P09.06
Derivative time
(Td)
It determines the intensity of the regulation made on
the change rate of deviation between PID feedback
and reference by PID regulator. If feedback changes
by 100% during this period, the regulation of
differential regulator (ignoring integral and differential
actions) is Max. output frequency (P00.03)
The longer the derivative time, the stronger the
regulation intensity.
Setting range: 0.00–10.00s
0.00s ○
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%

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
