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 (Basic 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
Change of function code
Changing digital reference
data with the
/ keys
Change from keypad Change from communication
0 Allowed Allowed Allowed
1 Not allowed * Allowed Allowed
2 Allowed Allowed Not allowed
3 Not allowed * Allowed Not allowed
*Although it is not possible to change function code from keypad, function code F00 can be changed.
F00 data can be changed by the double key operation using “ key + key” or “ key + key”.
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 E05 Data = 19).
By combining data protection F00, protection of function code functions as follows:
Input signal “WE-KP”
Change in function code
Change from 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
anges 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.
nge enable signal for function code, this is not the function to protect frequency
setting and PID command by key operation.
