Connecting Infeed Units In Parallel - Siemens SINAMICS S120 Commissioning Manual

Commissioning
5.3 Creating a project offline
The infeed unit is inserted and specified in accordance with your drive configuration.
Note
If an Active Line Module or a Smart Line Module with the chassis format was inserted, then a
Voltage Sensing Module is automatically added and wired.
5.3.5.3

Connecting infeed units in parallel

Overview
In Startdrive, you can interconnect several infeed units (Line Modules) in parallel. During
commissioning, power units connected in parallel are treated like a power unit on the line or
motor side. The parameter view of the actual values changes only slightly when there is a parallel
connection; suitable sum values are formed from the individual values of the power units.
Requirements
• An Active Interface Module (AIM) with integrated line filter is required to operate an Active
Line Module (ALM).
• We recommend external line filters to operate a Basic Line Module (BLM) and a Smart Line
Module (SLM). Line filters can be set via the basic parameterization.
Procedure
To connect infeed units in parallel with modules that have already been added, proceed as
follows:
1. Open "Line Modules" in the hardware catalog.
2. If you have not yet inserted any infeed unit, drag the desired, non-specified infeed unit into
the device view and specify the inserted infeed unit.
