Description

Smart Line Modules are infeed/regenerative feedback units. Like the Basic Line Module,
they supply energy to the connected Motor Modules, but unlike the Basic Line Module, they
can feed back regenerative energy.
The infeed occurs over a diode jumper, while stable, line-commutated regenerative feedback
takes place via IGBTs with 100% continuous energy regeneration.
The DC-link voltage is greater than the rms value of the line rated voltage by a factor of 1.32
(under partial load) or 1.30 (under full load).
