjusted to the motor EMF, this can result in uncontrolled motion.

The encoder is selected in the motor Order No. (MLFB) using the appropriate letter at the 9th position. With a belt-mounted encoder: 11. position of the Order No. = 7 With coaxial encoder mounting: 11. position of the Order No. = 6

Motor components 5.3 Braking resistors (armature short-circuit braking function)


5.3 Braking resistors (armature short-circuit braking function)

5.3.1 Function description For transistor PWM converters, when the DC link voltage values are exceeded or if the electronics fails, then electrical braking is no longer possible. If the drive which is coasting down, can represent a potential hazard, then the motor can be braked by short-circuiting the armature. Armature short-circuit braking should be initiated at the latest by the limit switch in the traversing range of the feed axis. The friction of the mechanical system and the switching times of the contactors must be taken into account when determining the distance that the feed axis takes to come to a complete stop. In order to avoid mechanical damage, mechanical stops should be located at the end of the absolute traversing range. For servomotors with integrated holding brake, the holding brake can be simultaneously applied to create an additional braking torque – however, with some delay.

CAUTION The converter pulses must first be canceled and this actually implemented before an armature short-circuit contactor is closed or opened. This prevents the contactor contacts from burning and eroding and destroying the converter.

WARNING The drive must always be operationally braked using the setpoint input. For additional information, refer to the Converter Configuration Manual.

The optimum braking torque of the servomotor in regenerative operation can be obtained using armature short-circuit with a matching external resistor circuit. Possible ordering address: http://www.frizlen.com

Note We cannot accept any liability for the quality and properties/features of third-party products.

Rating The ratings of the resistors must match the particular I2t load capability. The resistors can be dimensioned so that a surface temperature of 300° C can occur briefly (max. 500 ms). In order to prevent the resistors from being destroyed, braking from the rated speed can occur max. every 2 minutes. Other braking cycles must be specified when ordering the resistors. The external moment of inertia and the intrinsic motor moment of inertia are decisive when dimensioning these resistors. The kinetic energy must be specified when ordering in order to determine the resistor rating.

Calculating the braking time

NOTICE When determining the run-on distance, the friction (taken into account as allowance in MB) of the mechanical transmission elements and the switching delay times of the contactors must be taken into consideration. In order to prevent mechanical damage, mechanical end stops should be provided at the end of the absolute traversing range of the machine axes.



Figure 5-8 Armature short-circuit braking

5.3.2 Dimensioning of braking resistors The correct dimensioning ensures an optimum braking time. The braking torques which are obtained are also listed in the tables. The data apply for braking from the rated speed. If the motor brakes from another speed, then the braking time cannot be linearly reduced. However, longer braking times cannot occur if the speed at the start of braking is less than the rated speed. The data in the following table is calculated for rated values according to the data sheet. The variance during production as well as iron saturation have not been taken into account here. Higher currents and torques can occur than those calculated as a result of the saturation. The ratings of the resistors must match the particular I2t load capability.

Note The MOTION-CONNECT 500 and MOTION-CONNECT 800 cables are available in a UL version up to a cross-section of 4 x 185 mm2.

6.2 Connecting-up information Pre-assembled cables offer many advantages over cables assembled by customers themselves. In addition to being sure that they will work perfectly and the high quality, there are also cost benefits. Use the power and signal cables from the MOTION CONNECT family. The maximum cable lengths should be carefully observed. Technical data of the cables, refer to Catalog, Chapter "MOTION-CONNECT connection system".

Cable installation Twisted or three-core cables with additional ground conductor should be used for the

motor feeder cables. The insulation should be removed from the ends of the conductors so that the remaining insulation extends up to the cable lug or terminal.

The connecting cables should be freely arranged in the terminal box so that the protective conductor has an overlength and the cable conductor insulation cannot be damaged. Connecting cables should be appropriately strain relieved.

Only remove insulation from the cable ends so that the insulation completely extends up to the cable lug, to the terminal, or end sleeve.

The cable lug size must be adapted to the dimensions of the terminal board connections and the cross section of the line supply cable.

Shielded power and signal cables must be used. Protruding wire ends must be avoided. Take measures to ensure that connecting cables cannot rotate, are not subject to strain

and pushing force and also provide anti-kink protection. It is not permissible to subject cables to continuous force.

Take special care that the required minimum air clearances are actually maintained:



Table 6- 3 Minimum air clearance

Max. terminal voltage < 600 V < 1000 V Minimum air clearance 5.5 mm 8 mm

The screwed electrical connections must be tightened with the specified tightening torques:

Table 6- 4 Tightening torques

Thread Ø M4 M5 M6 M8 M10 M12 M16 Tightening torque (Nm)

0,8 ... 1,2 1,8 ... 2,5 2,7 ... 4 5,5 ... 8 9 ... 13 14 ... 20 27 ... 40

Note In order to avoid disturbing effects (e.g. as a result of EMC), the signal cables must be routed separately away from power cables.

Internal potential bonding (for 1FW315⃞ and 1FW320⃞) The potential bonding between the grounding terminal in the box enclosure and the motor housing is established through the terminal box retaining bolts. The contact locations below the heads of the bolts are bare and are protected against corrosion. The standard screws that are used to connect the terminal box cover to the terminal box are sufficient as potential bonding between the terminal box cover and the terminal box enclosure.

Outer protective conductor or potential bonding conductor (for 1FW328⃞)

Note For shaft height 1FW328⃞, there is an additional connection point on the frame to connect an outer protective conductor or potential bonding conductor. (For shaft height 1FW315⃞ and 1FW320⃞ this is not required.)



Connect-up the ground conductor The grounding conductor cross-section must be compliance with the appropriate installation/erection regulations, e.g. acc. to IEC/EN 60204-1. For shaft height 280, the ground conductor must be additionally connected to the motor frame. A threaded hole is provided for the ground conductor at the designated connection point. This is suitable for connecting stranded conductors with cable lugs or straps with an appropriately terminated conductor end. Please note the following when connecting-up: The connecting surface must be bare and must be protected against corrosion using a

suitable substance, e.g. using acid-free Vaseline Spring washer and normal washer must be located under the head of the screw The minimum screw-in depth and tightening torque of the clamping screw must be

maintained (refer to the Table )

Table 6- 5 Screw-in depth and tightening torque

Screw Minimum screw-in depth Tightening torque M10 x 30 15 mm 28 - 42 Nm

After connecting-up, the following should be checked/tested The inside of the terminal box must be clean and free of any cable pieces All of the terminal screws must be tight The minimum air clearances must be maintained The cable glands must be reliably sealed Unused cable glands must be closed and the plugs must be tightly screwed in place All of the sealing surfaces must be in a perfect condition



Current-carrying capacity for power and signal cables The current-carrying capacity of PVC/PUR-insulated copper cables is specified for routing types B1, B2 and C under continuous operating conditions in the table with reference to an ambient air temperature of 40 °C. For other ambient temperatures, the values must be corrected by the factors from the "Derating factors" table.

7.2 Transport Use suitable load suspension devices when transporting and installing the motor. Country-specific regulations must be observed. If the motor is not to be commissioned immediately following delivery, it must be stored in a dry, dust-free room that is not susceptible to vibration (see Chapter "Storage").

WARNING Hazards when lifting and transporting! Devices and equipment that are badly designed, unsuitable, or damaged can result in personal injury and/or material damage. Lifting devices, industrial trucks, and load suspension devices must comply with requirements. Pay attention to the lifting capacity of the hoisting gear. Do not attach any additional loads. To hoist the motor, use suitable cable-guidance or spreading equipment (particularly if additional components are mounted in or on the motor). After the motor has been placed down, it must be secured so that it cannot roll to the side. The weight of the motor is specified on the rating plate.

CAUTION You must use a cross beam when lifting and transporting the motor using the cable slings provided!

Figure 7-1 Lifting and transporting the motor with a cross beam

Information for using the motors 7.3 Storing


Transporting a motor that has already been in operation If you want to transport a motor that has already been in operation, proceed as follows: 1. Allow the motor to cool down. 2. Remove the connections on the customer side. 3. Empty the motor of any cooling water and purge it carefully with air. 4. Transport and lift the motor using the cable slings and a cross beam.

7.3 Storing

Storing indoors The motors can be stored indoors for up to 2 years without any restrictions on the specified storage time at temperatures of between +5 °C and +40 °C. Apply a preservation agent (e.g. Tectyl) to bare, external components if this has not

already been carried out in the factory. Store the motor in an area that fulfills the following requirements:

– Dry, dust-free, frost-free and vibration-free (vrms < 0.2 mm/s). The relative air humidity should be less than 60%.

– Well ventilated – Offers protection against extreme weather conditions – The air in the storage area must not contain any harmful gases.

Protect the motor against shocks and humidity. Make sure that motor is covered properly. Avoid contact corrosion. You are advised to rotate the end of the shaft manually every

three months.

CAUTION

Bearing damage when the motor is not operational If the motors are stored incorrectly there is a risk of bearing damage such as brinelling, for example as a result of vibration.

Storing the motor after use When you place the motor in storage after use, drain the cooling water ducts and purge them with air so that they are completely empty.

Information for using the motors 7.4 Mounting


7.4 Mounting

7.4.1 Warning and danger information when mounting

DANGER

Torque motors are equipped with strong magnets. This is the reason that when the motors are open there are strong magnetic fields and high magnetic forces of attraction. It is not permissible that personnel with heart pacemakers or metal implants work on an opened motor. Keep clocks/watches and magnetic data mediums (e.g. floppy disks, credit cards, etc.), away from these motors.

WARNING

These motors are electrically operated. When electrical equipment is operated, certain parts of these motors are at hazardous voltage levels. If this motor is not correctly handled/operated, this can result in death or severe bodily injury as well as significant material damage. Please carefully observe the warning information in this chapter and on the product itself.

Only qualified personnel are permitted to carry-out installation/mounting and repair work

on this motor. When transporting, use the cable slings provided All work on the motor should be undertaken with the system in a no-voltage condition The motor should be connected-up according to the circuit diagram provided In the motor terminal box, it must be ensured that the connecting cables are connected

so that there is electrical isolation between the cables and the terminal box cover It must be ensured that the terminal box is sealed It is not permissible to use cables with insulation that is either defective or damaged Only spare parts, certified by the manufacturer, may be used Check that they match the conditions at the installation location (e.g. temperatures,

installation altitude) It is prohibited that the motors are used in hazardous zones and areas Thoroughly remove all anti-corrosion agents from the connecting flange (use

commercially available solvents) The drive-out elements should be rotated by hand. If there is a grinding noise, the cause

must be rectified or the manufacturer contacted.



7.4.2 Overview of the mounting options Torque motors are generally used as direct drives, i.e. without any intermediate gearbox or belts. The principle difference between mounting motors for conventional drives and for direct drives can be seen from the following diagram.

Figure 7-2 Comparison between conventional and direct drive systems



The following must be observed when mounting The torque motors are complete motors equipped with deep-groove ball bearings.

NOTICE Under no circumstances may the max. permissible axial and radial forces be exceeded. Under no circumstances may the bearings of the customer's machine over-determine the motor bearings. If the bearings are over-determined, this can result in immediate bearing damage or the bearing change interval will be significantly reduced.

Figure 7-3 Over-determined bearings of a shaft (to be avoided)



7.4.3 Examples of mounting options

Solution using a coupling Advantage: Simple design, a standard motor can be used Disadvantage: As a result of its function, a coupling must be elastic and therefore has a negative impact on the positive characteristics and features of a directly driven load. The stiffness in the mechanical drive train is reduced.

Figure 7-4 De-coupling the machine shaft from the motor shaft using a coupling



Solution using a torque arm Advantage: Torque arms ensure a torsionally-rigid motor connection in a radial direction and balance axial tolerances and misalignments. This is a highly effective solution for applications with a continuous speed/direction of rotation. Disadvantage: Depending on the version, a torque arm may demonstrate a certain degree of play in a radial direction, which can limit the dynamic response and cause positional errors.

Figure 7-5 De-coupling the stator from the machine base using a torque arm



7.4.4 Mounting the motor frame

Mounting the motor frame to the machine on the customer's side The following possibilities are available for mounting the motor frame of the complete torque motor 1FW3 to the machine on the customer's side:

NOTICE The permissible clamping range must be carefully observed! The permissible surface pressure must not be exceeded!



7.4.5 Mounting and mounting instructions A stable foundation design and precise motor alignment are prerequisites for smooth, vibration-free operation. The following mounting instructions must be carefully observed: Especially for high-speed motors with flange mounting, it is important that the mounting is

stiff in order to locate any resonant frequency as high as possible so that it remains above the maximum rotational frequency.

Thin sheets (shims) can be placed under the motor mounting feet to align the motor and to avoid mechanically stressing the motor. The number of shims used should be kept to a minimum.

In order to securely mount the motors and reliably and safely transfer the drive torque, bolts with strength class 8.8 acc. to ISO 898-1 should be used.

7.4.6 Natural frequency when mounted The motor is an oscillating system with a design-dependent natural frequency, which is higher than the specified maximum speed. When the motor is mounted onto a machine, a new system, which is capable of vibration, is created with modified natural frequencies. These can lie within the motor speed range. This can result in undesirable vibrations in the mechanical drive transmission.

NOTICE Motors must be carefully mounted on adequately stiff foundations or bedplates. Additional elasticities of the foundation/bedplates can cause resonance effects of the natural frequency at the operating speed and, therefore, result in inadmissibly high vibration values.

The magnitude of the natural frequency when the motor is mounted depends on various factors and can be influenced by the following points: Mechanical transmission elements (gearboxes, belts, couplings, pinions, etc.) Stiffness of the machine design to which the motor is mounted Stiffness of the motor in the area around the foot or customer flange Motor weight Machine weight and the weight of the mechanical system in the vicinity of the motor Damping properties of the motor and the driven machine Installation type/position (IM B14, IM V18/19, IM B35) Motor weight distribution, i.e. length, shaft height



7.4.7 Vibration resistance The on-site system vibration behavior depends on factors such as the output elements, mounting situation, alignment, installation, and external vibration and can increase the level of vibration at the motor. Under certain circumstances, the rotor may have to be completely balanced with the output element. To ensure problem-free operation and a long service life, the vibration values specified to ISO 10816 must not be exceeded at the defined measuring points on the motor. Table 7- 3 Max. permissible radial vibration values 1)

Vibration frequency Vibration values < 6.3 Hz Vibration amplitude s ≤ 0.16 mm 6.3 - 250 Hz Vibration velocity vrms ≤ 4.5 mm/s > 250 Hz Vibration acceleration a ≤ 10 m/s2

Table 7- 4 Max. permissible axial vibration values1)

Vibration velocity Vibration acceleration vrms = 4.5 mm/s apeak = 2.25 m/s2

1) Both values must be maintained simultaneously

Figure 7-6 Max. permissible vibration velocity, taking into account the vibration displacement and

vibration acceleration

To measure the vibration velocity, the measuring equipment must fulfill the requirements of ISO 2954. The vibration acceleration must be measured as a peak value in the time range in a frequency band of 10 to 2000 Hz. If appreciable vibration excitation in excess of 2000 Hz (e.g. gear teeth meshing frequencies) can be expected, the measurement range must be adapted accordingly. This does not alter the maximum permissible values.



7.4.8 Clamping systems Various mounting options using clamping elements are shown in this Chapter. We recommend that clamping systems from RINGSPANN GmbH are used. The clamping systems are not included in the scope of supply from Siemens AG.

Information for using the motors 7.5 Commissioning


7.5 Commissioning

7.5.1 Measures before commissioning Before commissioning the system, check that it is properly installed and connected. The drive system must be commissioned as described in the operating instructions for the converter/inverter.

Note This list below does not claim to be complete. It may be necessary to perform additional checks and tests in accordance with the specific situation on-site.

DANGER Risk of electric shock! When commissioning/operating electric motors, parts of the motors are automatically at a dangerous voltage. If this motor is not correctly handled/operated, this can result in death or severe bodily injury as well as significant material damage. All of the warning information on the product must be carefully observed!

CAUTION Thermal hazard due to hot surfaces! The surface temperature of the motors can exceed 100°C. Do not touch hot surfaces. If necessary, implement shock-hazard protection measures. Temperature-sensitive parts (electric cables, electronic components) must not be placed on hot surfaces. Overheating can destroy the windings and bearings and demagnetize the permanent magnets.The motors may only be operated with an effective temperature monitoring function!

WARNING

Danger from rotating rotor! Provide touch protection for output elements!



Mechanical connection All touch protection measures for moving and live parts have been taken. The motor has been correctly mounted, installed and aligned. The rotor can spin without coming into contact with other parts and components. The operating conditions correspond to the data specified on the rating plate. All fixing screws, connecting elements, and electrical connections must be tightened and

properly implemented. Check that the output elements are suitable and appropriately set for the intended

application conditions.

Electrical connection The inside of the terminal box must be clean and free of any cable pieces. All of the terminal screws must be tight. The minimum air clearances must be maintained. The cable glands must be reliably sealed. Unused cable glands must be closed and the plugs must be tightly screwed in place. All of the sealing surfaces must be in a perfect condition.

Monitoring equipment Appropriately configured control and speed monitoring functions ensure that the motor

cannot exceed the permissible speeds specified on the rating plate. Any supplementary motor monitoring devices and equipment have been correctly

connected and are fully functional.

Water cooling If water cooling is used, the cooling water supply must be connected and ready for operation. The cooling water circulation (flow rate, temperature) complies with requirements.

Roller bearings If the motor has been stored under favorable conditions (i.e. in a dry, dust-free room that is not susceptible to vibration) for more than three years, the bearings must be replaced.



7.5.2 Performing a test run

WARNING Water cooling, risk of burns from hot steam If the cooling water supply fails, the motor will overheat. If cooling water runs into the hot motor, hot steam suddenly forms, which escapes under high pressure. The cooling water system can burst. This can result in death, serious injury, or material damage. Do not connect the cooling water supply until the motor has cooled down.

WARNING Danger from rotating rotor Provide touch protection for output elements! Take suitable measures to ensure that feather keys (if used) cannot fall out.

7.5.3 Checking the insulation resistance After long storage or shutdown periods, the insulation resistance of the windings must be measured with respect to ground using a DC voltage.

WARNING Work on power installations must only be carried out by specialists. Before measuring the insulation resistance, read the operating instructions of the insulation measuring equipment you are going to use.

WARNING Dangerous voltage During the measurement as well as immediately after the measurement, the terminals may be at hazardous voltage levels. Touching live components can be result in death or serious injury. Never touch the terminals when measuring or immediately after the measurement. If line supply cables are connected, ensure that the line supply voltage cannot be connected (the line supply voltage must be locked out)

Always measure the insulation resistance of the winding to the motor enclosure when the winding temperature is between 20 and 30°C. When performing the measurement, wait until the final resistance value is reached (this takes approx. one minute).



Limit values The table below specifies the measurement voltage as well as the limit values for the minimum insulation resistance and the critical insulation resistance at a rated motor voltage VN of VN < 2 kV.

Table 7- 5 Stator winding insulation resistance at 25 °C

Rated voltage VN < 2 kV Measurement voltage 500 V (at least 100 V) Minimum insulation resistance with new, cleaned, or repaired windings

10 MΩ

Critical specific insulation resistance after a long operating time 5 MΩ/kV

Note the following: Windings that are essentially like new have an insulation resistance of between

100 ... 2000 MΩ, possible also higher values. If the insulation resistance is close to the minimum value, this could be due to humidity and/or an accumulation of dirt.

The insulation resistance of the motor winding can drop during the course of its service life due to ambient and operational effects. The critical value of the insulation resistance at a winding temperature of 25°C can, depending on the rated voltage, be calculated by multiplying the rated voltage (kV) by the specific, critical resistance value (5 MΩ/kV). Example: Critical resistance for a rated voltage (VN) of 500 V: 500 V x 5 MΩ/kV = 2.5 MΩ

NOTICE

Cleaning and/or drying the windings when reaching critical insulation resistance If the critical insulation resistance is less than or equal to this value, the windings must be dried or, if the rotor is removed, cleaned thoroughly and dried. After drying cleaned windings note that the insulation resistance is lower for a warm winding. The insulation resistance can only be correctly evaluated by performing the measurement on a winding that has cooled down to room temperature (approx. 20 ... 30 °C).

NOTICE

Measured value of the insulation resistance close to the critical value If the measured value is close to the critical value, the insulation resistance should be subsequently frequently checked at short intervals. The values apply for measurements performed at a winding temperature of 25 °C.



7.5.4 Switching on Before you switch on the motor, ensure that the parameters of the frequency converter have been assigned correctly. Use appropriate commissioning tools (e.g. "Drive ES" or "STARTER").

CAUTION Uneven running or abnormal noise The motor can be damaged by improper handling during transport, storage or assembly. If a damaged motor is operated, this can damage the windings or bearings and could even completely destroy the motor. If the motor is not running smoothly or is making abnormal noises, switch it off and determine the cause of the fault as the motor coasts down.

CAUTION Pay attention to the maximum speed The maximum speed nmax is the highest permissible operating speed. The maximum speed is specified on the rating plate. If the speed nmax is exceeded, this can damage the bearings, short-circuit rings, press fits, etc. To ensure that the motor does not run at excessive speeds, the control must be appropriately configured or speed monitoring must be activated in the drive system.

Information for using the motors 7.6 Operation


7.6 Operation The motor must always be connected to the cooling water supply when in operation. When the motor is operated without water cooling, the derating required must be observed (therefore contact you local Siemens office).

CAUTION If the cooling water supply fails or the motor is operated for a short time without cooling water, this can cause it to overheat. This can result in material damage or destroy the motor completely. Never operate the motor without the cooling water supply being switched-in. Monitor the permissible water inlet temperatures.

CAUTION Damage caused by condensation water Condensation can form in the machine as a result of major fluctuations in the ambient temperature, direct solar radiation or a high degree of air humidity. If the stator winding is damp, its insulation resistance decreases. This results in voltage flashovers, which can destroy the winding. Condensation can also cause the inside of the motor to rust.

WARNING Risk of burns from hot steam When cooling water enters the hot motor, this immediately generates hot steam that escapes under high pressure. The cooling water system can burst. This can result in death, serious injury or material damage. Do not connect the cooling water supply until the motor has cooled down.

WARNING Do not remove covers when motor is running Rotating or live parts are dangerous. Death, serious injury or material damage can result if the required covers are removed. All covers that prevent personnel from coming into contact with active or rotating parts, ensure compliance with the required degree of protection, or ensure proper air guidance and, in turn, effective cooling must not be opened/removed during operation.



WARNING Faults in operation Deviations from normal operation (e.g. increased power consumption, temperature or vibration levels, unusual noises or odors, tripping of monitoring devices, etc.) indicate that the machine is not functioning properly. This can cause faults that can result in eventual or immediate death, serious injury or material damage. Immediately inform the maintenance personnel. If in doubt, shut down the motor immediately, taking into account the plant-specific safety regulations.

CAUTION Risk of burns The temperature of certain parts of the motor can exceed 100°C. Physical contact with the machine could cause serious burns. Check the temperature of the parts before touching them and take appropriate protective measures if necessary.

7.6.1 Stoppages

Measures when motors are at standstill and ready for operation Operate the motor regularly, at least once a month, in the event of longer non-operational

periods. Refer to the section "Switching-on" before switching-on the motor to recommission it.

NOTICE

Damage due to improper storage The motor can be damaged if it is not stored properly. If the motor is out of service for extended periods of time, implement suitable anti-corrosion and preservation measures and ensure that the motor is kept dry. When restarting the motor after a long non-operational period, carry out the measures recommended in the Chapter "Commissioning".



7.6.2 Switching off

Measures when switching off When switching off the motor, refer to the operating instructions for the frequency

converter. Switch off the cooling water supply if the motor is not used for longer periods of time.

7.6.3 Faults For changes with respect to normal operation or if faults occur, initially proceed according to the following list. Here, observe the corresponding chapters in the documentation of the components of the complete drive system. Also in test operation, never disable protective functions and devices.

NOTICE Damage to the machine caused by faults Correct the cause of the fault as specified in the remedial measures section. Repair any damage to the machine/motor.

Note When operating the motor with a converter, refer also to the operating instructions of the frequency converter if electrical faults occur.

7.7 Maintenance

7.7.1 Safety information If you are unclear about anything, consult the manufacturer, specifying the motor type and serial number, or arrange for the maintenance work to be carried out by one of the Siemens Service Centers.

DANGER Risk of electric shock when touching live parts Electrical parts and components are at hazardous voltages. Touching these parts will result in an electric shock, which in turn causes death or serious injury. Before starting work on the machines, make sure that the plant or system has been disconnected in a manner that is compliant with the appropriate specifications and regulations. In addition to the main currents, make sure that supplementary and auxiliary circuits, particularly in heating devices, are also disconnected.

WARNING Risk of burns Some parts of the frame of electrical motors can reach temperatures in excess of 100°C. Touching components when the machine is in operation can cause severe burns. Do not touch frame parts while the machine is in operation or immediately after machine operation. Allow parts of the frame to cool down before starting any work.

Safety regulations Before starting any maintenance work, always observe the five safety rules: 1. Disconnect the system 2. Protect against reconnection. 3. Make sure that the equipment is at zero voltage 4. Ground and short-circuit 5. Cover or enclose adjacent components that are still live

Information for using the motors 7.7 Maintenance


7.7.2 Maintenance

NOTICE Only the manufacturer performs service and maintenance work (changing the encoder and the bearings).

7.7.3 Lubrication The bearings for the complete torque motors are greased for life and designed for a minimum ambient temperature in operation of -15°C.

Note For bearings without re-lubricating device, we recommend that the bearings are replaced after approx. 20000 operating hours for an ambient temperatures up to a maximum of 40°C, or after 5 years (after delivery) at the latest.

Re-lubricating device (option for 1FW315x and 1FW320x) These measures increase the bearing service life to approx. 40000 h if the re-lubricating intervals are maintained (see the table below) and the ambient temperature does not exceed 40°C.

Note Re-lubricating should be carried out manually using a grease gun (not a hydraulic gun). The grease quantities must be observed. Bearings should be re-lubricated at a low speed if it is not dangerous for persons. The recommended re-lubricating intervals relate to normal loads:• Operation at speeds in accordance with the rating plate data • Precision-balanced operation • Use of specific roller bearing greases

terms of the quality of dismantling the machine and provision of the components. 2. Follow the five safety rules. 3. Disconnect all electrical connections. 4. Remove all liquids such as oil, water, … 5. Remove all cables. 6. Deatch the machine fixings. 7. Transport the machine to a suitable location for disassembly. Refer also to the information in the section headed "Maintenance".

Dismantling the motor Dismantle the machine using the general procedures commonly used in mechanical engineering.

NOTICE Removing the rotor The rotor in a machine containing permanent magnets must only be removed by the manufacturer. Contact the Siemens Service Center.

WARNING Machine parts can fall The machine is made up of heavy parts. These parts are liable to fall during dismantling. This can result in death, serious injury or material damage. Secure the machine parts being dismantled to prevent them falling.

The motors must be disposed of in accordance with national and local regulations as part of the standard recycling process or they can be returned to the manufacturer.



Demagnetizing permanent magnets Permanent magnets must be demagnetized prior to disposal. This helps avoid potential hazards caused by permanent magnets during and after disposal. Permanent magnets are heated to demagnetize them. Permanent magnets can be demagnetized in one of the following ways: Arrange for the entire machine to be subject to thermal treatment by a specialist disposal

company. Return the machine to the manufacturer who can then remove and demagnetize the rotor

and/or permanent magnets. Rotors that are still installed and have not been demagnetized must not be transported.

NOTICE

Removing the rotor The rotor in a machine containing permanent magnets must only be removed by the manufacturer. Contact the Siemens Service Center.
