Apparatus for transmitting position detection signal of multi-shaft motor

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 is transmitted to motor drivers for controlling the driving of the motors, said apparatus comprising:

• a transmission-side converter provided with a serialization circuit;
• a reception-side converter provided with a deserialization circuit;
• an encoder-side parallel signal transmission path for connecting the position detectors and the transmission-side converter;
• a driver-side parallel signal transmission path for connecting the reception-side converter and motor drivers;
• and
• a serial signal transmission path for connecting the transmission-side converter and the reception-side converter;
• wherein
• the transmission-side converter converts, to serial signals, parallel-form detection signals provided from the position-detecting devices via the encoder-side parallel signal transmission path, and presents the resulting signals to the reception-side converter via the serial signal transmission path;
• and
• the reception-side converter returns the received serial-form detection signals to parallel-form signals and presents the resulting signals to the motor drivers via the driver-side parallel signal transmission path.
