In this case the 3 dB bandwidth is determined on the following basis:
f
bandwidth
= 2 * f
block.
If instead of complete attenuation, a reduction by a factor of k is all that is required, then
the numerator damping should be selected in accordance with k.

"Bandstop filter with additional amplitude response increase/decrease at high
frequencies":
In this case, the numerator and denominator natural frequencies are set to different
values. The numerator natural frequency determines the blocking frequency. By selecting
a lower (higher) denominator natural frequency than the numerator natural frequency,
you can increase (decrease) the amplitude response at high frequencies. An amplitude
response increase at high frequencies can be justified in most cases, as the controlled
system generally possesses a lowpass characteristic itself, i.e., the amplitude response
drops at high frequencies anyway.

Activation
2.17.2.1
Parameterization
Activation
The jerk filter is activated using the machine data:
MD32400 $MA_AX_JERK_ENABLE = TRUE
The jerk filter is active in all operating modes and with all types of interpolation.
Filter mode
The mode is selected using the machine data:
MD32402 $MA_AX_JERK_MODE =
mode
Mode = 1
(2nd-order filter)
Mode = 2
(Sliding mean value generation)
Mode = 3
(Bandstop filter)
2.17.3
Programming
Programmability
The function is not programmable.
