The installation procedure of the drive begins with the mechanical installation and attachment of the clamping plates. Depending on your installation environment, you may consider which step to perform first. If the installation space is limited, it may be difficult to fasten the clamping plates after the mechanical installation.The next step is to make the cable connections for motor, supply, I/O and control cables.Finally, go through the installation checklist to ensure safe and correct installation.
5
There are three different ways to install the drive mechanically:• The DIN rail is usually the most convenient way and also suitable for
all frame sizes.• Side mounting is done with three holes; one of the bottom holes is
located at the clamping plate.You can find the frame sizes in the ACS150 Technical Catalogue.
• Back mounting is done using a mounting template to mark the holes for the four screws.
• Please make sure that dust from the drilling does not enter the drive during installation.
• The drive must be installed in an upright position.
6
There are two different clamping plates included:• One for the mains and motor cables, which has three clamps for each
cable: the supply cable, the optional braking resistor, and the motor cable, and
• one for the I/O cables, which has two clamps.
7
Start by fastening the supply and motor clamping plate to the bottom of the drive with two screws as illustrated. Fasten the clamps loosely to the clamping plates.
8
Then, fasten the I/O clamping plate to the supply and motor clamping plate.
9
Make sure that the drive is disconnected from the input power during installation. If the drive is already connected to the input power, wait for 5 min after the disconnection.The main steps for making the cable connections are:
1. First, connect the supply cable.2. Then, measuring the insulation resistance level of the input cable,
motor and the motor cable.3. After verifying that the insulation level is sufficient, install the motor
cable, and4. Finally, connect the control cables according to your planned macro
setting.
10
For minimum radio frequency interference1. Ground the cable by twisting the shield in order to keep the length as
short as possible, and2. Ground the other end of the PE conductor under the cable clamp.
11
Every drive has been tested for insulation between the main circuit and the chassis at the factory. Therefore, do not make any voltage withstand or insulation resistance tests such as hi-pot or megger on any part of the drive.Check the insulation of the input cable according to local regulations before connecting to the drive.Check the insulation of the motor and motor cable as follows.
1. First, check that the motor cable is disconnected from the drive output terminals (U2, V2 and W2)
2. Then, measure the insulation resistances of the motor cable and the motor between each phase and the Protective Earth (PE) by using a measuring voltage of 1 kV DC. The insulation resistance must be higher than 1 Mohm.
12
Do not use an asymmetrically constructed motor cable. To minimize radio frequency interference, there are two choices for grounding the motor cable shield.At the motor end of the cable:
• Ground the cable by twisting the shield so that the length of the shield is less than 5 times the diameter.
• Or ground the cable shield 360 degrees at the lead-through of the motor terminal box.
–Use a separate grounding cable if the conductivity of the cable shield is insufficient (smaller than the conductivity of the phase conductor) and there is no symmetrically constructed grounding conductor in the cable.
• 360 degree grounding is required for the brake resistor cable.
13
Here is the I/O diagram of the ABB Standard macro. It provides a general purpose I/O configuration.However, if you plan to use auxiliary voltage of the drive for the control circuit (PNP connected), the Digital input common terminal should be connected to the Auxiliary voltage output common terminal as shown in the diagram.The reference voltage (10 Vdc) is available if an external potentiometer is used.
14
Switch S1 selects voltage (0 (2)...10 V) or current (0 (4)...20 mA) as the signal type for analog input. By default, it is set to the current position.The signal minimum level e.g. 4 mA instead of 0 mA is set into the parameter 13.01.
15
For protection against interference, all analog control cables must be shielded. Use a double-shielded twisted pair cable for analog signals. Employ one individually shielded pair for each signal. Do not use common return for different analog signals. Run analog and digital signals in separate cables.
16
Twist the grounding conductors together in each pair of the analog signal cable, andstrip the outer insulation of the analog signal cable 360 degrees.
17
For analog signal:• First, ground the control cable by fastening the bare shield under the
clamp.• Connect the conductors to the appropriate terminals. • Then, connect the grounding conductor of the used pair in the analog
signal cable to the SCR terminal.For digital signals:
• Connect the conductors of the cable to the appropriate terminals.• Twist the grounding conductors and shields (if any) of the digital signal
cables to a bundle and connect to the SCR terminal.• Then, secure all cables outside the drive mechanically.
18
Check the mechanical and electrical installation of the drive before start-up by going through the installation check list.For more information on input power fuses, tightening torques and motor cable routings, see the Technical Data chapter in your User’s Manual.
