AP.24

PID controller
differential
time
0ms
0 to
10000ms
Set the regulator differential time. Whenever
a greater response is needed, this value can
be increased.
Note: Increasing too much this value can
cause a precision loss.
YES
AP.25
[32]
PID output
fine
adjustment
+0.0%
0.0 to
1000.0%
Apply a fine adjustment at the PID output.
Use this parameter when an adjustment for
the proportional constant below 0.1% is
required.
YES
AP.26
[32]
Proportional
gain scale
100.0%
0.0 to
100.0%
This parameter, along with AP.22 allow
setting output ratio for errors between
reference and feedback. If AP.22 is set to
50%, then 50% of the error is output. For
ratios below 0.1% use AP.26.
NO
AP.27
[32]
PID Filter
0ms
0 to
10000ms
Used when the output of the PID controller
changes too fast or the entire system is
unstable, due to severe oscillation. In
general, a lower value (default value=0) is
used to speed up response time, but in
some cases a higher value increases
stability. The higher the value, the more
stable the PID controller output is, but the
slower the response time.
