<P>PROBLEM TO BE SOLVED: To provide a servo motor control system improvable in the saving of wiring and noise-proof performance. <P>SOLUTION: The servo motor control system 1 is composed of a servo driver 2, a servo motor side receiving part 3 and an optical signal transmission part 4 that connects the driver and the receiving part. A control signal E-O conversion part 21 that converts a control signal for controlling the position or the like of a serve motor 8 into an optical signal from an electrical signal is arranged at the servo driver 2, the optical signal transmission part 4 transmits the optical signal from the control signal E-O conversion part 21 to the servo motor side receiving part 3, and at the servo motor side receiving part 3, there are arranged a control signal O-E conversion part 33 that converts the received optical signal to the electric signal, and a power circuit 38 that controls the position or the like by receiving the control signal that is reconverted into the electric signal by the control signal O-E conversion part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
