Description
changes by 100% during the time set by
P09.06, the regulation quantity of differential
regulator (ignoring proportional and integral
actions) is the max.
(P00.03).
The longer the differential time, the stronger
the regulation intensity.
Setting range: 0.00–10.00s
It means the sampling cycle of feedback
quantity. The regulator calculates once during
each sampling cycle. The longer the sampling
cycle, the slower the response speed.
Setting range: 0.001–10.000s
It means the max. allowed deviation quantity
of the PID system feedback value relative to
closed-loop reference value. Within the
deviation limit, PID regulator stops regulating,
this parameter can be used to regulate the
precision and stability of PID system.
Setting range: 0.0–100.0%
