Acceleration and deceleration of spindle-mode servo
Unlike the acceleration and deceleration of normal spindle, the spindle-mode servo performs multi-step acceleration and
deceleration as illustrated in the figure below when the speed command changes.

To specify the acceleration and deceleration of spindle-mode servo motor control, configure the following spindle spec.
parameters.
These parameters are also used as multi-step acceleration/deceleration parameters of spindle synchronization control.
