Functional description
The energy of controllers connected in a DC−bus system can be exchanged on
DC−bus level.
If one or more controllers operate in generator mode (braking operation),
the energy will be fed into the shared DC−voltage bus. The energy will then
be available to the controllers which operate in motor mode.
The energy for the drive system can be supplied from the three−phase
system via
ƒ a 934X regenerative power supply module.
ƒ a 936X power supply module.
ƒ one or more controllers.
ƒ a combination of a 934X regenerative module or 936X power supply
module and a controller.
The number of braking units and power supply units may be reduced and the
energy consumption from the mains can also be reduced at the same time.
The number of mains supply points can be optimally adapted to the
application.

Note!
ƒ
Centralised supply (one input module):
– Configure the multi−axis application using the Lenze »Drive
Solution Designer« (DSD).
– DSD provides support for the selection of suitable
components and for the optimisation of the DC−bus system.
ƒ
Decentralised supply (several input modules):
– Consult your Lenze contact person.
