Quality factor of the bandpass filter (P-AXIS-00752)


Quality factor of the band-pass filter


Specifies the inverse value of the bandwidth for the band-pass filter for all modes (P-AXIS-00753).

P-AXIS-00752 = P-AXIS-00751 / bandwidth

A high filter quality limits the bandwidth of the filtering frequencies. To avoid cutting off any relevant frequencies, it is advisable to raise the filter quality step by step. The filter quality is limited by changing the frequency dependent on machine position and mass inertia. Among other things, a higher filter quality leads to improved damping of the required frequency, whereas a lower quality results in a more robust behaviour of frequency damping.
