Filter level
The input value is evaluated according to the filter level. An input ramp limitation can then be applied using this
evaluation.
Formula for the evaluation of the input value:
Example 1
The input value jumps from 8000 to 16000. The diagram shows the calculated value with the following settings:
Input ramp limiting = 0
Filter level = 2 or 4
