User Manual of A90 Series Inverter Output frequency Initial PID value F09.14 Time 0 Holding time of initial PID value (F09.15) Fig. 7-28 Schematic Diagram of Initial PID Output (F09.17, F09.16). That is, if the actual adjustment result is beyond this range, the output The PID output is limited. The output range of the PID module in the whole process is 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.
If the input terminal function “41: process PID pause” is valid, the PID will also stop the adjustment. Users need to use these two modes together. The differential (D) component of the PID regulator must not be greater than the PID 204 Default Function code Function code name Parameter description Unit Attribute setting F09.16 Upper limit of PID output F09.17 - +100.0 % 100.0 ● F09.17 Lower limit of PID output –100.0 - F09.16 % 0.0 ● Default Function code Function code name Parameter description Unit Attribute setting F09.18 PID deviation limit 0.00-100.00 (0.00:
