Drive system

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". Line Modules can be 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 choice of Line Module is primarily determined by the power
consumption of the motors used. Other important related factors are the line voltage,
regenerative feedback, and the DC-link voltage.
Note
The order designations for the power cables in the figures below do not apply to motors with
single cores.
The following diagram shows an example of a motor integrated into a system with the
connection of Temp-S, Temp-F and an absolute encoder (EnDat with 1 V
