Auto Mode (Continuous adjustment))

When Tuning Mode Settings of P2-32 is set to 1, the ratio of Load Inertia to servo motor inertia can be

continuously adjusted. 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.

Inertia Measurement

Auto Mode (The ratio of Load Inertia to servo motor inertia is fixed)

When Tuning Mode Settings of P2-32 is changed from 1 to 2, the measured load inertia value will be

saved and memorized in P1-37 automatically. Otherwise, the users should set the ratio of load inertia to

servo motor inertia via parameter P1-37 in advance. To change the stiffness and responsiveness,

please use parameter P2-31.
