Butterworth
0.1 Hz to 25 Hz
Static inclination measurement with high damping against
vibrations
Critically
damped
0.1 Hz to 8 Hz
Inclination measurement for applications subject to specific
dynamics / without overshoot in the event of changes in
angle combined with good damping
The digital filter is selected via entry 3000.01h. The limit frequency is set via object
3000.02h. Values from 100 (= 0.1 Hz) to 25,000/8,000 (= 25 Hz/8 Hz) are permitted.
