P09.07
Sampling cycle
(T)
It means the sampling cycle of feedback. The
regulator operates once during each sampling cycle.
The larger the sampling cycle, the slower the
response.
Setting range: 0.001–10.000s
0.001s

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%
Setting range of P09.10: -100.0%–P09.09

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.
