Detailed instruction of parameters
Setting range: 0.000–10.000s
The output of PID system is the maximum
deviation corresponding to 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.
Reference
value
Output frequency
Setting range: 0.0–100.0%
This parameter is used to set the upper and lower
limit of the PID adjustor output.
100.0 % corresponds to max. frequency or the
max. voltage of ( P04.31)
Setting range of P09.09: P09.10–100.0%
Setting range of P09.10: -100.0%–P09.09
Set the detection value of feedback offline, when
the feedback detection value is smaller than or
equals to the detected 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.
