14.14 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.
The interface between user PLC and CNC is shown below.
File register
R5700, 5701 $1 compensation data 1st axis
R5702, 5703 $1 compensation data 2nd axis
R5704, 5705 $1 compensation data 3rd axis
R5706, 5707 $1 compensation data 4th axis
R5708, 5709
R5710, 5711
R5712, 5713
R5714, 5715
Note
(1) File resisters for $1 are used for models with no part systems.
Data in file registers (R5700 to R5731) is not backed up. If it must be backed up, use back-up file registers (R8300 to R9799).
Note
(1) The maximum delay to compensation is (one user PLC scan + 15 ms). However, smoothing time constant and servo fol-
low delay are not contained.
