Anti-resonance filter (notch filter).
Starting the CNC up while Fagor filters are active.
When starting the CNC up, if the Fagor filters are active on any of the axes and g.m.p IPOTIME (P73)
=1, the CNC will display the following error message:
• Parameter TYPE=2 is incompatible with general parameter IPOTIME.
When starting the CNC up, if the Fagor filters are active on any of the axes and a.m.p SMOTIME
(P58) is other than 0, the CNC will display the following error message:
• Parameter TYPE=2 is incompatible with general parameter SMOTIME.
FREQUEN (P69)
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 (P70)
Standardized bandwidth.
This parameter is only taken into account for the "anti-resonance (notch)" filter type.
The "anti-resonance" (notch) filter must be used when
the machine has a resonance frequency to be
eliminated.

After the start-up, if the value of that parameter is not changed, the CNC will cancel
that parameter automatically.
Possible values
Between 0 and 500.0 Hz.
Default value: 30
Possible values
between 0 and 100.0
Default value: 1
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.
