Interconnecting Several Infeed Units In Parallel - Siemens SINAMICS S120 Commissioning Manual

Commissioning
4.4 Creating a project offline in Startdrive
The white area turns dark gray.
As default setting, a DRIVE-CLiQ connection is established between interfaces X100 and
X200.
Result
The infeed unit is inserted and specified.
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.
4.4.5.3

Interconnecting several infeed units in parallel

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. With parallel connection, the parameter display for the actual values changes
only slightly. Suitable "total values" are derived from the individual values of the power units.
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.
Additional information
Further information on rules, requirements, and restrictions for the parallel connection of Line
Modules and Motor Modules can be found in the SINAMICS S120 Function Manual Drive
Functions.
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 this infeed unit (refer to Chapter "Specifying an infeed
unit (Page 89)").
