Abstract:
1. Method for monitoring the safety of a transport system, which transport system comprises a transport appliance as well as a synchronous motor for moving the transport appliance and in which method: the motion information of the transport appliance is determined from the signal of the motion sensor of the transport appliance wherein the motion information of the transport appliance is determined from the electrical parameters of the synchronous motor the motion information of the transport appliance determined from the signal of the motion sensor of the transport appliance is compared with the motion information of the transport appliance determined from the electrical parameters of the synchronous motor, and if the motion information of the transport appliance determined from the signal of the motion sensor of the transport appliance deviates from the motion information of the transport appliance determined from the electrical parameters of the synchronous motor by more than the set limit value, an emergency stop is executed.
