P09.08
Limit of PID
control deviation
It is the max. allowable deviation of PID system
output value relative to closed-loop reference
value. Within this limit, PID regulator stops
regulation. Set this function code properly to
regulate the precision and stability of PID system.
Setting range: 0.0–100.0%

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%

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.
