System requirements 

Components 

The drive system that feeds a motor comprises an infeed module, a power module and a 

control module. For the SINAMICS S120 drive system, these modules are called "Line 

Modules", "Motor Modules" and "Control Units". The Line Module is either regulated with 

feedback (ALM, Active Line Module), unregulated with feedback (SLM, Smart Line Module), 

or unregulated without feedback (BLM, Basic Line Module). 
To operate several motors simultaneously on a single drive system, either one Motor Module 

per motor or one Motor Module for several motors can be provided, depending on the 

application. The appropriate Line Module is determined by the power consumption of the 

motors used. 

 

 

Note 
The order designations for the power cables in the figures below do not apply to motors with 

single cores.
