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.
Double key operation method
Settings requiring double key operation
Several function codes can be changed by double key operation to prevent unnecessary change. Therefore, when changing the code please change by double key operation.
F00 : Data protection function
F80 : HD / MD / LD switching
H03 : Data initialization
H45 : Simulated fault
H97 : Alarm data clear
Y97 : Select communication data saving method
Function codes that can not be changed during operation
There is a function code that can not be changed while the inverter is running. Please refer to the function code table of FRENIC MEGA user's manual for applicable function code.
