5.3 Description of Function Codes
This section describes details of function code. In principle, explanation is given for each function code in order of
group and numerical order. However, function codes that are strongly related to one function are explained together
in the first paragraph.
5.3.1 F codes (Fundamental functions)
F00
Data protection
This is a function to protect currently set data by disabling to make changes in function code data (except F00) and
all types of command values (frequency setting, PID command) by / key operation from keypad.
F00 data
Function code change
Command value

* Function codes cannot be changed at the keypad, however, function code F00 can be changed.
F00 data can be changed using the " key + key", or " key + key" double operation.
As a similar function related to data protection, “Allow function code editing (Data change enabled) ‘WE-KP’” which
can be assigned to a digital input terminal is available ( Function code E01 to E09 data = 19).
By combining data protection F00, protection of function code functions as follows:
Input signal “WE-KP”
Function code change
Changes from the keypad
Change from communication
OFF
Not allowed
Allowed
ON
Follow setting of F00
If “enable data change with keypad” [WE-KP] is set to a digital input terminal by mistake, it is not
possible to make changes in function codes. In this case, after shortening (ON) the terminal to which
temporarily “WE-KP” function is assigned, and the terminal [CM], change to a different function.
“WE-KP” is the change enable signal for function code, this is not the function to protect frequency
setting and PID command by / key operation.
