DC power supply modules Device features 6 6.1 Energy exchange in the DC bus If one or more controllers operate in generator mode (braking), the energy will be fed into the shared DC bus. The energy will then be available to the controllers in the system which operate in motor mode. The energy for the drive system can be supplied from the three-phase AC mains via: ƒ a E94APNExxx4 DC supply module ƒ a regenerative power supply module ƒ one or more controllers Advantages of the drive system Interconnecting the drives in a DC bus minimises the DC power to be supplied and to be regenerated. The rated power of the brake and supply units is thus reduced.
The energy consumption from the three-phase AC mains is reduced and the number of mains input modules and the related expenses (e.g. wiring) can be perfectly adapted to your application. 6.1-2 EDS94SPP101 EN 3.1-04/2007
