Load Inertia
Percentage
Properly setting the Load Inertia Percentage is a prerequisite for
the One-Parameter Auto-Tuning to obtain a better Servo
performance.
You can calculate the load inertia percentage (difficult and
complex) by yourself, or you can get it by the utility function
Fn009 or by ESView V4, certainly, you can directly modify the
parameters by the host controller.
Pn100.3
Damping Selection
Select a damping method according to your requirement and
application.

[0] Standard: Short positioning time, but prone to overshoot.

[1] Stable: Stable positioning, but long positioning time.

Servo Rigidity
The Servo Rigidity determines the response characteristic of the
position loop or speed loop.
The performance can be improved by increasing the Servo
Rigidity, and decrease it if a vibration occurs.
The figure below shows the speed step response for different
Servo Rigidities:
