Usually applied when there is rather sharp acceleration which might cause motor overshoot or
undershoot. To smoothen command signal, reduces impact to machines and eliminate vibration. If
Pr2.23 is set too high, overall time will be lengthened.
**Please wait for command to stop and after filter idle time to modify Pr2.23.
Filter switching time = (Pr2.23 set value x 0.1ms + 0.25ms)
