(3) Related Functions
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 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.
Anti-Resonance Control Adjustment Function
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.
"ARES" will blink on the digital operator when anti-resonance control adjustment function is 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 load resistance resulting from fluctuations in the machine assembly
• Secular changes in the load resistance
Conditions to which friction compensation is applicable depend on the tuning mode. The friction compensa-
tion setting in Pn408.3 applies when the mode is 0 or 1.
