P09.08
PID control
deviation
limit
The output of PID system is relative to the
maximum deviation of the close loop reference.
As shown in the diagram below, PID adjustor
stops to work during the deviation limit. Set the
function properly to adjust the accuracy and
stability of the system.

Feedback
offline
detection
value
Set the PID feedback offline detection value,
when the detection value is smaller than or
equal to the feedback offline detection value,
and the lasting time exceeds the set value in
P09.12, the VFD will report "PID feedback
offline fault" and the keypad will display PIDE.
