Proportional gain can maximize its setting range up to 100 times by using the function selection flag of the PIDCAL command.
By enabling this function, the range value of Kp can be expanded from 1 to a maximum of 6,553,500.

Compared to the preceding versions of PID control, accuracy has been improved for the PID_2 functions and the Auto Tuning algorithm has been modified
so that it can now be implemented to a wider range of applications.
To obtain an enhanced effect of reaching the target value more quickly, the self-learning function has also been added for the PID_2 functions.
These new functions are built into CPU modules, which are produced since the year of 2012, and available in the firmware versions described in the table above.
