<P>PROBLEM TO BE SOLVED: To provide a motor control system having a motor controller 1, a motor 31 and a sensor 41, in which the power supply to the sensor 41 and transmission/reception of a sensor signal can be carried out surely, even in case of a long cable while saving cable wiring and reducing the cost. <P>SOLUTION: The motor control system comprises a servo side signal transmitting/receiving section 13, a sensor side signal transmitting/receiving section 422, and a sensor side control power supply 423 interconnected via power supply lines 51 to the motor 31. Power supplied from the motor controller 1 to the sensor 41, and a sensor signal transmitted/received between the motor controller 1 and the sensor 41 are superimposed on the power supply lines 51 to the motor 31. <P>COPYRIGHT: (C)2007,JPO&INPIT |
