(2) Related Functions on One-parameter Tuning
This section describes functions related to one-parameter tuning.
 Notch Filter
Usually, set this function to Auto Setting. (The notch filter is factory-set to Auto Setting.)
When you set this function to Auto Setting, vibration will be automatically detected during custom tuning with
a host reference and the notch filter will be adjusted.
Set this function to Not Auto Setting only if you do not change the notch filter setting before executing one-
parameter tuning

 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 custom tuning and
anti-resonance control will be automatically adjusted and set.

 Friction Compensation
This function compensates for changes in the following conditions.
• Changes in the viscous resistance of the lubricant, such as the grease, on the sliding parts of the machine
• Changes in the friction resistance resulting from variations in the machine assembly
• Changes in the friction resistance due to aging
Conditions to which friction compensation is applicable depend on the tuning mode.

Compensation
* 1. The friction compensation function is always enabled regardless of the friction compensation setting in
Pn408.3.
* 2. For details on Pn408.3, refer to 8.8.2 (1) Required Parameter Settings.
Function

ity function.
Does not set the 2nd notch filter automatically with
the utility function.
