Overview of Motor Modules
The Motor Modules in the SINAMICS S system in booksize format are inverters. They make
the energy from the connected motors' DC link available at an adjusted voltage and with
variable frequency. The control information is generated in the Control Unit and distributed to
the individual Motor Modules via DRIVE-CLiQ.
Depending on the type (Single or Double), each Motor Module has one or two DRIVE-CLiQ
interfaces for connecting the motor encoder evaluation (Sensor Modules).
