10. Spindle Functions
Spindle phase alignment
Spindle phase synchronization starts when the spindle phase synchronous control signal (SPPHS)
is input during the spindle synchronization control mode. The spindle phase synchronization
complete signal is output when the spindle synchronization phase reach level setting value (#3051
spplv) is reached.
The synchronous spindle's phase shift amount can also be designated from the PLC.

Explanation
Spindle phase synchronization starts when this
signal is turned ON during the spindle
synchronous control mode.
(Note 1) If this signal is turned ON in a mode
other than the spindle synchronous
control mode, it will be ignored.
This signal is output when the spindle
synchronization phase reach level is reached
after starting spindle phase synchronization.
Designate the synchronous spindle's phase shift
amount.
