deviation of PID feedback and reference.
When the deviation
of PID feedback and reference is
100%, the integral adjustor works continuously
after
the time (ignoring the proportional effect
and
differential effect) to achieve the
Max. Frequency
(P00.03) or the Max. Voltage (P04.31).
Shorter the
integral time, stronger is the adjustment
Setting range: 0.01~10.00s
P09.06
Differential
time(Td)
This parameter determines the strength of the
change ratio when PID adjustor carries out integral
adjustment on the deviation of PID feedback and
reference.
I
f the PID feedback changes 100% during the time,
the adjustment of integral adjustor (
ignoring the
proportional effect and differential effect) is the
Max.
Frequency (P00.03) or the Max. Voltage (P04.
31).
Longer the integral time, stronger is the adjusting.
Setting range: 0.01~10.00s
0.00s

P09.07
Sampling
cycle(T)
This parameter means the sampling cycle of
the
feedback. The modulator calculates in
each
sampling cycle. T
he longer the sapling cycle is, the
slower the response is.
Setting range: 0.00~100.00s
0.10s

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