Note 2.
When you set the rigidity, the user parameters given in the above table will change automati-
cally.
Note 3.
If you enable auto-tuning without setting the rigidity, tuning is performed using the user param-
eter settings (Pn102, Pn100, Pn101, and Pn401) as the target values.

Storing Online Auto-tuning Results (Fn007)
•
Online auto-tuning constantly calculates and refreshes the load inertia using the rigidity settings
(speed loop gain, position loop gain, etc.) as target values. When the power supply is turned OFF after
operations are complete, however, the calculated data is lost, and the next time the power supply is
turned ON, calculations will restart using Pn103 (inertia ratio) setting as the initial value.
