15.5.3. Stand-along operation after PID Auto-Tuning
Here, with example, it explains how to execute PID control followed by PID auto-tuning.
(1) PID auto-tuning parameter setting
▪ PID auto-tuning parameters are set as same as examples of 15.4.2 Example of PID Auto-
tuning.
(2) Setting parameters of A/D input module and D/A output module
▪ Set the parameters of A/D input module and D/A output module as same as the example in
15.4.2 Example of PID Auto-tuning.
(3) PID parameter setting
(a) If double-clicking Parameter – Built-in Parameter – PID – PID Parameter, it shows the
built-in PID parameter setting window as seen in Figure 15.26.
[ Figure 15.26 Auto-tuning parameter setting window ]
(b) Set each parameter and click OK.
In the example, Loop 0 is set as follows.
RUN mode: automatic
- Set as automatic in order that PID control is executed as the built-in PID operation
outputs MV.
RUN direction: forward
- Since in the system, water level is going up as MV increases and pump’s rotation
velocity increases, it should be set as forward operation.
PWM Output: disabled
