Feedback function
combination
0: No combination, feedback source 1
of feedback sources 1 and 2
2: Difference between feedback sources 1 and 2
3: Average of feedback sources 1 and 2
4: Minimum of feedback sources 1 and 2
5: Maximum of feedback sources 1 and 2
6: Min. negative difference or max. negative
difference among m
ultiple reference values
When calculating the difference between
reference source 1 and feedback source 1 and
difference between reference source 2 and
feedback source 2, give priority to the condition in
which the feedback is greater than the reference.
f there are some feedback values that are
greater than the reference values, select the
group with the max. negative difference as the
PID reference and feedback. If all feedback
values are less than the reference values, select
the group with the min. positive difference as the
PID reference and feedback.
7: Max. positive difference or min. negative
difference among multiple reference values
When calculating the difference between
reference source 1 and feedback source 1 and
the difference between referenc
e source 2 and
feedback source 2, give priority to the condition
in which the feedback is less than the reference.
If there are some feedback values that are less
than the reference values, select the group with
the max. positive difference as the PID reference
and feedback. If all feedback values are greater
than the reference values, select the group with
the min. negative difference as the PID reference
and feedback.
