G5 Series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type
The function sets the S-curve time for the acceleration and deceleration time set by the Soft Start
Acceleration Time (3312 hex) and the Soft Start Deceleration Time (3313 hex). The S-curve time is a
duration around an inflection point during acceleration and deceleration.
