Connecting the Motor Cable
Connect the motor power cable to the M1, M2, M3 and PE terminals of the main power
connector. The phase connection order is arbitrary because the Composer will establish the
proper commutation automatically during setup. However, if you plan to copy the set-up to
other drives, then the phase order on all copy drives must be the same.
Notes for connecting the motor cables:
For best noise 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.
The fourth wire should be used for the ground connection between the motor and the PE
terminal of the Cornet.
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 on the Cornet.
Be sure that the motor chassis is properly grounded.
