System structure

Line Modules are coupled with the various Motor Modules using prefabricated DC busbar sets
with different current ratings.
Control Units, Line Modules and Motor Modules, and other active SINAMICS components
communicate via DRIVE-CLiQ connections. DRIVE-CLiQ is an internal serial interface of the
drive that enables fast and easy configuration of the complete drive configuration with
prefabricated cables in varying lengths.
The Cabinet Applications are delivered in preconfigured transport units with a total length of
up to 2400 mm each.

Basic Line Module

The Basic Line Modules are used to feed the DC link.
The Basic Blank Modules are suitable for applications where no regenerative energy is
produced, or where energy is exchanged between the motoring and generating axes in the
DC link.
Note
You can find a description of the Basic Line Modules in the "SINAMICS S120 Power Units
Chassis Liquid Cooled" Manual, Chapter "Line Modules / Basic Line Modules".
