Parameters Disabled by Tuning-less Function
When the tuning-less function is enabled (Pn170 = n.1) (default setting), the parameters
in the following table are disabled.
Advanced Control-Related
Gain Selection-Related Parameters
The tuning-less function is disabled during Easy FFT and mechanical analysis for a vertical axis.
The gain-related parameters in the above table are enabled for Easy FFT and mechanical anal-
ysis for a vertical axis.
8.4.5
Automatically Adjusted Function Setting
You can also automatically adjust notch filters.
Normally, set Pn460 to n.1 (Adjust automatically) (default setting). Vibration is automati-
cally 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.
