Beschreibung
Zusammenfassung:	An output module for connection to a DC voltage intermediate circuit of a drive control system for an electrical drive comprises a frequency converter which is connected between the DC voltage intermediate circuit and an output of the output module, and a module controller for controlling the frequency converter. The module controller is configured to control the frequency converter in a first operating mode of the output module in such a manner that an electrical motor is driven with an electrical drive current from the DC voltage intermediate circuit via the output. The module controller is configured to control the frequency converter in a second operating mode of the output module in such a manner that an electrical feedback current from the DC voltage intermediate circuit is fed back into an electrical supply network via the output.
