Abstract: 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.

Abstract: A supply module for supplying electric current to a drive module includes a first connecting contact and a second connecting contact. The first connecting contact is configured to connect the supply module to the drive module. The second connecting contact is configured to provide a connection to a power supply. At least one fuse element is arranged between the first connecting contact and the second connecting contact, the fuse element being connected to the two connecting contacts and being configured to limit a current flow between the first connecting contact and the second connecting contact.
