(2) Details of input signals (CNC → PMC)
(a) Spindle synchronous control signal SPSYC
[Function] Specifies switching to spindle synchronous control mode.
[Operation] When this signal is set to 1, spindle synchronous control mode is set.
When this signal is set to 0, spindle synchronous control mode is
cancelled.
(b) Spindle phase synchronous control signal SPPHS
[Function] Specifies spindle phase synchronous control mode (phase matching).
(i) This function is valid when the spindle synchronous control
signal SPSYC is 1.
(ii) After the spindle synchronous speed control completion signal
FSPSY is set to 1, specify this signal.
(iii) A spindle phase synchronous control operation is performed on
the rising edge of this signal. So, the phase once matched is not
shifted by setting this signal to 0.
However, a phase matching operation is performed when this
signal is changed from 0 to 1 again.
[Operation] When this signal makes a transition from 0 to 1, spindle phase
synchronous control is exercised.
