3.4.2 Connecting the Power Cables

The main power connector located at the bottom of the Cello, as follows:

Pin Function

VP+ Pos. Power input

Power return

Protective earth

M1 Motor phase

M2 Motor phase

M3 Motor phase

Note: When connecting several motors, all must be wired in an identical manner.

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.
