Line Modules Booksize Compact
Frequency with which the DC link is precharged
The frequency with which the DC link capacitance is precharged via the Line Module is
determined using the following formula:
The DC link capacitances of the individual components can be taken from the relevant
technical data.
Smart Line Modules Booksize Compact
5.2.1
The Smart Line Module booksize compact is a non-regulated infeed/regenerative feedback
unit. The Smart Line Module supplies the Motor Module with a non-regulated DC voltage at
the DC output. In the infeed mode the Smart Line Module exhibits the typical current and
voltage waveforms of a 6-pulse diode rectifier bridge.
In feedback mode, the current waveform is square waved. The regenerative feedback can
be deactivated by means of parameters.
A line contactor can be installed on the line side if the system has to be electrically isolated
from the line supply.
The Smart Line Module in booksize compact format can be used with cooling types "internal
air cooling" or "cold plate". The cooling type is selected by parameter (see the SINAMICS
S120/S150 List Manual).
Smart Line Modules are suitable for direct operation in TN, IT, and TT systems. The Line
Modules have an integrated overvoltage protection function.
