A Motor Module is a power unit (inverter) that provides the power for the connected motors.

Control Unit via DRIVE-CLiQ. The open-loop and closed-loop control functions for the Motor

Module are stored in the Control Unit.

One motor can be connected to Single Motor Modules and 2 motors can be connected to

Double Motor Modules.
