3.5.2. Connecting the Power Cables
The main power connector, which is located on the bottom of the Bassoon, includes the
following pins:

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

3.5.2.1. 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 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.
• The fourth wire should be used for the ground connection between the motor and the
second PE terminal of the Bassoon.
• Be sure that the motor chassis is properly grounded.
