Automatically Adjusted Function Settings

You can specify whether to automatically adjust the following functions during autotuning.
 Automatic Notch Filters
Normally, set Pn460 to n.1 (Adjust automatically) (default setting).
Vibration will be detected during autotuning without a host reference and a notch filter will be
adjusted.
Set Pn460 to n.0 (Do not adjust automatically) only if you do not change the setting of
the notch filter before you execute this function.

 Anti-Resonance Control Adjustment
This function reduces low vibration frequencies, for which the notch filters cannot be used.
Normally, set Pn160 to n.1 (Adjust automatically) (default setting).
Vibration will be detected during autotuning without a host reference and anti-resonance con-
trol will be automatically adjusted.

 Vibration Suppression
You can use vibration suppression to suppress transitional vibration at a low frequency from 1
Hz to 100 Hz, which is generated mainly when the machine vibrates during positioning.
Normally, set Pn140 to n.1 (Adjust automatically) (default setting).
Vibration will be detected during autotuning without a host reference and vibration suppression
control will be automatically set.
Set Pn140 = n.0 (Do not adjust automatically) only if you do not change the settings for
vibration suppression before you execute autotuning without a host reference.
Note: Autotuning without a host reference uses model following control. Therefore, it can be executed only if the
mode is set to 2 or 3.
