Multi-speed acceleration/deceleration
Up to eight steps of acceleration/deceleration time constants for spindle synchronization can be
selected according to the spindle rotation speed.

10.8 Spindle synchronization control II
Explanation
The phase error during spindle phase
synchronous control is output as a pulse unit.
The lower limit value of the phase error during
spindle phase synchronous control is output
as a pulse unit.
The upper limit value of the phase error during
spindle phase synchronous control is output
as a pulse unit.
