Beschreibung
Zusammenfassung:	In an asynchronous motor fed from an AC current network (A:Mp) via a frequency converter (5;6) and having an electronic control system (2;3) for controlling the operating voltage as a function of a comparison of a load-specific current signal, which can be detected by the electronic control system (2;3), with a corresponding control of the asynchronous motor (1) can be achieved with a low electronic expenditure by providing the current decay time (A1) as a load-specific current signal during which time the free-wheeling current following after voltage interruption in a motor winding path decreases by a specific degree.
