PID regulator can regulate the output frequency
command is the max. frequency (ignoring
integral function and differential function).
Setting range: 0.00–100.00
P09.05
High
frequency
integral time
(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

P09.06
High
frequency
differential
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) or max. output voltage
(P04.31). The longer the differential 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: 0.000–10.000s
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.
