the value of dynamic tracking error will
become very small. However, when the value
of SFG is too great, it may cause vibration.

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.
