Detailed instruction of parameters
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
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
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). Longer the integral time, stronger is the
adjusting.
Setting range: 0.00~10.00s
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.
Setting range: 0.00~100.00s
As shown in the diagram below, PID adjustor stops to
work during the deviation limit. Set the function properly
to adjust the accuracy and stability of the system.
