Automatically Adjusted Function Settings

You can specify whether to automatically adjust the following functions during autotuning.
 Automatic Notch Filters
Normally, set Pn460 to n.1 (Adjust automatically) (default setting).
Vibration will be detected during autotuning without a host reference and a notch filter will be
adjusted.
Set Pn460 to n.0 (Do not adjust automatically) only if you do not change the setting of
the notch filter before you execute this function.
Pn460
 Anti-Resonance Control Adjustment
This function reduces low vibration frequencies, for which the notch filters cannot be used.
Normally, set Pn160 to n.1 (Adjust automatically) (default setting).
Vibration will be detected during autotuning without a host reference and anti-resonance con-
trol will be automatically adjusted.
Pn160
 Friction Compensation
Friction compensation compensates for changes in the following conditions.
• Changes in the viscous resistance of the lubricant, such as 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
The conditions for applying friction compensation depend on the mode selection.
1: Standard
2: For position control
3: For position control (emphasis on overshooting)
