PID. For example, the strain PID control during wrap
down
The function is applied to the proportional gain P of
PID input.
P determines the strength of the whole PID adjuster.
Proportion
The parameter of 100 means that when the offset of
P09.04 al gain
PID feedback and given value is 100%, the adjusting
(Kp)
range of PID adjustor is the Max. frequency (ignoring
integral and differential function).
The setting range:0.00~100.00
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
Integral 100%, the integral adjustor works continuously after
P09.05
time(Ti) 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: 0.00~50.00s
This parameter determines the strength of the
change ratio when PID adjustor carries out integral
adjustment on the deviation of PID feedback and
reference.
Differential If the PID feedback changes 100% during the time,
P09.06
time(Td) 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
Sampling This parameter means the sampling cycle of the
P09.07
cycle(T) feedback. The adjustor operates each sampling
