Axis parameters
FREQUEN (P72)
The meaning of this parameter depends on the type of filter being applied.
On "low passing" and "FAGOR" filters, it indicates the break point frequency or frequency where
the amplitude drops 3 dB or it reaches 70% of the nominal amplitude.
-3dB = 20 log (A/Ao) ==> A = 0,707 Ao
For the "anti-resonance" (notch) filter, it indicates the mid frequency or frequency at which the
resonance reaches its maximum value.
NORBWID (P73)
Normal bandwidth.
This parameter is only taken into account for the "anti-resonance (notch)" filter type.
It is calculated with the following formula.
Points f1 and f2 correspond to the cutoff frequency or frequency at which its amplitude drops 3 dB
or reaches 70% of the nominal amplitude.
SHARE (P74)
Signal percentage that passes through the filter. This value must be equivalent to the percentage
overshooting of the resonance because it has to make up for it.
This parameter is only taken into account for the "anti-resonance (notch)" filter type.
