P09.03
PID output
feature
0: PID output is positive: when the feedback
signal exceeds the PID reference value, the
output frequency of the inverter will decrease
to balance the PID. For example, the strain PID
control during wrapup
1: PID output is negative: When the feedback
signal is stronger than the PID reference value,
the output frequency of the inverter will
increase to balance the PID. For example, the
strain PID control during wrapdown
0

P09.04
Proportiona
l gain (Kp)
The function is applied to the proportional gain
P of PID input.
P determines the strength of the whole PID
adjuster. The parameter of 100 means that
when the offset of PID feedback and given
value is 100%, the adjusting range of PID
adjustor is the Max. frequency (ignoring
integral function and differential function).
The setting range:0.00~100.00
1.00

P09.05
Interval
time(Ti)
This parameter determines the speed of PID
adjustor to carry out integral adjustment on
the 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: 0.00~10.00s
0.10s

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.
If 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: 0.00~10.00s
0.00s

P09.07
Sampling
cycle(T)
This parameter means the sampling cycle of
the feedback. The modulator calculates in each
sampling cycle. The longer the sapling cycle is,
the slower the response is.
0.100s
