The following examples show how filtering works in the event of an input jump or disturbance.
Example 1
The input value jumps from 8000 to 16000. The diagram shows the calculated value with the following settings:
Input ramp limitation = 0
Filter level = 2 or 4
16000
8000
Example 2
A disturbance interferes with the input value. The diagram shows the calculated value with the following settings:
Input ramp limitation = 0
Filter level = 2 or 4
16000
8000
