 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 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. 
 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 you set this function to Auto Setting, vibration will be automatically detected during execution of auto-
tuning without a host 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 you set this function to Auto Setting, vibration will be automatically detected during execution of auto-
tuning without a host reference and vibration suppression control will be automatically adjusted and set. Set 
this function to Not Auto Setting if you do not change the setting for vibration suppression before executing 
autotuning without a host reference.
Note: This function uses model following control. Therefore, the function can be executed only if the mode selection is set 
to 2 or 3.
