These parameters are 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 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.
