<P>PROBLEM TO BE SOLVED: To provide a driving system of a motor capable of taking a preventive measure when a trouble is detected while reducing the system and the cost. <P>SOLUTION: Power converters 2-1 and 2-2 are connected, respectively, with winding 15-1 and 15-2 and drive a two circuit winding motor 5. A position detection signal, a speed detection signal, an output current detection signal, and an output voltage detection signal are duplicated. A main control circuit 3 compares each input detection signal with each detection signal being transferred from a monitoring control circuit 4 through high speed communication and outputs a gate signal to the power converters 2-1 and 2-2 thus controlling the two circuit winding motor 5. The monitoring control circuit 4 has a function similar to that of the main control circuit 3 and performs modeling of the entire system including the load/machine, monitors control state of the main control circuit 3 constantly, and switches a gate signal switch 6 to output the gate signal from the monitoring control circuit 4 to the power converters 2-1 and 2-2 when a trouble is detected in the main control circuit 3. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
