Introduction

Control structure

The SINUMERIK 810/820, Basic Version 3, contains a programmable logic controller (PLC) inthe form of a software PLC without independent hardware (CPU) which is integrated in thecompact CNC control unit. This documentation applies for the T/M versions.

A considerable burden is taken from the PLC user memory by removing standard functionssuch as

• M and S decoding,• organization of the NC-PLC data transfer,• organization of the displaying of error and operational messages

from the PLC user memory and putting them in the system program memory. Additional PLCprograms are no longer required for such auxiliary routines.

This Interface Description covers both signals exchanged between the NC and PLC, andsignals offered by the PLC operating system, e.g. in decoded form.

Note: The * signed signals have to be switched inverse.

Fig. 1.1 shows which modules can be connected to the SINUMERIK 810/820 as I/O devices:

The I/O submodules and the interface submodule for manual encoders (handwheels) areconnected directly to the I/O bus of the SINUMERIK 810/820. It is also possible to connect I/Osubmodules or, in an expansion unit, SINUMERIK 800 and SIMATIC U I/O submodules via themulti-port controller (MPC) interface.

The external machine control panel or customer control panel and the inputs/outputs formachine signals are linked to the PLC via the I/O submodules.

SPINDLE OVERRIDE SWITCH I95.7, I95.6, I95.5, I95.4

The spindle override switch is simulated by the two spindle speed override INCREASE/DECREASE keys on the integrated machine control panel. In input byte 95, the following valueis displayed on the CRT display in percent (Gray code):

PositionCodeD C B A

Correction value in percent

1 0 0 0 1 502 0 0 1 1 553 0 0 1 0 604 0 1 1 0 655 0 1 1 1 706 0 1 0 1 757 0 1 0 0 808 1 1 0 0 859 1 1 0 1 9010 1 1 1 1 9511 1 1 1 0 10012 1 0 1 0 10513 1 0 1 1 11014 1 0 0 1 11515 1 0 0 0 120

Notes:

• The percentage values given in the table are standard values which are stored as machinedata. If necessary, they can be changed. The screen always displays the value defined incorresponding machine data (e.g. it is also possible to set 77% for a ”switch” setting andto display it).

• The codings of the spindle override can be transferred unchanged from input byte 95 tothe PLC/NC interface (QB 100, see Section 4.2.5).

• If both keys (INCREASE/DECREASE) are pressed simultaneously, the override instantlyjumps to the first value (50%).














MODE SELECTOR I95.3, I95.2, I95.1, I95.0

When the MODE selector key of the integrated machine control panel is pressed, the softkeymenu for mode selection is displayed on the CRT. The operating mode can then be selectedby these softkeys:

In input byte 95, the following value is displayed on the CRT display according to the operatingmode selected (Gray Code):

Notes:

• The percentage values given in the table are standard values which are stored as machinedata. If necessary, they can be changed (except code 00001).The CRT always displays the value which has been assigned for the correspondingmachine data (e.g. it is also possible to assign 77% for a ”switch” setting and to displaythis).

• The codings of the feed override can be transferred unchanged from input byte 98 to thePLC/NC interface (QB 84, see Section 4.2.3).

• If both keys (INCREASE/DECREASE) are pressed simultaneously, the override jumpsimmediately to the first value (0%).

Note:

No decoded signals are available for the 5th axis from the external machine control panel forthe SINUMERIK 810T/M

If required, the necessary signals must be created directly in the PLC user program.Thehandwheel mode is selected directly from the PLC user program.









HANDWHEEL SELECTION 1 (2, 3) I100.m m=4...7, I101.n n=0...7

The axes are assigned to the handwheels by the setting data for axes and the softkey functionand the associated bit is set in input byte 100 (101).

1 signal: Handwheel is to be active in the corresponding axis.0 signal: Handwheel operation for the corresponding axis not selected.

Note:

Only one axis can be active at a time for a handwheel.If a second axis is active for the handwheel, the first axis is automatically deactivated.

Functionality of IB 4

As an option either a second axis selector switch module, a second spindle override switchmodule or a rapid traverse override switch module can be built into the external machinecontrol panels. Because of the size of the machine control panel for the SINUMERIK 810, theswitch module must be attached to the machine. The functionality of IB 4 is defined in PLCMD 2001.1, 2002.1 and NC MD 5004.4.

Note:

• The percentage values given in the table are stored in machine data. The standard settingonly includes the machine data for positions 1 to 4; the remaining machine data can be setas required. It is thus possible to evaluate the codes for positions 5 to 7 that a connectedcoding switch or PLC program supplies.

• The values given in the table are only activated when the machine data ”Rapid traverseoverrride switch exists” (5004.4) is set. If the bit is not set, the value taken for the rapidtraverse override is the position of the feedrate override switch with a limitation of 100%.

• The rapid traverse override switch is not transferred from the system program to thePLC/NC interface, i.e. IB4 must be transferred by a PLC user program from Q85.0 toQ85.2.

DIRECTION KEYS I92.7, I92.6, I93.7, I93.6, I94.7, I94.6, I99.n n=0...7

The signals of the direction keys for axes 1 to 4 are decoded and provided in input byte 99,(for the 5th axis in input byte 94) if the codings of the axis selector are available in input bytes1 and 4. The decoding interprets:

• the axis selectors 1 and 2• the signals of the DIRECTION KEYS 1+, 1-, 2+, 2-

1 signal: The corresponding direction key of the set X, Y, Z, 4th, 5th, 6th or 7th axis ispressed.

0 signal: The corresponding direction key of the set X, Y, Z, 4th, 5th, 6th or 7th axis is notpressed.

Note:

The decoding checks whether illegal key combinations have been set and operated (forinstance a simultaneous pressing of X+ and X- or in the case of two axis selectors:simultaneous pressing of X1+ and X2-). Only permissible bit combinations are prepared ininput bytes 92, 93, 94, 99:

• only axis selector 1 available:in the case of illegal key combinations; IB 99 is reset to zero;

• axis selector 1 and 2 (option) available:the direction keys of axis selector 1 have priority over those of axis selector 2.

3.5 Transfer of machine control panel signals

3.5.1 Transfer of the machine control panel signals to the interface

A system program which runs before the cyclic user program (depending on the machine data2003.3, see Description of the PLC interface control) permits all signals of the integrated orexternal machine control panel to be transferred from the input image to the output image(interface range PLC NC, PLC output signals). The subsequent PLC program musttherefore serve only those signals on the interface which are to be modified in a defined way.

Example:

The ”HANDWHEEL 1 ACTIVE” signal is set by the system program, if the handwheel hasbeen selected for the X axis.

3 active 2 active

QB 109

Byte No. Bit: 2 1 0

1 active

Handwheel

However, if handwheel 2 is to be permanently assigned to the X axis, the ”1 active” bit mustbe reset in a defined way and the ”2 active” bit set depending on the handwheel selection.

The system program transfers the signals marked in the following with ”#” into the outputimage; in the following example the external machine control has been used:

Note:

For the interface signal to be output, the touch sensor must output a signal existing longer than20 ms at the NC input. The touch sensor signal effects the following:

a) Delete distance to go b) The current position of the axis is stored without delay in the buffer and transferred from

there to an R parameter.

The touch sensor is enabled in the NC program by an alpha function. The touch sensors onlyeffect ”Delete distance to go” in the channel for the programmed axes for which they wereenabled. The measurement may only be enabled in one channel at a time.

Application example:

To check whether the touch sensor is in reset state before starting the measuring process.

• Automatic measurement of the workpiece produced.• Measurement of the tool.

BATTERY FAULT F24.1

After POWER ON, the voltage of the built-in battery is cyclically checked for a permissiblelower limit. This serves to detect in good time a failure of the battery during long NC operationtimes.

1 signal: Battery voltage has fallen below the limit value.0 signal: Battery voltage is above the lower limit.

Note:

Change the battery only when the NC is under power to avoid data loss.

Notes:

• If NC READY 2 changes to ”0”, then:

a) the feed drives and the spindle drive are stopped by active rapid braking (i.e. withmaximum brake current) and

b) all signals which are transmitted from the NC to the PLC are reset to the inactivestate (reset status).

• All commands which have been sent to the NC must be cancelled if NC READY 2 has a0 signal.

• NC READY 2 changes to ”1” after correction of the fault only if the RESET key of theNC is pressed or if the NC is switched off and on again.

• All functions stored in the buffer memory of the NC are cleared.

Stopping occurs only at the end of the next block.

• The following are ineffective with G63:a) Feed override switch.

While G33 (thread cutting) is effective, FEED STOP can be obtained indirectly by removing theSPINDLE ENABLE signal by combining G33 and FEED ENABLE TOTAL.

In the case of G63, the NC reacts directly to the FEED ENABLE TOTAL signal.

1 signal: Actual direction of rotation CW0 signal: Actual direction of rotation CCW

Notes:

• The signal is derived from the rotational direction of the pulse encoder. With the spindle atrest, the signal corresponds to the last direction of rotation.

• If the spindle is not equipped with a pulse encoder, the signal remains undefined.

1 signal: The programmed speed or the calculated speed at v=const. (G96) is too high.0 signal: The programmed speed or the calculated speed at v=const. is below the per-

mitted limits.

Note:

• The calculated speed at v=const. can be limited via G92 S...

• If the programmed speed or the calculated speed at v=const. exceeds preset limits (asmachine data or for the selected gear speed), the value output as setpoint is the speedwhich corresponds to the lowest limit.

• When limit values are checked, SPINDLE OVERRIDE is taken into account.

Note:

If the signal SPINDLE ENABLE is cancelled during spindle positioning (=0) spindle positioningis aborted. If the signal SPINDLE ENABLE =1, spindle positioning does not continue. If M19is given and the spindle is in the stop state (positioning from standstill) the PLC signalSPINDLE ENABLE must be =1. M19 is not executed with SPINDLE ENABLE =0.

Sequence:

1. CHANGE GEAR signal changes from 0 to 1; the set gear speed is output to the interface.

Controlled by the PLC program:

2. Spindle motor decelerates to zero speed. (Reset spindle enable.)3. Motor accelerates to oscillating speed. (Set oscillating speed+spindle enable.)4. Motor rotation is switched from clockwise to counterclockwise direction (oscillation) to

facilitate the engagement of the gear.5. As soon as the gear is engaged, the PLC is informed, e.g. by means of the ”Gear en-

gaged” signal. This signal must be programmed in the user program to reset the CHANGEGEAR signal. The NC detects the end of gear changing when a new gear speed has beenentered in QB 101.

6. The spindle is again enabled by the PLC and the spindle motor accelerates to the newrotational speed of the gear.

Note:

At the end of the gear changing, the CHANGE GEAR signal must be reset by the PLC userprogram .

RESET Q82.6

1 signal: The NC is reset when a positive edge is encountered, the reset states are set(e.g. with G functions)

0 signal: The NC is not reset.

Note:

The RESET signal can originate either from the RESET key or from the PLC program.










KEY-OPERATED SWITCH Q78.6

0 signal: Input via the keyboard of the NC operator panel is disabled according to thepreset machine data.

1 signal: Input via the keyboard of the NC operator panel is enabled.

Note:

The KEY-OPERATED SWITCH signal can originate either from the KEY-OPERATED SWITCHof the machine control panel or from the PLC program.










CYCLE INHIBIT Q78.3

1 signal: All protected cycles (subroutines of the manufacturer) cannot be input,changed, displayed or output.

0 signal: Access to the protected cycles is possible.

Note:

For maintenance purposes, a program should be provided for cancelling cycle inhibit.If the cycle disable is active, program blocks are not displayed in the menu for current valueswhile a drilling cycle is active.














*EMERGENCY STOP Q78.1

The EMERGENCY STOP button is located either on the standard machine control panel or onthe customer operator panel at an easily accessible position. It is designed as a normallyclosed switch whose signal is wired to an input of the PLC input/output submodules.

1 signal: Operational state of the control; EMERGENCY STOP button has not been operated.0 signal: Emergency stop state of the control; EMERGENCY STOP button has been

operated.

Notes:

• 0 signal causes rapid deceleration with maximum brake current of the feed drives and thespindle drive. After a period fixed by machine data has elapsed, the position control loopsare opened and the NC goes into follow-up mode. The actual positional values are thenalso followed-up in the emergency stop state.

• The feed and spindle drive converters should remain under power until completion of thebraking process.

• If the NC was not switched voltage-free in the EMERGENCY STOP state, the axes neednot be resynchronized (reference point approach) after cancelling the EMERGENCY STOPstate.










DATA IN START 1 AND 2 Q78.4, Q78.5

1 signal: Start of data input via the 1st or 2nd universal interface (e.g. NC part programsetc.).

0 signal: No start of data input.

Note:

The DATA IN START signal must exist for at least one PLC scan.

DRF EFFECTIVE Q82.7

1 signal: During the AUT or MDA modes, handwheel operation is effective as well(differential resolver function).

0 signal: No handwheel operation is possible during the AUT or MDA modes.

Note:

In the AUT or MDA modes, a permanent contour offset (corresponding to the smallest inputincrement defined) can be set via 1 to 3 handwheels which are activated, for instance, bymeans of a key-operated switch. The offset is displayed separately and is retained even afterunconditional blocks.










MODES Q82.3, Q82.2, Q82.1, Q82.0

The modes can be specified as follows with the selector on the external machine control panelor the integrated machine control panel.





PositionCodeD C B A

Mode


Note:

The signals of the mode selector, for instance from the integrated machine control panel, arestored in input byte 95. From there, the mode codings can be transferred unmodified to thePLC/NC interface.If required, the modes can also be specified directly by the PLC program.










READ-IN ENABLE Q87.5, Q96.5

AUT/MDA modes:

1 signal: Data transfer for the next block into main memory is enabled.0 signal: Data transfer for the next block into the main memory is disabled.

JOG, INC or AUT mode interrupted:

1 signal: Activation of the auxiliary functions input via the NC operator panel with NCSTART is enabled.

0 signal: Activation of the input auxiliary functions is disabled.

Note:

If execution of the auxiliary function must have been completed before processing the next NCblock (when changing tools for instance), the automatic block change must be prevented bycancellation of READ-IN ENABLE.

DELETE DISTANCE TO GO Q87.3, Q96.3

0/1 changeover: The distances to go (differences between set and actual positions) of allaxes are deleted. Any following error is corrected. If a dwell block is active,it is aborted.

1/0 changeover: No effect.

Notes:

1) The DELETE DISTANCE TO GO signal must exist for at least one PLC scan.2) After DELETE DISTANCE TO GO a program block containing G90 must follow at least for

the deleted axis.3) In the case of the ”TRANSFORMATION IS ACTIVE = 1” function, the distances to go of

the fictitious axes are also deleted.














DELETE NUMBER OF SUBROUTINE PASSES Q87.2, Q96.2

1 signal: The actual number of remaining subroutine passes is deleted.0 signal: No effect.

Notes:

1) By deleting the remaining number of subroutine passes, the NC can be synchronized witha machine position signalled from outside.

2) The subroutine currently running is executed normally up to M17.3) The 1 signal must exist up to the end of the subroutine and must be cancelled with M17.4) To abort the subroutine execution deliberately, it is necessary to program @ 714 (clear

buffer) in the last block before M17.

Notes:

• If the NC program has been stopped, additional auxiliary functions (for example) can beput into memory. They are executed at the next NC START.

• The program is continued from the point of interruption with NC START. If additionalauxiliary functions have been put into memory while a program was interrupted, only theseare effective with the first Start signal. The program is then continued with the second NCStart.

• The NC STOP signal must exist for at least one PLC scan.

Notes:

• The NC START signal must exist for at least one PLC scan.

• The subroutines in channel 2 can be supplied and started only via the PLC (as externaldata). Calling and starting from channel 1 is not possible.










SKIP BLOCK Q83.7, Q92.7

1 signal: The blocks identified with / (slash) in the workpiece program are skipped, i.e. notprocessed.If there is a series of blocks to be skipped, this signal is only effective if it existsbefore decoding of the first block in this series, preferably before NC Start.

0 signal: No effect.If there is a series of blocks to be skipped, they are executed only if the signal iszero before decoding of the first block in this series, preferably before NC Start.

Note:

Since several blocks are decoded in advance (in pure calculation blocks the number isunlimited), the decision as to whether or not a block will be skipped can be made many blocksbefore processing properly. In order to make sure that the blocks to be skipped are in factskipped at the right time, @714 ”STOP DEC” must be programmed before each skippableblock in the NC part program. If there are several skippable blocks in succession, thecommand must be programmed only before the first skippable block.










SINGLE BLOCK Q83.6, Q92.6

1 signal: In the AUT mode the program is executed in single block operation.0 signal: No effect.




Notes:

• If a contour definition is contained in a program block, only one contour element isexecuted with every start in the SINGLE BLOCK mode. If cutter radius compensation hasbeen selected, intermediate blocks are inserted if required.

• If there is a series of G33 blocks, SINGLE BLOCK is only effective if DRY RUN FEED hasbeen selected.

• Calculation blocks are not executed in single block mode.










SINGLE BLOCK DECODING Q83.5, Q92.5

1 signal: In the AUT mode, all program blocks are executed in single block mode.0 signal: No effect.

Note:

In single block mode, normally only those blocks are executed block-by-block which containtraverse movements and/or auxiliary functions. Pure calculation blocks can also be tested insingle block mode using the SINGLE BLOCK DECODING signal..










DRY RUN FEED Q83.4, Q92.4

1 signal: The dry run feed specified by setting data is effective instead of the programmedfeed (with G01, G02, G03). The dry run feed is also effective instead of the feedper revolution and the feed for thread cutting.

0 signal: The programmed feed is effective.If the signal changed to zero within a G33 block, the programmed feedratebecomes effective only at the end of the block.

FEED OVERRIDE Q84.4, Q84.3, Q84.2, Q84.1, Q84.0

The feed override can be specified by means of the selector switch on the external machinecontrol panel or via the integrated machine control panel as follows:

Notes:

The percentage values given in the table are stored as machine data. Only the machine datafor position 1 to 23 are entered as standard; the machine data not assigned can, however, bestored subsequently if required. Thus, it is also possible to evaluate the codes in positions 24to 31 which are supplied by a connected coding switch or PLC program.













RAPID TRAVERSE OVERRIDE EFFECTIVE Q85.5

This signal is only effective if there is a separate rapid traverse override switch, e.g. on thecustomer operator panel.

1 signal: The rapid traverse override set on the customer operator panel is effective;(prerequisite: MD 5004.4=1).

0 signal: The rapid traverse override values set on the customer operator panel are noteffective. An offset value of 100% is preset.


The rapid traverse override switch can be enabled when installing a new NC program, bymeans of the key-operated switch for example, using the RAPID TRAVERSE OVERRIDEEFFECTIVE signal.










RAPID TRAVERSE OVERRIDE Q85.4, Q85.3, Q85.2, Q85.1, Q85.0

The rapid traverse override can be specified by means of the selector switch on the externalcustomer operator panel as follows:

Notes:

• The percentage values given in the table are stored as machine data. Only the machinedata for positions 1 to 4 are standard; the machine data not assigned can be stored at alater time. Thus, it is also possible to evaluate the codes of positions 5 to 7 which aresupplied by a connected coding switch or PLC program.

• The values given in the table are effective only if the ”Rapid traverse override switchavailable” machine data (5004.4) is set.If the bit is not set, rapid traverse override is determined by the setting of the feed overrideswitch, limited to 100%.If the ”Rapid traverse override switch available” machine data is set (bit 5004.4=1), theoutputs Q 85.0...Q 85.4 must be supplied from the PLC user program.

MIRRORING ON SINUMERIK 810 T Q m.7 m=108, 112, 116, 120, 124, 70, 74

The mirroring function is possible in the X and Z axes (provided the Transmit function is notactive) and in the fictitious axes if Transmit has been selected (all combinations). The PLCoutputs for mirroring in the axes involved are not evaluated if Transmit has been selected.For the X axis:

1 signal: Mirroring of - programmed values- tool nose radius compensation- tool length compensation- position of the tool nose

No mirroring of zero offsets.0 signal: Mirroring not effective.

Note:

When mirroring in the X axis, the axis is always mirrored.

FOLLOW-UP OPERATION Q m.6 m=108, 112, 116, 120, 124, 70, 74

1 signal: NC position control loop is open; the drives are controlled by an external setspeed value.

0 signal: Normal state, the NC position control loops are closed.

Notes:

• A 1 signal opens the position control loop if the axis is stopped.• If the axis is moving, a 1 signal causes rapid braking with max. brake current and, after a

time fixed via machine data has elapsed, the opening of the position control loop. Thenonly the actual position value is followed-up.

• There is an axis stop for all axes moving with interpolation, if FOLLOW-UP OPERATION isset for one axis . The axis for which there is no follow-up operation can only be stopped bysetting the command speed value ZERO. The following error of these axes is stilleliminated.

• If FOLLOW-UP OPERATION is specified for an axis moving with interpolation, an NC faultmessage is output. Further execution of the NC program is then no longer possible.

• After cancellation of follow-up operation (0 signal), the axis need not be resynchronized(reference point approach).

• In order to avoid wrong positioning, follow-up operation may be cancelled only when theNC program is in the STOP state if AUT mode has been selected.For continuing the NC program the actual value of the axis must be synchronized withinthe control. This is achieved by NC Stop (Auto interrrupted) and subsequent NC START.

• Follow-up operation is not possible for fictitious axes.













FEED ENABLE Q m.5 m=108, 112, 116, 120, 124, 70, 74

AUT/MDA mode

1 signal: Causes feed enabling of the respective axis.With Transmit, a feed enable is required for all axes concerned.

0 signal: a) Causes feed stop of the respective axis.b) Causes feed stop of all axes moving with interpolation, if the feed

enabling signal is removed for one axis . In this case, all axes are stoppedwithout deviation from the continuous path.Position control is maintained, i.e. the following error is eliminated.

*DECELERATION Q m.4 m=108, 112, 116, 120, 124, 70, 74

Only effective in APPROACH REFERENCE POINT mode:

1/0 changeover: Causes deceleration of the selected axis to an internally settable creep speed(machine data).

0/1 changeover: Causes the zero point of the measuring system to be approached plus (2 mm distance ± reference point offset).

1: Speed of reference point approach2: Creep speed3: Starting point for reference point approach4: Signal for measuring system zero5: *DECELERATION signal6: Operating cam7: Limit switch

Sequence:

The Z axis must be positioned at the starting point, e.g. in negative direction from thereference point. The operator presses direction key Z+ and the axis approaches the referencepoint. As soon as the operating cam passes the limit switch, the *DECELERATION signalchanges from 1 to 0: The axis decelerates to creep speed. As soon as the operating camclears the limit switch, approach to the next measuring system zero mark is initiated when the*DECELERATION signal changes from 0 to 1. As soon as the zero mark signal appears, theaxis homes in to the reference point.




Conditions:

The limit switch issuing the *DECELERATION signal should be a normally-closed switch. If theconnection to the limit switch is interrupted, this is detected and the axis approach prevented.

1: Speed of reference point approach2: Creep speed3: Starting point for reference point approach4: Signal for measuring system zero5: *DECELERATION signal6: Operating cam7: Limit switch8: Machine end, end of traverse path

Sequence 1:

The Z axis is situated at the starting point, e.g. in negative direction from the reference point.The operator presses direction key Z+ which has been defined by machine data as startingkey for the approach to the reference point. The axis approaches the machine end at whichthe reference point is situated. The direction is detected (*DECELERATION signal=1). Assoon as the operating cam passes the limit switch, the *DECELERATION signal changes from1 to 0: the axis decelerates to zero speed and accelerates to creep speed in the oppositedirection. On clearing the limit switch, approach to the next measuring system zero mark isinitiated when the *DECELERATION signal changes from 0 to 1. As soon as the zero marksignal appears, the axis homes into the reference point.





Sequence 2:

If, at the start of the approach to the reference point, the axis is situated between machine endand reference point (*DECELERATION signal = 0) and if key Z+ is then pressed, the Z axisapproaches the reference point at creep speed in the negative direction.

Conditions:

• Due to the special operating cam (length: from machine end to switching point), thisprocedure is only suitable for reference points situated near the machine end.

• The cam may not leave the limit switch from the switching point to the machine end (endof traverse path), i.e. the *DECELERATION signal remains ”0”.

• The limit switch issuing the *DECELERATION signal must be a normally-closed switch. Ifthe connection to the limit switch is interrupted (*DECELERATION signal = 0), the axiscan only accelerate to creep speed.

Note:

The signal has effect on the real axes only.










PARKING AXIS Q m.3 m=108, 112, 116, 120, 124, 70, 74

1 signal: Axis is in parking position.0 signal: No effect.

Notes:

• If an axis is declared as PARKING AXIS, the monitoring of the connection betweenmeasuring sensor and measuring circuit module is switched off.Accordingly there is no alarm if this connection is opened (e.g. to remove the axis, such asa rotary table, from the machine).

• In addition, a PARKING AXIS must be switched to FOLLOW-UP OPERATION to preventthe monitoring functions of the position control (e.g. standstill monitoring) being triggered.

• If the PARKING AXIS signal is removed, the axis must either be resynchronized or theactual value of the current position must be given by means of ”Set actual value”(PRESET).

• The PARKING AXIS function cannot be used for fictitious axes.













CONTROLLER ENABLE Q m.2 m=108, 112, 116, 120, 124, 70, 74

AUT/MDA mode:

1 signal: Causes closing of the position control loop of the respective axis.0 signal: a) Causes opening of the position control loop if the axis is stationary.

b) Causes rapid deceleration if the axis is moving.The drive is stopped with max. brake current and the position control loop isopened after a time set by machine data has elapsed.

c) All axes travelling in interpolation are stopped, if the controller enable iscancelled for one axis . The axes for which CONTROLLER ENABLES are stillvalid can be stopped only by setting the set speed value ZERO. The followingerror of these axes is eliminated. Further execution of the NC program is thenno longer possible since the axes cannot reach their programmed set position(NC block is not executed).

Set-up modes:

1 signal: Enables the control loop for the respective axis.0 signal: a) Opens the position control loop after the period of time of MD 156 if the axis is

stationary.b) Causes rapid deceleration if the axis is travelling.

Notes:

• A following error remaining after rapid deceleration remains stored and is only compen-sated after renewed controller enable.

• If the controller enable is cancelled while the axes are travelling, an NC alarm is output.• During normal operation, the controller enable signals must be available for all axes to be

moved with interpolation.• The CONTROLLER ENABLE signal applies for real axes only.

Sequence:

1) The travel command of the axis (e.g. X-) unclamps the axis and enables the controller.2) Controller enable ends controller disable.3) As soon as the clamp is released, the feed enable signal is output and the axis travels.4) On cancellation of the travel command, the axis stops and is clamped again. The feed

enable signal is cancelled.5) After clamping, the controller enable signal is cancelled; after a deceleration time tw

(machine data), the signal for controller disable is set again.













2ND SOFTWARE LIMIT SWITCH +/- EFFECTIVE Q m.1, Q m.0 m=108, 112, 116, 120, 124, 70, 74

JOG +/- Q m.7, Q m.6 m=109, 113, 117, 121, 125, 71, 75

1 signal: In the set-up modes, the axis is moved in the preset direction.0 signal: No effect.

Notes:

• The axis traversing speed is determined by machine data in accordance with the operatingmode.

• If the ”+” and ”-”-keys of an axis are pressed simultaneously, no traverse command isactivated.

• Up to two axes can be traversed simultaneously; if the direction keys for more than 2 axesare pressed at the same time, the order of pressing decides which keys are effective.













RAPID TRAVERSE OVERRIDE Q m.5 m=109, 113, 117, 121, 125, 71, 75

1 signal: When traversing in the JOG, REPOS set-up modes via JOG +/-, thesimultaneous setting of the RAPID TRAVERSE OVERRIDE signal causes rapidtraverse. If Transmit has been selected, the signal is not evaluated for the realaxes involved.

0 signal: Jogging at the speed set by machine data.










AXIS DISABLE Q m.3 m=109, 113, 117, 121, 125, 71, 75

1 signal: No position setpoint value is output to the respective machine axis (axisdisabled). The position control loop remains closed.

0 signal: Normal state.

Note:

In order to avoid erroneous positioning, AXIS DISABLE may be cancelled only after programend or abortion. If Transmit has been selected, the signal is not evaluated for the real axesinvolved.

SPINDLE ENABLE Q100.7, Q104.7

1 signal: Causes enabling of the spindle drive so that the spindle is accelerated inaccordance with the ramp characteristic.

0 signal: Causes stopping of the spindle and reduction of the spindle speed in accordancewith the ramp characteristic.

Notes:

• If spindle enable is cancelled, the default set speed is ZERO.

• If the spindle is again enabled, the previous set speed is activated.













CONTROLLER ENABLE Q100.6, Q104.6

1 signal: Enables the spindle controller, the position control loop is closed.0 signal: a) Opens the position control loop if the spindle is at rest.

b) With the spindle running, this signal causes rapid deceleration. The spindle isstopped with maximum brake current and the interface for the drive isseparated after a time fixed by machine data has elapsed.

Note:

Cancellation of the controller enabling signal with the spindle running causes an NC alarm tobe output.










PRESET ZERO SETPOINT Q100.5, Q104.5

1 signal: The current speed setpoint is overwritten with ZERO and thus causes decelerationof the spindle in accordance with the ramp characteristic.

0 signal: No effect.

Note:

Normally, the ZERO speed setpoint is automatically set at program end or on program abort. Ifit is suppressed by machine data, then this must be done via the ZERO SETPOINT INPUTsignal in accordance with criteria which must be given in the PLC program.

Note:

If NC machine data 5210.6=1 the normal reset functions (M02,M30, RESET) do not affectthe spindle. In order to reset the spindle the signal SPINDLE RESET must be used by the PLCif no Automatic program is running.










REVERSE M03/M04 Q101.4, Q105.4

1 signal: The setpoint voltage defined for M03/M04 is reversed.0 signal: No reversal.


In the case of mechanical transmissions (e.g. drilling heads) the direction of rotation isreversed mechanically. The correct rotation can be obtained with REVERSE M03/M04.










AUTOMATIC SELECTION OF GEAR SPEED Q101.3, Q105.3

1 signal: This signal must always be set to ”1” statically if ”Automatic selection of gearspeed” is required for the NC program.

0 signal: The set gear speed is not selected automatically.

Note:

If there is a 1 signal, the gear speed is selected automatically by the NC according to the pro-grammed S value provided constant cutting speed (G96) does not apply. The limit speeds ofthe individual gear speeds are preset via machine data and may overlap each other within thechange limits.The aim is to avoid frequent gear changes. This means that the spindle is kept in the samegear speed until the upper or the lower speed limit is reached; only at the limits of thecurrently set gear speed does the NC change gear.

Normally, the limits of gear changing will more or less overlap so that a wide range of spindlespeeds is available in any one gear. (See Section 4.1.4 CHANGE GEAR signal.)

ACTUAL GEAR SPEED Q101.0 to Q101.2, Q105.0 to Q105.2

A wide speed range of the main spindle is obtained by a change-speed gear in the power trainof the motor. The set speed preset via the NC program with the S value is always the speedof the main spindle and not the speed of the motor. Accordingly, the current gear speed mustbe taken into account when calculating the set speed to be output via an S analog word.

The actual gear speed must therefore be output to the NC in the following code:

Gear speed CodeC B A

12345678

0 0 00 0 10 1 00 1 11 0 01 0 11 1 01 1 1





Notes:

• The lowest spindle speed range is assigned to gear speed 1.

• If there are less than 8 speeds, the codings for the gear speed not available must not betransferred to the NC.

• The signals for the actual gear speed are transferred to the NC at the end of a PLC cycleand cause an immediate change of the spindle speed.

SET ROTATION CLOCKWISE Q103.7, Q 107.7

1 signal: PLUS setpoint voltage is output (rotation clockwise).0 signal: MINUS setpoint voltage is output (rotation counterclockwise).

Notes:

• The SET ROTATION CLOCKWISE signal is effective only in conjunction with theOSCILLATION SPEED or ADJUSTING SPEED signals.

• When the spindle is controlled through the NC, i.e. when the spindle speed is given by theNC program or the NC operator panel, the SET ROTATION CLOCKWISE signal is in-effective.













OSCILLATION SPEED Q103.6, Q107.6

Notes:

• The oscillation speed is set via machine data; the SPINDLE OFFSET is not effective.

• The motor speed , not the spindle speed, is preset with the oscillation speed.

• The period t1 and t2 of the respective direction of rotation is given with the SETROTATION CLOCKWISE by the user program in the PLC. On changing the direction ofrotation, the ramp characteristic is ignored.

• If no oscillation is required, the direction of rotation must be preset.

• The oscillation speed is only effective, if the ”PLC spindle control” signal =1.


Gear changing with oscillation of the drive motor in order to facilitate engagement of the gears(see Section 4.1.4, description of CHANGE GEAR signal).














ADJUSTING SPEED Q103.5, Q107.5

The ADJUSTING SPEED signal is effective in all modes.

1 signal: A fixed adjusting speed for the spindle is given.0 signal: No effect.

Notes:

• The adjusting speed, a very low fixed set speed, is preset via machine data; SPINDLEOFFSET is effective.

• With the adjusting speed, the spindle speed is specified, i.e. the current gear speed istaken into account when calculating the speed setpoint for the spindle motor.

• The adjusting speed is only effective, if the ”PLC spindle control” signal =1.


Turn spindle for measuring purposes at very low speed.










SPINDLE POSITIONING Q103.4, Q107.4

1 signal: Positioning of the spindle is started (e.g. for a tool change).0 signal: No effect.

Notes:

• The set spindle position is determined via machine data (4520).• With the spindle running, positioning is carried out without changing the direction of

rotation.• With the spindle not running, positioning is carried out with the least possible rotation.• The spindle rotates the creep speed specified in the machine data (also applies to

M19=option).• Position spindle is only effective, if the ”PLC spindle control” signal =1.


Positioning of the spindle to the tool or tool change position.










RESYNCHRONIZE SPINDLE Q103.3, Q107.3

1 signal: The spindle is resynchronized to the encoder.0 signal: No effect.

Notes:

RESYNCHRONIZE SPINDLE is effective only in conjunction with PLC SPINDLE CONTROL.


Resynchronization of encoder and spindle control, for example when the encoder is changedwith the drilling head.













ACKNOWLEDGE M19 Q103.2, Q107.2

1 signal: Position control for the spindle is cancelled. The signal is effective only if ”M19active” (I114.1) has previously been transferred from NC to PLC and the NCmachine data 5210.4 =1.


Note:

If the ”M19 active” (I114.1) function has been selected, ”ACKNOWLEDGE M19” cancels thespindle position control. The signal must be generated in the PLC program as follows:A I114.1 (M19 active)A I114.1 (Spindle position reached)A ”User signal”=Q 103.2 (acknowledge M19)=Q 103.0 (PLC spindle control)


Positioning of the spindle to the tool change position; tool change can only be programmedwith M06 without M19 if the PLC has been activated as a result of M06 POSITION SPINDLE.










PLC SPINDLE CONTROL Q103.0, Q107.0

1 signal: Enabling of PLC interface signals (SET ROTATION CLOCKWISE, OSCILLATIONSPEED, ADJUSTING SPEED, POSITION SPINDLE, RESYNCHRONIZESPINDLE, ACKNOWLEDGE M19).

0 signal: Spindle control by the NC.

Notes:

If only PLC SPINDLE CONTROL is set, the set rotation is counterclockwise.

If a new S word is transferred from the NC program during PLC SPINDLE CONTROL, it iseffective only after PLC SPINDLE CONTROL has been removed.

Output of auxiliary functions(NC PLC)

Ready signals

Basic signals

The M, S, T, H auxiliary functions are output to the interface together with the respectivemodification signals. The modification signals indicate that the value in the auxiliary functionword is valid. The modification signals apply for one PLC scan. If several auxiliary functions areprogrammed in an NC block, up to three functions are output to the interface at the same timewithin one PLC cycle.

This also applies if 3M functions are programmed in one block. If more than 3 items ofinformation are programmed in one NC block, the output is divided up over up to 3 PLC scans.When all information has been output, the ”Last information” signal is also output.

The auxiliary functions M, S, T and H can be written with extended address. If an auxiliaryfunction has been programmed with extended address, this is also output. The outputsequence is: M word 1, M word 2, M word 3, S, T, H.




Example for the output of several items of information programmed in one NC block:

The following can be determined by means of machine data:

a) Output of information before or at the beginning fo the NC axis movement (NC MD 5003.2).b) Which information is output at block search (NC MD 546*).c) Binary or BCD output of information (PLC MD 2001).

In the case of M functions, decoded signals are output in addition to the words, both in staticand dynamic form .Static signals are set once by the basic program after decoding. The following M functions aredecoded:

Without extended address: M00 - M99With extended address: 32 M functions in accordance with decoding list (DB 80)

If an M function does not come from the range M00 - M99 and is not contained in thedecoding list, then the M word and ”M NOT DECODED” are output.

With M functions, a dynamic bit and a static bit are output in addition to the word.

A static M function is retained by the PLC user until deleted; a dynamic M function is deletedagain automatically by the PLC operating system after one PLC cycle.



4.3.1 Behaviour in different modes

4.3.1 Behaviour in different modes

4.3.1.1 BLOCK SEARCH mode

Three types of auxiliary functions can be selected via NC machine data:

a) during block search, auxiliary functions are neither stored nor output;b) during block search, the programmed auxiliary functions are output immediately with modi-

fication signal;c) during block search, the NC stores each time the last auxiliary function of an address; after

the NC start, these stored auxiliary functions are output together with the relatedmodification signals (see figure: output of M functions).

Up to three M functions are stored and output, provided they were programmed in oneblock (!) and provided there is no M function following this block up to the search block.

After reaching the block selected, auxiliary functions can be stored manually.

4.3.1.2 AUTOMATIC mode

After the decoding of the auxiliary functions in the NC, they are output - together with therelated modification signal - to the interface.

The modification signal only lasts for one PLC cycle. The auxiliary function words are retaineduntil a new block programmed with M, S, T, H, functions is decoded by the NC.

4.3.1.3 JOG, INC, MDA, AUT mode interrupted

M, S, T and H functions can be stored manually. The INPUT key serves to input the new valueof the operating mode. Erroneous values keyed in are deleted by means of the CLEAR key.The auxiliary function is output to the interface with the corresponding modification signal onlywhen NC START is issued (duration: one PLC cycle).

Note:

The modification signals exist for one PLC scan at a time.









M WORD 1, M WORD 2, M WORD 3 NOT DECODED F26.0, F26.1, F26.2

This signal exists together with the associated M modification signal for one PLC scan.

1 signal: M word greater than 99 (ext. addr.=0) and not contained in decoding list.0 signal: M word less than 99 (ext. addr.=0) or contained in decoding list.

STATIC M SIGNALS, CHANNELS 1 AND 2 F28.n, 30.n ... 52.n n=0 ... 7

The static M signal flags are merely set via M functions decoded by the NC. They remain at”1” until they are reset by a command in the PLC user program.

Up to three M signals are set per PLC cycle.










DYNAMIC M SIGNALS, CHANNELS 1 AND 2 F27.n, 29.n ... 51.n n=0.7

The dynamic M signal flags are set by means of decoded M functions in the same way as thestatic M signal flags, but they remain at ”1” for only one PLC scan before being reset by thePLC operating system. Up to three M signals are output per PLC cycle.

For further information on the parameterization of function blocks 61 and

62, please refer to the PLC Programming Guide

4.4.1 Structure with example

Data can be exchanged between PLC and NC via data channels. Two function blocks areavailable in basic program for activating data transfer:

Read NC data (FB 61) and write NC data (FB 62).

The function blocks enter the parameters for data transfer (data type, data source, data target)into an internal interface. The interface is a first-in/first-out (FIFO) register and can hold up to 8jobs. This ensures that, even when there are several jobs, they are executed in the correctsequence.

A job must still be assigned an interface byte showing the status of data transfer (DB36, DW0- DL32 corresponds to 65 interface bytes). Data transfer can be checked and branchesperformed in the user program according to these acknowledgements.

Fig. 4.32 shows the main signal diagrams.

If data transfer is initiated on FB61 at the READ input, for example, the ”DATA TRANSFERASSIGNED” signal is immediately output on the interface. Because this signal exists until theend of data transfer, it can be used among other things for the purposes of read-in disable.When data transfer has ended, the ”DATA TRANSFER ENDED” signal is output. This signal isnot reset until the user cancels the READ signal on the FB.

In order to reduce the load on the PLC program when calling the FB61/62 function blocksmore than one, FB61/FB62 can be called either unconditionally or conditionally.

The advantage of an unconditional block call is that the FB can be initialized simply.

Fig. 4.33 shows the signal diagrams of all signals when a block is called unconditionally.

The FBs can, optionally, also be called conditionally, i.e. processing of the FBs must takeplace only until the job has been transferred to the job buffer (FIFO). This is notified by DATATRANSFER BUSY.

If the function blocks are incorrectly parameterized (e.g. data source unknown in the PLC), thePLC branches into the stop loop. The number of the interface byte and an error ID are storedin accu 2 of the interrupt stack.

The initiation signal must not be reset with the status information in byte 16 DATA TRANSFERENDED.

Fig. 4.35 shows as an example the parameterization of FB61 for reading the ”Machine-specificactual value of axis” for the 3rd axis. (Data type, AXPM). The actual value should be stored inDB150 in data words 10, 11 and 12.

Cam signals

Cam signals are control signals of the NC. They simulate a trip cam of infinite length which isactivated in a defined direction of approach at a defined position (cam position).

The bit in DB 39 assigned to the cam is set when the corresponding cam range is reachedand cancelled when the cam range is left.

Cam pair and cam range

A cam pair consists of a plus cam and a minus cam. The plus cam is assigned to the axisrange greater than its cam position and the minus cam is assigned to the axis range smallerthan its cam position. The axis range assigned to the cam is referred to as the cam range.

Cam parameters

All cam parameters are contained in an R parameter block. The R parameter block is referredto as the cam parameter block and contains the positions of ten cams broken down into fivecam pairs. The cam positions are related to machine zero and are used in the active machinemeasuring system (metric or inch).The cam positions are not checked for maximum positionvalues (maximum traversing range).

The start of the cam parameter block (Rxxx) is defined via DW 5 in DB 39.

4.6 Software cams

If the SW cam option has been activated, DB 39 is set up on starting the PLC (installation ofthe NC).

The cam signals are not processed unless the option has been activated.They are updated inDB 39 of the PLC before the start of a new PLC cycle only if they have changed. The camsignals are output only after referencing of the axes. Axes for which the NC MD 560* bit 4 (nostart disable before reference point approach) has been set are an exception. Cam signals arenot generated until cam parameters and axis assignment and DB 39 have been activated.

Activating the cam parameters

The cam parameters are stored as pairs (positive/negative value) in R parameters. All camparameters together form a parameter block. When the corresponding bits are set in DB 39,parameter pairs, or all of them, are activated for value transfer by the NC.

The NC reads the assigned parameter pairs from the parameter block only if the bit signalchanges to zero and the bit is set to one after a PLC cycle. Also, a valid start number for theR parameter must be entered in DB 39 at the time of the I/O flank so that the beginning of theparameter block is defined in the R parameters.

The values of a cam pair can be declared invalid by not assigning the cam pair to any axis.

tc PLC cycle time.

Axis assignment of cam parameters

The cam values with which the positions of the desired axes are compared are stored in thecam parameter block. The axis/cam pair assignment is made in DB 39 via the appropriate bits.

It is possible to assign more than one cam pair to each axis but it is not allowed to assign thesame cam pair to more than one axis at the same time.

The axis assignments in DB 39 are then transferred to the NC if the axis assignments in DB 39 have changed.




4.6 Software cams

Note:

The software cam function is allowed only for linear axes.

Example:

DB 39:DL DR

DW 1: 0000 0001 0000 0010 i.e. axis 1 with cam 1, axis 2 with cam 2 DW 2: 0000 1100 0000 0000 i.e. axis 3 with cams 3 and 4

What happens in the various modes

Automatic, MDI

Whether in the ”Reset”, ”Program Stop” or ”Program Running” state, the cam signals areprocessed and output when the software cam function has been activated.

JOG, INC, Repos

Whether in the ”Reset” or ”automatic Interrupted” state, the cam signals are processed andoutput when the software cam function has been activated.

PRESET, REF

The software cams are not effective in these modes.

4.7 Display functions

Menu blocks of the system area and the user area can be inserted in the display by using

• an interface (DB 40) in the PLC program or• a softkey function (SK 56).

This interrupts the normal menu structure. No insertions are possible in the setup mode.

Large actual value display

The ”large actual value display” can still be selected from every menu. If a new menu blockwith a new display is activated, the ”large actual value display” disappears again.

It is now possible to insert menus at any time and at any position within

the normal menu tree. Menus which are normally to be found only in the

REPOS mode can for example also be inserted in the AUTO mode. It is

possible to arbitrarily ignore the predefined tree structure and in so

doing it is possible for menus to be selected which normally can only be

accessed via softkey functions. Since the corresponding softkey function

has not been executed, this can result in serious malfunction. The PLC,

the UMS and the NC user programs are responsible for avoiding this. It

is not monitored by the system program.

Teach-In/Play-Back

Deselecting teach-in/play-back, as up to now, results in branching to the initial menu of themode. The menu stack must then be deleted.

Recall

If Recall is initiated in an entry menu (EM), a specified softkey function is not executed.

Recall to initial menu of mode (Shift+Recall)

Shift-Recall is used to branch to the initial menu of the mode. If insertions have been active inthis mode, the menu stack is deleted and the PLC call ”Special Recall” is deselected. ThePLC priority is not affected.

Insertions via PLC

Using the interface (menu control channel and DB 40), the PLC can interrupt the existingstructure of the menu and can itself define a menu. Recall is used in the entry menu (EM) inorder to get back to the exit menu (XM).

4: The user or the PLC program initiates the return jump into the exit menu.













JOB NUMBER DB 40 DW 52

By using the job number the PLC program can select a job from 1 to 14 possible different jobsfor the NC display management. The START = 1 signal transfers the job to the NC. The jobnumbers must be given in the KF number format.

Job number Significance

1 Insert menu of the system area. Additional channel switchover for channel number <> 0 .

2 Insert menu of the user area.Additional channel switchover for channel number<> 0 .

3 Define new exit menu in system area.

4 Define new exit menu in user area.

5 Execute Recall.

6 Call priority for PLC.Possible only before first PLC insertion.

7 Deselect priority and Special Recall.

8 Call Special Recall and priority.Possible only before 1st PLC insertion.

9 Deselect Special Recall, priority remains active.

10 Select: No basic menu after mode change.

11 Deselect: No basic menu after mode change.

12 Error

13 Switchover channel.

14 Initiate Menu Stack Reset.

Significance of job number

1 and 2: If DB40 DR54 contains a value not equal to zero, the preselected channel issubstituted in DR54 and the menu is shown on the screen when these jobs areexecuted. If the channel no. is illegal, the menu is not displayed.

3 and 4: Define new exit menu (XM).The PLC can define any menu as new XM so that after operating the Recall keythe new XM is displayed rather than the old one. If the menu defined by the PLCdoes not exist, dialog text No. 62 ”FY not configured” is displayed.

The PLC can define a new XM even for mixed inserted displays provided thePLC display is the first inserted display.

When creating the PLC program, ensure that manipulations in the exit

menu result in sensible and useful operation. This is not checked by the

NC system program.

5 and 8: Recall/Special RecallThe Recall sequence of functions can be manipulated by the PLC program(Special Recall). When the Recall key is operated, only a signal indicating thatthe Recall key has been operated is transferred to the PLC. The PLC thendefines the ”Recall menu” as new XM. This ”Special Recall” must be selectedbefore the first PLC inserted display. When the sequence of operations has beencompleted, the PLC must again delete its ”Special Recall Request” becauseotherwise the user would be unable to perform a normal recall. A recall to thebasic menu of the mode by using Shift + Recall is, however, still possible. Themenu stack is deleted and ”Special Recall” is deselected, the PLC priority is notaffected. A recall by the PLC is effective even if the PLC display has beensuperimposed by SK or if no PLC display is active.

6 and 8: Request priority (possible only before the first inserted display)If the PLC has requested priority for its menus, the PLC can again superimposeits inserted menu in spite of active softkey display insertions. The priority must,however, be set before the first PLC display, otherwise the PLC receives anegative acknowledgement.

• An inserted PLC menu can be superimposed by a SK menu. If a PLC menuis once again inserted, the SK menu is interrupted and the second PLCmenu is inserted. The sequence can be continued n times.

• A menu displayed by the PLC cannot be overlaid by the NC. If the NCattempts to overlay a PLC menu, dialog text No. 62 ”MB not configured” isoutput.

Reason: Only one XM and one EM are stored for each type of superimposed display.In the event of multiple superimposition, only the EM is overwritten.




10: Request that no basic display appears when the mode is changed.In this way it is possible to avoid that the basic menu is displayed whenever themode is changed. Provided the signal is set when a mode is left and a menu hasbeen inserted via the PLC or by softkey, the current menu (AUTO/ JOG/ REPOS)is stored. If the mode is selected again, this menu is again displayed. No realdisplay insertions are possible in the new mode; if the Recall function is initiatedin the new mode, not the XM but the Recall menu configured in this menu isdisplayed. If the signal is not set, all insertions are deleted when the mode ischanged.

If the mode is changed, the channel number is not stored. This means

that the current channel is selected if the mode is changed back.

13: Channel changeoverThe required channel must have been prepared in DR 54.For value=0 no reaction.For value=1 ... 3 the required channel is selected.For value > 3 the error bit (D51.1) is set.





14: Trigger Menu Stack Reset

The ”Menu Stack Reset” function (simple mode change reset) deletes all displayinsertions (also those by softkey). If any insertions are active in this mode, theprogram branches to the basic menu of this mode, the menu stack is deleted andSpecial Recall and Recall are deselected. The PLC priority remains active. Whenthe mode is changed, the basic menu is again displayed at the first selection. Ifthe ”No basic menu” signal is still active, the last current menu is again selectedat the second selection.

For key codes, please refer to user interface ”Display key code from NC”.










SPEC RCL DB 40 D56.8

For one PLC cycle this signal is a ”1” signal if the PLC has called for ”Special Recall” beforethe first insertion and the RECALL key has been operated.

No branching to the exit menu; the PLC must/can define a new menu.










DISPLAY CHANNEL NUMBER DB 40 DR56

The number of the selected channel is displayed.





Note:

Mode change

Menu insertions with XM and EM are possible only in one mode. The mode of the firstinsertion is stored (no matter whether by softkey or PLC). After a mode change no moreinsertions are possible.

PLC

There are two different ways in which the PLC can carry out insertions:

1. Menu Stack Reset2. The PLC selects ”Priority”. If the first PLC insertion does not take place in the same mode

as the first insertion (softkey or NC), a ”Menu Stack Reset” is initiated. After the return tothe mode of the first insertion, the basic menu is displayed as after Menu Stack Reset.

Recall

A normal recall is carried out in the setup mode. It is always checked whether a menuinsertion is active. If the current mode is not similar to the mode of the first insertion, a normalrecall is initiated.



4.8 Axis duplication

4.8 Axis duplication

The ”Axis duplication” function enables you to machine two workpieces at the same time or touse one part program in one NC channel for complete machining of a workpiece. The partprogram then contains the machining steps for only one workpiece.

Separate tool length compensations are taken into account for each workpiece, i.e. twodifferent tool systems are required.

Fig. 4.63 Example of axis assignment

Part program% 1234G0 X0 Z0 LFG01 X100 F1000 LFZ20 C80

Block preparation Interpolator

Tool system(X and Z axes)

Tool system 2(X2 and Z2 axes)

Independentaxes(C axis)

The two tool systems can be activated via PLC NC interface. Axis duplication can be activatedin the ”Automatic” and ”MDI” modes.

The PLC NC interface signals prepare for axis pairing. Axis duplication is possible in the”Automatic”, ”MDI” and ”Automatic interrupted” modes.

4.8.1 Method of operation

4.8.1.1 PLC NC interface

The PLC signals Q 81.2 and Q 81.3 are used by the PLC program to control the ”Axisduplication” function. The ”Axis duplication” function must have been activated by theSiemens service department. The interface signals have a preparatory effect. It is only afterNC start that the required function is switched on in the ”AUTOMATIC” or ”MDI” mode. Theactivated function remains modal until the next ”Reset” (Reset key or Mode Change Reset).The selected function must not be changed during program processing (alarm message).





4.8.1.2 Mode functionality with active ”Axis duplication” function

4.8.1.2.1 PRESET and reference point approach

PRESET and reference point approach are not different from the functionality without axisduplication.

The axes must therefore be operated individually. If there are no separate travel keys for toolsystem 2, then these keys must be simulated by the PLC program.

4.8.1.2.2 JOG, REPOS and INC without Automatic Interruption and notafter block search

These modes are not different from the functionality without axis duplication. Tool system 1 ortool system 2 must have one signal. This means that the axes must be operated individually. Ifthere are no separate travel keys for tool system 2, the keys must be simulated by the PLCprogram.

4.8.1.2.3 Automatic and MDI

The preselected function is stored at NC Start. Q 81.2 (tool system 1) or Q 81.3 (tool system2) are used for the selection, which must not be changed before the next end of program orRESET. Only the axes of tool system1 may be programmed in the part program. Dependingon the Q 81.2, Q 81.3 signals, tool system 1, tool system 2 or tool system 1+tool system 2are traversed.

The preselected function is modal until the next RESET or end of program. This means thatthe axes can be traversed according to the selected function even with Automatic Interruptedin the JOG.INC mode.





With axis duplication, the axes can be traversed in two different ways after block search orAUTO Interrupted in the REPOS mode:

Case 1: The tool system 1 axis and the tool system 2 axis have an offset of the same size.When the travel key for the tool system 1 axis has been operated, both axes (toolsystem 1, tool system 2) will simultaneously traverse the offset.

Case 2: The tool system 1 axis and tool system 2 axis have offsets of different sizes. A travelkey must be operated for each of the axes in order to travel the offset.

Case 3: At the selection of NC start, the offsets of all axes are traversed simultaneously.

4.8.2 Complete machining (special function)

Apart from the machine data for mirroring the zero offsets (MD 572*.0=1), machine data (MD1096*) for two fictitious reference points are provided for complete machining of a workpiece.For this purpose the difference of the machine data MD 240* (reference point value) and MD1096* must be defined in the PLC as external zero offset. This simulates a fictitious secondreference point for the SINUMERIK control. The following part of the NC program must thenrefer to this fictitious second reference point.

5.1 Handling

The flag fields of the error and operational messages can be used to produce displays on thescreen in the NC/PLC message line.

In the message line, only one error or operational message can be displayed at any one time.Error messages have priority. As long as an unacknowledged error message exists in themessage line, no operational message can be displayed. If there are several messages, theerror message appearing first or the operational message with the lowest number is displayedin the message line.

It is possible to store up to 12 error messages in order of occurrence and to display 10 ofthese messages in a special message display. If there are additional error messages, they aredisplayed in ascending numerical order when the next screen page is displayed.

Texts can be displayed with the error numbers. The ”Start-up Manual” list gives a moredetailed description of the error input.

The length of the texts is limited to 36 characters. The texts are stored either in the UMSsubmodule or in a reserved RAM area. The texts are entered into the control by inserting theUMS submodule or reading in via an RS232 interface in initial clear mode. The identifier for thealarm texts is % PCA.

The PLC user machine data represent a flag area into which a list of machine data stored inthe NC memory is copied when there is a PLC cold restart. This list resides in the same areaas the NC machine data and can also be changed via the operator panel.The user can preset individual bits and words which he scans in his PLC program. It is thuspossible for him to execute, for example, certain program sections in accordance with the flagstate and to preset certain values for execution via machine data words, e.g. lubricationperiods. Similarly as with the NC machine data, it is possible for him to adapt his PLC programoptimally to the machine tool.

The PLC user machine data can be input byte-by-byte (individual bits):

FY 116: z.B.: 1 0 0 1 0 0 1 1FY 119

or word-by-word (machine data words) as fixed-point number without sign (no negativevalues ):

FY 120: e.g.: 65535 (max. value, if all 16 bits=1)FY 135
