SPINDLE PHASE

SYNCHRONOUS CONTROL
[Function]
Spindle phase synchronization starts this signal is turned ON during the spindle synchronous
control mode.
[Operation]
Spindle phase synchronization starts when the "Spindle phase synchronous control" signal
(SPPHS) is input during the spindle synchronous control mode. The "Spindle phase
synchronization complete" signal is output when the spindle phase synchronization attainment level
setting value (#3051 spplv) is reached.
(Note 1) This signal will be ignored even if it is turned ON during a mode other than the spindle
synchronous control mode.
