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.
The tuning-less function is disabled during torque control, Easy FFT, and mechanical analysis
for a vertical axis. The gain-related parameters in the above table are enabled for torque con-
trol, Easy FFT, and mechanical analysis. Of these, Pn100, Pn103, and Pn104 are enabled for
torque control.
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.
8.4.6
Related Parameters
The following parameters are automatically adjusted when you execute the tuning-less func-
tion.
Do not manually change the settings of these parameters after you have enabled the tuning-
less function.
