9.5.6 Automatically Adjusted Function Setting
You can also automatically adjust notch filters.
Normally, set Pn460 to n.1 (Adjust automatically) (default setting). Vibration is auto-
matically detected and a notch filter is set.
Set Pn460 to n.0 (Do not adjust automatically) only if you do not change the setting
of the notch filter before you execute the tuning-less function.

9.6 Estimating the Moment of Inertia
9.6.1 Overview
This section describes how the moment of inertia is calculated.
The moment of inertia ratio that is calculated here is used in other tuning functions. You
can also estimate the moment of inertia during autotuning without a host reference. Refer
to the following section for the procedure.
