Setting range: 0.00–10.00s
P09.07
Sampling cycle
(T)
This parameter means the sampling cycle of the
feedback. The modulator calculates in each
sampling cycle. The longer the sapling cycle is,
the slower the response is.
Setting range: 0.000–10.000s
0.100s

P09.08
PID control
deviation limit
The output of PID system is relative to the
maximum deviation of the close loop reference. As
shown in the diagram below, PID adjustor stops to
work during the deviation limit. Set the function
properly to adjust the accuracy and stability of the
system.

P09.09
Output upper
limit of PID
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

Feedback
offline detection
value
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 VFD will
report "PID feedback offline fault" and the keypad
will display PIDE.
