Abstract:
A method and a device for monitoring the startup of an electric drive, which has a polyphase machine, a pulse-controlled inverter and a control unit. The control unit is provided to compare rotational speed values that are successive in time to one another during the startup of the drive, and when recognizing a non-increase in the rotational speed of the rotor shaft, to detect a mixup of phase lines or pulse-controlled inverter lines.
