Device features

The most important device features at a glance:

ƒ

Regenerative power supply modules supply the DC buses of several controllers of a

drive system with energy.

ƒ

Regenerative power supply modules feed braking energy back to the AC mains.

ƒ

Regenerative power supply modules with the assigned mains filter are the central

AC mains connection within DC-bus operation.

ƒ

Regenerative power supply modules have an internal brake chopper and a terminal

for a brake resistor.

ƒ

Regenerative power supply modules of the 9400 series are equipped with a busbar

connection (max. 100 A) for the simple connection and side-by-side mounting of the

9400 controllers.

ƒ

Regenerative power supply modules generally supply controllers of the ”Multi Drive”

version. However, also controllers of the ”Single Drive” version can be implemented

in a DC-bus operation if the data and notes in the ”DC-bus operation” chapter are

observed.
