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.
