Example 2:
Starting PIDAT(191) with
Autotuning
At the rising edge of CIO 000000 (OFF to ON), autotuning will be performed
first if bit 15 of D00209 (C+9) is ON. When autotuning is completed, the calcu-
lated P, I, and D constants are written to C+1, C+2, and C+3. PID control is
then started with the calculated PID constants.
Example 3:
Interrupting Autotuning
Before Completion
Autotuning can be interrupted by turning bit 15 of D00209 (C+9) from ON to
OFF. PID control will be restarted with the P, I, and D constants that were in
effect before autotuning was started.
