Auto Mode (Continuous adjustment)) 
This Auto Mode provides continuous adjustment of loop gains according to measured inertia 
automatically. It is suitable when the load inertia is fixed or the load inertia change is small and is not 
suitable for wide range of load inertia change. The period of adjustment time is different depending on 
the acceleration and deceleration of servo motor. To change the stiffness and responsiveness, please 
use parameter P2-31.
