Abstract
An apparatus for transmitting a position detection signal of a multi-shaft motor whereby a parallel-form detection signal that is output from position-detecting devices disposed on each of a plurality of motors and used for indicating a motor rotation position can be transmitted to motor drivers for controlling the driving of the motors via a group of a small number of wires. In the apparatus for transmitting a position detection signal of a multi-shaft motor, a transmission-side converter converts a parallel-form detection signal from rotary encoders to a serial signal and presents the resulting signal to a reception-side converter via a serial signal transmission path. The reception-side converter returns the received serial-form detection signal to a parallel-form signal and presents the signal to motor drivers.
