PID Control

Operates as Pid control when the parameter "P P P P " is not set to
0.0 ("P P P P i i i i d d d d C C C C h h h h 2 2 2 2 "), and "C C C C T T T T r r r r L L L L " is equal to Pid ("S S S S Y Y Y Y S S S S C C C C h h h h 7 7 7 7 "). Pid
controls calculate Pid and output the result according to the set
values of the parameters "P P P P ", "i i i i ", "d d d d ", and "A A A A r r r r ".(-3% to 103%)
Each parameter can be set either by manually tuning the values
or by running auto-tuning (AT) to automatically set the values.
Refer to
See "Auto-tuning" for more about the auto-tuning function.
