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.

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 inverter will report “PID feedback
offline fault” and the keypad will display PIDE.
