PID Deviation limit
0.0%～100.0%
0.0%
☆
When the deviation of PID given value and feedback value is smaller than E2.06, PID
will stop regulating action, so the output frequency keeps steady, it is quite effective for
some close-loop control applications.
E2.07
PID Differential limit
0.00%～100.00%
0.10%
☆
Differentiation is a very sensitive role in PID regulator, it is easy to cause the system
oscillation, therefore, generally need to limit it in a small range, E2.07 is used to set the
range of PID differential outputs.
E2.08
PID reference change
time
0.00s～650.00s
0.00s
☆
PID reference change time, is the time of PID given value changes from 0.0% to
100.0%.
When PID given value changes, PID given value changes lineal in accordance with a
given reference change time, reduce the adverse effects to the system.

E2.09 is for PID feedback value filtering, the filter help to reduce the impact on the
amount of feedback is interference, but the process will bring the affect the responding
performance of closed-loop system.
E2.10 is for PID output frequency filtering, the filter will diminish the mutation of
output frequency, but the same process will bring the performance of closed-loop system
response decreased.
