Title:
COMMUNICATIONS SYSTEM FOR NUMERICAL CONTROL DEVICES AND COMMUNICATIONS METHOD FOR NUMERICAL CONTROL DEVICES
Document Type and Number:
WIPO Patent Application WO/2022/118782
Kind Code:
A1
Abstract:
The present invention addresses the issue of providing a communications system for numerical control devices and a communications method for numerical control devices, that have less communications traffic than is conventionally required. This communications system for numerical control devices includes a numerical control device, a converter device, and a plurality of inverter devices. This communications system for numerical control devices comprises an application unit and a determination unit. The application unit applies identification information to the inverter devices. The determination unit determines the inverter device, among the plurality of inverter devices that have had identification information applied thereto, that will be used for communications with the numerical control device and the converter device. The numerical control device comprises a numerical control communications unit that communicates with the inverter device using a first transmission path. The converter device comprises a converter communications unit that communicates with the numerical control device via: a second transmission path different from the first transmission path; the inverter device determined by the determination unit; and the first transmission path.
