What If The Function Code Cannot Be Changed?I can not change it even if I try to change the function code setting ( 0 - 1 Etc.), the following cases are assumed:

Data protection is applied

F00 (Data protection) function, there is a possibility that various command values ??(frequency setting, PID command, timer operation time) can not be changed carelessly from the touch panel. If you want to change it, use "STOP Key + UP Key" or "STOP Key + DOWN Key" simultaneously (*double key operation).

* Double key operation = Pressing two keys at the same time is called double key operation.
