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