12.3 Function
DC-bus connections of drive systems enable the exchange of energy between
connected controllers on the DC voltage level.
If one or more controllers operate in generator mode (braking), the recovered
energy will be fed into the shared DC bus or the DC source. The energy will then
be available to the network of controllers which operate in motor mode.
The energy from the three-phase AC mains can be supplied via the following
devices:
l 934X regenerative power supply unit
l 936X power supply unit
l One or several controllers
l A combination of 934X regenerative power supply units and controller
The use of brake units, supply units and the energy consumption from the
three-phase AC mains can be reduced.
The number of mains supply terminals and the related expenses (e.g. for wiring)
can be perfectly adapted to your application.
