S-curve Acceleration/Deceleration Time Setting (Pn314)
Set the S-curve time in the time width centered on the inflection points in acceleration/deceleration
relative to the acceleration or deceleration time set in Soft Start Acceleration Time (Pn312) or Soft
Start Deceleration Time (Pn313).
ta = Vc/1,000 x Pn312 x 1 ms
td = Vc/1,000 x Pn313 x 1 ms
ts = Pn314 x 1 ms
Here, ta must be greater than ts and td must be greater than ts.

Set the zero speed designation selection.
Set the threshold for transition to the position control servo lock mode.
Set the threshold for detecting the speed conformity output. If the
difference between the speed command and the motor speed is equal to
or less than the set threshold, the speed conformity output will be output.
This setting has a hysteresis of 10 r/min for detection.
Set the threshold for detecting the motor rotation speed detection output.
If the motor speed exceeds the set value, the motor rotation speed
detection output will be output.
This setting has a hysteresis of 10 r/min for detection.
