8.1.1 Versions and types
Overview
A Motor Module is a power unit (inverter) that provides energy with an adapted voltage and
variable frequency for the connected motor or motors.
Description
The SINAMICS S220 booksize system is available in 2 versions:
• Precisely 1 motor is connected and operated on a Single Motor Module.
• A Double Motor Module provides 2 independent power supplies for connecting 2 motors.
The Motor Modules are available in 2 types depending on the size and performance:
• C type: Optimized for continuous load with up to 200% overload (continuous motion)
• D type: Optimized for highly dynamic, intermittent duty cycles (discontinuous motion):
– 300% overload for Motor Modules up to 30A
– 200% overload for the Motor Modules 85A, 132A und 200A
The Motor Modules are supplied from the converter DC link.
The control information is generated in the Control Unit and distributed to the individual
Motor Modules via DRIVE-CLiQ. For this reason, the Control Unit contains the open-loop and
closed-loop control functions for the Motor Module.
Depending on the speci󹪝c version, a Motor Module is equipped with one or two DRIVE-CLiQ
interfaces for the encoder evaluation.
