PHASE OFFSET DATA
[Function]
With the spindle phase shift amount calculation function, the phase error of the basic spindle and
synchronous spindle is obtained and memorized by turning the PLC signal ON at executing the
spindle synchronization. The synchronous spindle can be rotated with the handle during the spindle
phase shift calculation, so the relation between spindles can be adjusted by seeing.
If the "Spindle phase synchronous control" (SPPHS) signal is input while the "Phase offset request"
signal (SSPHF) is ON, the phase error will be aligned based on the position shifted by the
memorized phase shift amount.
Such operation makes the phase alignment easy when clamping an irregular material over.
[Operation]
The phase error memorized by the phase shift calculation is output.
Unit: 360 ° /4096
(Note 1) This data is output only during the spindle synchronous control.
