User Manual of EM730 Series Inverter Fig. 9-29 Schematic Diagram of Initial PID Output 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.
