3.8.1.

Connecting Motor Power

Connect the motor power cable to the M1, M2, M3 and PE terminals of the relevant axis. The
phase connection order is arbitrary because the Composer will establish the proper
commutation automatically during setup. If several motor/drive combinations are designed to
operate in an identical manner, it is recommended to download the program into all the drives
and connecting them in the same way.

Notes for connecting the motor cables:

1.

For the greatest 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.

2.

Connect the shield of the cable to the closest ground connection at the motor end.

3.

Be sure that the motor chassis is properly grounded.
