PHASE SHIFT CALCULATION
—
REQUEST
[Function]
This signal calculates the phase error of the basic spindle during rotation synchronization, and save
it in the NC memory.
[Operation]
The phase error of the basic spindle and synchronous spindle is saved in the NC memory when this
signal is ON and the rotation synchronization command's (with no R address command) spindle
synchronization is completed (when "Spindle rotation speed synchronization complete" signal is
ON).
This signal turns ON when the spindle rotation is stopped before the rotation synchronization
command.
(Note 1) The phase cannot be aligned when calculating the phase shift.
(Note 2) If the handle mode is selected as the manual operation mode, the synchronous spindle
cannot be rotated with the handle.
