Stability reserve of designed filter not sufficient.
Description | It is not possible to design a stable filter for all filter parameters, e.g. due to the limited calculation accuracy. Possible solutions are:

- Reduce order P-AXIS-00140 of the filter
- Reduce the reciprocal bandwidth P-AXIS-00080 of band-pass or band-stop filters
- Choose a different filter prototype P-AXIS-00153
- Increase the ratio of cut-off frequency to sample rate

For further information see [FCT-A7// Section: Filter types]
