10.1 Function
ƒ DC−bus connections of drive systems enable the exchange of energy
between connected controllers.
ƒ 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.
ƒ The use of braking units and supply units can be reduced.
ƒ The energy consumption from the three−phase AC mains can be
reduced.
ƒ The number of mains supplies and the related expenses (e.g. wiring)
can be perfectly adapted to your application.
