Abstract: A motor control system includes host control circuitry configured to generate a first control command; a plurality of motor control apparatuses configured to control a plurality of motors, respectively, based on the first control command; and reference information output circuitry configured to output reference information to one of the plurality of motor control apparatuses which is configured to control one of the plurality of motors. The reference information relates to control of the plurality of motors. Each of the plurality of motor control apparatuses corresponds to a corresponding motor among the plurality of motors and includes information sharing circuitry configured to share the reference information among the plurality of motor control apparatuses via data communication; command conversion circuitry configured to convert the reference information into a second control command; and motor control circuitry configured to control the corresponding motor based on the second control command.

Abstract: A distributed motor control system includes motor control devices that individually control motors that coordinately drive an industrial machine. Each of at least two motor control devices of the motor control devices includes processing circuitry that performs sharing processing including sharing coordinated control data, used in coordinated driving of the industrial machine between the at least two motor control devices, via data communication, and control a corresponding motor using the coordinated control data shared via the sharing-processing.

Abstract: A slave device includes a first connector, a second connector, a switch, and a communication circuit. The switch is alternatively connectable to the first connector or the second connector according to a connection way via which the slave device is connected to a master device and another slave device. The communication circuit is connected to the first connector and the switch. The communication circuit is configured to transmit and receive a first communication signal to and from the first connector, and is configured to transmit and receive a second communication signal to and from the switch.

Abstract: A motor control system includes a mechanical apparatus configured to be driven by a motor, a position detector configured to detect position information of the motor, circuitry configured to control the motor, at least one sensor configured to detect information relating to at least one of the mechanical apparatus and the motor, and an input and output device including input-and-output connectors. The position detector and the input and output device are connected to the circuitry through a same communication path. The at least one sensor is connected to the input-and-output connectors of the input and output device. The position information is configured to be transmitted from the position detector to the circuitry. The information relating to the at least one of the mechanical apparatus and the motor is configured to be transmitted from the at least one sensor to the circuitry through the input and output device.
