7.1 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.
– Required accessories ( 313)
– Set-up for operation on IT systems ( 331)
ƒ Regenerative power supply modules are designed as multi-range voltage units
(230/400/480/500 V).
ƒ There are two types of regenerative power supply modules:
– E94ARNE0134,
rated current: in motor mode 26 A, in generator mode 13 A,
device size: 3,
Design: compact basic device with installation backplane
– E94ARNE0244,
rated current: in motor mode 47 A, in generator mode 23.5 A,
device size: 3,
Design: compact basic device with installation backplane
ƒ Regenerative power supp ly modules are assigned to specifically designed mains
filters and can only be operated with them.
ƒ Regenerative power supply modules and filters can be mounted in the mounting
grid of th e 9400 series.
ƒ Regenerative power supply modules allow parallel supply. Your Lenze contact will be
pleased to help you with the dimensioning.
