Smart Line Modules are infeed/regenerative feedback units that supply power to connected Motor Modules. Furthermore, they are capable of feeding regenerative energy back into the grid. The infeed occurs over a diode jumper, while stable, line-commutated regenerative feedback takes place via IGBTs with 100 % continuous energy regeneration. The regenerative capability of the modules can be deactivated by means of parameterization.

Smart Line Modules are designed for connection to grounded TN/TT and non-grounded IT supply systems.

The DC link is pre-charged by means of integrated pre-charging resistors.

To operate the Smart Line Module, the associated line reactor or a suitable transformer is required.
