Motor driving system and motor driving control unit

摘要

A motor driving system comprises a plurality of motor driving control units each for controlling a motor and a controller for issuing a control command to a motor driving control unit. The controller and each of the motor driving control units have communication interfaces for infrared communications capable of transreceiving the signals. A loop communication using infrared rays is executed between the controller and one of the motor driving control units and also among the motor driving control units.
