PID Feedback (FB) Upper/Lower Limit

If the feedback value exceeds the upper limit set in C052, FBV, which is allocated to the multi-func-
tion output terminal, turns on. If the value falls below the lower limit set in C053, FBV turns off.
This is effective as a RUN command in operating multiple pumps.

PID Operation

P Operation
•Operation where the control volume is proportional to the target value
I Operation
•Operation where the control volume increases linearly according to time
D Operation
•Operation where the control volume is proportional to the variation ratio of the target value
•PI operation is the combination of the above P and I operations; PD is P and D operations; PID is
P, I and D operations.
