It can decrease the drive's vibration during load starts and stops by setting this parameter.
Also it will speed up to the setting frequency with the fastest and smoothest start-up current
when it detects small torque. At deceleration, it will auto stop the drive with the fastest and the
smoothest deceleration time when the regenerated voltage of the load is detected.
