5.14 Detecting Sudden Input Changes
The previous average value comparison function can be used to detect only sudden changes in input
signals.
Use the previous average value comparison to not detect gentle changes and only detect sudden
changes.
As shown in the above diagram, when rotating a cylindrical object and measuring the distance from the
object using a laser displacement meter, it cannot be judged if the increase in measurement values when
the rotating axis is eccentric is due to the eccentricity or to a burr.
