2.9 System structure
Line Modules are coupled with the various Motor Modules using prefabricated DC busbar
sets with different current load ratings.
An auxiliary power supply system spanning the individual Cabinet Modules supplies the
required auxiliary voltages for the equipment fans and the 24 V DC loads.
Communication between the Control Unit, Line Module and Motor Module, and other active
SINAMICS components takes place via DRIVE-CLiQ connections.
DRIVE-CLiQ is an internal serial interface of the drive that enables fast and easy
configuration of the complete drive line-up with prefabricated cables in varying lengths.
As an option, Cabinet Modules can be delivered in preconfigured transport units with a total
width of up to 2,400 mm each. This option is recommended in particular for Line Modules
together with Line Connection Modules since, in this case, the Line Connection Module must
be equipped with a pre-charging DC link or line reactors (depending on the type of Line
Module), in addition to the electrical interface (mounted on a busbar).
