Connecting the Motor Cable

Connect the motor power cable to the M1, M2, and M3 terminals of the main power connector
and the fourth wire to the PE (Protective Earth) on the heat sink (see diagram above). The
phase connection order is arbitrary because the Composer will establish the proper
commutation automatically during setup.

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 on the Cello.

Be sure that the motor chassis is properly grounded.
