A drive device for an electric motor is provided. The drive device decides based on signals it receives from outside whether it is monitoring an actual value of the electric motor with respect to the adherence to an actual value condition (monitoring operation). During monitoring operation, the drive device causes the motor to be disconnected from a power supply if the actual value does not adhere to the actual value condition. Via a communication connection, the drive device provides a drive control unit with first information, which reveals whether the drive device is in the monitoring operating mode. The drive device provides the drive control unit with second information, which reveals what the actual value condition is. Based on the first information, the drive control unit examines whether the drive device is in the monitoring operating mode. If this is the case, the drive control unit, based on the second information, determines what the actual value condition is. |
