Abstract:
This motor drive system (300) comprises motor drive devices (200a, 200b) and a controller (125). The motor drive device (200a) drives motors (100a, 124) on the basis of a drive command generated by a control unit (23). The motor drive device (200b) drives the motors (100b, 124) on the basis of a drive command generated by the control unit (23). The controller (125) generates a motor control valid command and controls the motor drive devices (200a, 200b) on the basis of the motor control valid command. The controller (125) outputs the motor control valid command to any one of the motor drive devices (200a, 200b), and the respective control units (23) stop the outputs of the drive commands during a period in which the motor control valid command has not been received.
