If "Stop integral operation" is selected, the PID integral operation stops, which may help
to reduce the PID overshoot.
Function Code Parameter Name Setting Range Default
FA-26
Detection level of PID
feedback loss
0.0%: No detection
0.1%–100.0%
0.0%
FA-27
Detection time of PID
feedback loss
0.0–20.0s 0.0s
These parameters are used to judge whether PID feedback is lost.
If the PID feedback is smaller than the value of FA-26 and the lasting time exceeds the
value of FA-27, the AC drive reports Err31 and acts according to the selected fault protection
action.
Function Code Parameter Name Setting Range Default
FA-28 PID operation at stop
0: No PID operation at stop
1: PID operation at stop
0
It is used to select whether to continue PID operation in the state of stop. Generally, the PID
operation stops when the AC drive stops.
