Description

The Smart Line Module 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. Feedback can be deactivated by
means of a terminal because these Smart Line Modules are not equipped with a DRIVE-
CLiQ connection.
The DC link starts precharging as soon as the line voltage is applied and is independent of
its phase sequence direction. Load can be applied to the DC link after the module has been
enabled. An optional main contactor is required for disconnecting the voltage.
Smart Line Modules are suitable for direct operation on TN, IT and TT systems. The Line
Modules have an integrated overvoltage protection function.
