The PID output is limited. The output range of the PID module in the whole process is
(F09.17, F09.16). That is, if the actual adjustment result is beyond this range, the output will be
based on the boundaries.

●
When the deviation between the PID setting and feedback is less than or equal to the
deviation limit (F09.18), the PID will stop the adjustment. When the deviation between the
setting and feedback is smaller, the output frequency will remain stable. This is valid for some
closed-loop control applications.
