5.8.2 Adaptive Filter
Adaptive filter reduces vibration by automatically setting the notch filters by
performing real-time analysis on vibration frequency generated from the load during
drive operation through speed feedback signals.
One or two notch filters can be automatically set by detecting the vibration
frequency through frequency analysis. The frequency and width are automatically
set, and the set value is used for depth.
