Description

The self-commutating infeed / regenerative feedback units act as step-up converters and
generate a stabilized DC link voltage that is 1.5x greater (factory setting) than the rated line
supply voltage. In this way, the connected Motor Modules are isolated from the line voltage.
This improves the dynamic response and control quality because line tolerances and
fluctuations do not affect the motor voltage.
If required, the Active Line Modules can also provide reactive power compensation.
