Bandwidth [Hz]
To suppress the mechanical resonance frequency, a band-pass filter can
be activated at the output of the velocity loop. The parameters for this
function are CR05, Rejection Frequency Velocity Loop and CR06,
Rejection Bandwidth Velocity Loop.
CR06, Rejection Bandwidth Velocity Loop sets the frequency range on
either side of the notch frequency in which the attenuation is less than
-3dB.
Example:
CR05 = 500 Hz,
CR06 = 200 Hz;
then: attenuation < -3dB in range of 400 - 600 Hz.
Parameter Value Action of CR06
-1 VZ1 filter with CR04 time constant
0 filter is off
>0 bandwidth for notch filter
