An electrical control device for controlling the drive of a passenger transport system which can be switched between load operation and idle operation is described. The electrical control device includes at least a three-phase mains voltage connection, a frequency converter, and a controllable switching device. The switching device can couple the three phases of the drive motor to the three phases of the mains voltage connection in a load operation switching state and to the three phases of the frequency converter in an idle operation switching state. In this manner, the drive motor is supplied with the three-phase mains voltage in the load operation switching state and with the three-phase output voltage of the frequency converter in the idle operation switching state.
