DC−bus operation
Term Description
DC bus The energy store in the controller or supply module from which the
controller modulates the AC voltage for the motor. The DC buses of several
controllers can be networked.
DC bus Electrical connection of the DC connections of several controllers via cable
or busbar.
DC−voltage level DC−voltage level in the DC bus
Power supply module Module with AC mains connection used to supply the DC bus of a drive
system with DC voltage.
Regenerative power supply module Power supply module with additional power regeneration into the AC
mains
Multi−axis controllers (Multi Drive) Controllers for connection to a DC bus. Multi−axis controllers have no AC
mains connection and no brake chopper.
Single−axis controllers (Single Drive) Controllers for connection to an AC mains or a DC bus. Single−axis
controllers have an integrated brake chopper.
Brake chopper Switching element in the controller used to dissipate excess energy in the
DC bus via a brake resistor.
Brake resistor High−performance resistor used to convert excess energy in the DC−bus
into heat.
Braking operation Motor operation in generator mode with energy feedback from the motor
to the controller.
