Control device for a passenger transport system

The invention relates to an electrical control device (23) for controlling the drive of a passenger transport system (1) which can be switched between load operation and idle operation, wherein the electrical control device (23) comprises at least a three-phase mains voltage connection (31), a frequency converter (33), and a controllable switching device (35). The switching device can couple the three phases (U2, V2, W2) of the drive motor (25) to the three phases (R, S, T) of the mains voltage connection (31) in a load operation switching state (B2) and to the three phases (U1, V1, W1) of the frequency converter (33) in an idle operation switching state (B1), such that the drive motor (25) is supplied with the three-phase mains voltage (UN) in the load operation switching state (B2) and with the three-phase output voltage (UAC1, UAC2, UAC3) of the frequency converter (33) in the idle operation switching state (B1). Here, the frequency converter (33) is supplied via at least one phase (R, S, T) of the three-p
