Description

Note
Refer to the layout diagrams and circuit diagrams provided on the enclosed customer CD for
the arrangement of components and interfaces, and for wiring.
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.
Under full load, the DC link voltage is higher than the rms value of the rated line voltage by a
factor of 1.30, and under partial load by a factor of 1.32.
Smart Line Modules are suitable for connection to grounded (TN, TT) and non-grounded (IT)
supply systems. The following voltages and power ratings are available:
Line voltage
380 ... 480 V 3 AC
500 ... 690 V 3 AC
The power rating can be increased by connecting Smart Line Modules in parallel.
