Detailed instruction
The shorter the integral time, the stronger the
adjustment intensity.
Setting range: 0.00–10.00s
It determines the intensity of the adjustment
made by PID regulator against the change rate of
deviation between PID feedback quantity and
reference quantity. If feedback quantity changes
100% during this time period, the adjustment
quantity of differential regulator (ignoring integral
and differential effect) is the maximum output
frequency (P00.03)
The longer the differential time, the stronger the
adjustment intensity.
Setting range: 0.00–10.00s
It means the sampling cycle of feedback quantity.
The regulator calculates once during each
sampling cycle. The larger the sampling cycle,
the slower the response.
Setting range: 0.001–10.000s
It is the max. allowed deviation quantity relative
to close-loop reference value of PID system
feedback value. Within this limit, PID regulator
stops adjustment. Set this function code properly
to adjust the precision and stability of PID
system.
