P09.05
Integral
time at high
frequency
(Ti)
It determines the speed of integral regulation
made on the deviation between PID
feedback and reference by PID regulator.
When the deviation between PID feedback
and reference is 100%, the regulation of
integral regulator (ignoring integral and
differential
actions),
after
undergoing
continuous regulation during this time period,
can reach max. output frequency (
P00.03
) or
max. output voltage (
P04.31
). The shorter
the integral time, the stronger the regulation
intensity.
Setting range: 0.00
–10.00s
0.10s

P09.06
Differential
time at high
frequency
(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
) or max.
output voltage (
P04.31
). The longer the
differential time, the stronger the regulation
intensity.
Setting range: 0.00
–10.00s

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
0.100s

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.
