Example 3: Using the automatic tuning function to control the temperature
Because you may not be familiar with the characteristics of the temperature environment to be controlled, you can use
the automatic tuning function to make an initial adjustment (PID_MODE is set to 1). After the automatic tuning of the
parameter is complete, PID_MODE is set to 0. The controlled environment in this sample is an oven. The following
example program shows the setting values for the instruction.

The experimental result of the automatic tuning function is shown in the following graph.
