P09.07 Sampling cycle (T)
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
0.100s
○
P09.08
Final limit of PID
control deviation
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.
