Page 295 10. PLC Help Function 10.6 External Machine Coordinate System Compensation External machine coordinate system compensation is executed by setting compensation data (absolute amount) in the PLC file register (R) for each axis. Thus, the compensation timing is when PLC rewrites file register (R) compensation data. Necessary condition, timing, etc., are set by user PLC.
