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.
Claims20
A distributed motor control system, comprising:
- a plurality of motor control devices that individually controls a plurality of motors configured to coordinately drive an industrial machine,
- wherein each of at least two motor control devices of the plurality of motor control devices includes processing circuitry configured to perform 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, and the processing circuitry is configured to render the coordinated control data, processed by the motor control devices, referenceable by a second motor control device other than the respective one of the motor control devices, and reference the coordinated control data that has been rendered referenceable by the second motor control device and is processed by the second motor control device.
A motor control device for controlling one of a plurality of motors that coordinately drive an industrial machine, comprising:
- processing circuitry configured to perform sharing processing including sharing coordinated control data with other motor control devices via data communication, and control the one of the motors using the coordinated control data shared via the sharing processing,
- wherein the coordinated control data is used in coordinated driving with the other motor control devices that coordinately drive the industrial machine with the motor control device, and the processing circuitry is configured to render the coordinated control data, processed by the motor control device, referenceable by a second motor control device other than the motor control device, and reference the coordinated control data that has been rendered referenceable by the second motor control device and is processed by the second motor control device.
A distributed motor control method executed by a distributed motor control system having a plurality of motor control devices that individually controls a plurality of motors configured to coordinately drive an industrial machine, comprising:
- sharing, via data communication between at least two motor control devices in the plurality of motor control devices, coordinated control data used in coordinated driving of the industrial machine;
- and
- respectively controlling corresponding motors by the at least two motor control devices using the shared coordinated control data,
- wherein the sharing includes rendering the coordinated control data, processed by the motor control devices, referenceable by a second motor control device other than a respective one of the motor control devices, and referencing the coordinated control data that has been rendered referenceable by the second motor control device and is processed by the second motor control device.
