5.5.2 One-parameter Tuning Procedure
(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.)
If this function is set to Auto Setting, vibration will be detected automatically during one-parameter tuning 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 one-
parameter tuning.
Pn460
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 one-parameter tun-
ing and anti-resonance control will be automatically adjusted and set.
Pn160
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. The friction compensa-
tion setting in F408.3 applies when the mode is 0 or 1. Tuning Mode = 2 and Tuning Mode = 3 are adjusted
with the friction compensation function regardless of the friction compensation setting in P408.3.
