(3) Related Functions on Advanced Autotuning by Reference
This section describes functions related to advanced autotuning by reference.

Notch Filter
Usually, set this function to Auto Setting. (The notch filter is factory-set to Auto Setting.)

If this function is set to Auto Setting, vibration will be detected automatically during advanced autotuning by
reference, and the notch filter will be set.
Set this function to Not Auto Setting only if you do not change the notch filter setting before executing
advanced autotuning by reference.

Anti-Resonance Control Adjustment
This function reduces low vibration frequency, which the notch filter does not detect.
Usually, set this function to Auto Setting. (The anti-resonance control is factory-set to Auto Setting.)
When this function is set to Auto Setting, vibration will be automatically detected during advanced autotuning
by reference and anti-resonance control will be automatically adjusted and set.

Vibration Suppression
The vibration suppression function suppresses transitional vibration at frequency as low as 1 to 100 Hz that is
generated mainly when positioning if the machine stand vibrates.
Usually, set this function to Auto Setting. (The vibration suppression function is factory-set to Auto Setting.)
When this function is set to Auto Setting, vibration will be automatically detected during advanced autotuning
by reference and vibration suppression will be automatically adjusted and set.
Set this function to Not Auto Setting only if you do not change the setting for vibration suppression before
executing advanced autotuning by reference.
Note: This function uses model following control. Therefore, the function can be executed only if the mode is set to 2 or 3.
