P09.09
Upper limit value
of PID output
These two function codes are used to set the
upper/lower limit value of PID regulator.
100.0% corresponds to Max. output frequency
(P00.03) or max. voltage (P04.31)
Setting range of P09.09: P09.10–100.0%
Setting range of P09.10: -100.0%–P09.09
100.0%

P09.11
Feedback offline
detection value
Set PID feedback offline detection value, when the
detection value is no more than the feedback offline
detection value, and the duration exceeds the value
set in P09.12, the inverter will report "PID feedback
offline fault", and keypad displays PIDE.

selection
0x0000–0x1111
Ones:
0: Continue integral control after the frequency
reaches upper/lower limit
1: Stop integral control after the frequency reaches
upper/lower limit
Tens:
0: The same with the main reference direction
1: Contrary to the main reference direction
0x0001
