Patent ID: 7388344

Claim:
A multichannel pulse train transmitting apparatus for transmitting motor position command pulses from a motor controller to motor drivers for controlling the driving of each of a plurality of motors, said apparatus comprising: a transmission-side converter provided with a serialization circuit; a reception-side converter provided with a deserialization circuit; controller-side multichannel parallel signal transmission paths for connecting the motor controller and the transmission-side converter; driver-side multichannel parallel signal transmission paths for connecting the reception-side converter and the motor drivers; and a serial signal transmission path for connecting the transmission-side converter and the reception-side converter; wherein the transmission-side converter collects motor position command pulse trains for the respective motors that are provided from the controller via the controller-side multichannel parallel signal transmission paths, converts the pulse trains to serial signals, and supplies the resulting serial signals to the reception-side converter via the serial transmission path; and the reception-side converter returns the received serial-form motor position command pulse trains to multichannel pulse trains in the form of a parallel signal and supplies the resulting parallel signals to the motor drivers via the driver-side multichannel parallel signal transmission paths.
