5.2.6 Notch filter
In case of low machine stiffness, you cannot set up a higher gain because vibration and noise occur due
to oscillation caused by axis distortion or other causes. By suppressing the resonance peak at the notch
filter, higher gain can be obtained or the level of vibration can be lowered.
Relevant parameters
MINAS A6 Multi series feature 5 normal notch filters. You can adjust frequency and width and depth.
