Connecting the Motor Cable
Connect the motor power cable to the M3, M2, M1 and the PE (motor chassis) terminals of the
motor connector (see diagram below). The phase connection order is arbitrary because the
Composer will establish the proper commutation automatically during setup. However, if you
are willing to avoid from tuning each drive separately, and you plan to copy this setup file to
other drives – then, the motor-phase order, on all copy drives, must be kept the same as in the
first drive.
Notes for connecting the motor cables:
•
For best immunity, it is highly recommended to use a shielded (not twisted) cable for the
motor connection. A 4-wire shielded cable should be used. The gauge is determined by the
actual current consumption of the motor.
•
Connect the shield of the cable to the closest ground connection at the motor end.
•
Connect the shield of the cable to the PE terminal in the drive’s motor-connector.
•
Be sure that the motor chassis is properly grounded.
•
To close the motor cable into the drive, use the barrel connector, M6 spring washer and
M6 nut (in the drive). The required torque is 3 to 4 Nm.
•
To close the PE wire into the drive, use the barrel connector, M6 flat washer, M6 spring
washer and M6 screw to the heat sink. The required torque is 3 to 4 Nm.
