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 wrap-up
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 wrap-down

P09.04
Proportional
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 reference 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
Integral
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: 0.01~10.00s
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
0. 00s
