9.6 Autotuning without Host Reference9.6.6 Automatically Adjusted Function Settings9-319 Tuning9.6.6 Automatically Adjusted Function SettingsYou can specify whether to automatically adjust the following functions during autotuning. Automatic Notch FiltersNormally, set Pn460 to n.1 (Adjust automatically) (default setting).Vibration will be detected during autotuning without a host reference and a notch filter will beadjusted.Set Pn460 to n.0 (Do not adjust automatically) only if you do not change the setting ofthe notch filter before you execute this function. Anti-Resonance Control AdjustmentThis 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. Vibration SuppressionYou can use vibration suppression to suppress transitional vibration at a low frequency from 1Hz to 100 Hz, which is generated mainly when the machine vibrates during positioning.Normally, set Pn140 to n.1 (Adjust automatically) (default setting).Vibration will be detected during autotuning without a host reference and vibration suppressioncontrol will be automatically set.Set Pn140 = n.0 (Do not adjust automatically) only if you do not change the settings forvibration suppression before you execute autotuning without a host reference.Note: Autotuning without a host reference uses model following control. Therefore, it can be executed only if themode is set to 2 or 3.Parameter Function When Enabled ClassificationPn460(2460h)n.0Do not adjust the first stage notch filter auto-matically during execution of autotuning with-out a host reference, autotuning with a hostreference, and custom tuning.Immediately Tuningn.1(default setting)Adjust the first stage notch filter automaticallyduring execution of autotuning without a hostreference, autotuning with a host reference,and custom tuning.n.0Do not adjust the second stage notch filterautomatically when the tuning-less function isenabled or during execution of autotuningwithout a host reference, autotuning with ahost reference, and custom tuning.n.1(default setting)Adjust the second stage notch filter automati-cally when the tuning-less function is enabledor during execution of autotuning without ahost reference, autotuning with a host refer-ence, and custom tuning.Parameter Function When Enabled ClassificationPn160(2160h)n.0Do not adjust anti-resonance control automat-ically during execution of autotuning without ahost reference, autotuning with a host refer-ence, and custom tuning.
