Whether to stop the integral after output to the limit
After the PID operation output reached the maximum or minimum value, can selection whether to
stop the integral action. If selection for stop integral, then the PID integral stop calculation, which may
help to reduce the overshoot amount of PID.

This function code is used to determine whether PID feedback is lost.
When the PID feedback quantity is less than the feedback loss detection values FA-26, and duration
more than PID feedback loss detection time FA-27, frequency converter alarm fault Err. 23, and deal
with according to the selected fault processing method.

Used to select the PID in stop condition, PID whether to continue operations. General application in
the case of PID should stop operation under the stop condition.

○
When the PID feedback value is less than the lower limit, the PID regulation does not act, which is
mainly used to reduce PID regulation and maintain the stability of the system.
