5.4 Details of Function Codes
This section provides the details of the function codes. The descriptions are, in principle, arranged in the
order of function code groups and in numerical order. However, highly relevant function codes are
collectively described where one of them first appears.
5.4.1 F codes (Fundamental functions)
F00
Data Protection
F00 specifies whether to protect function code data (except F00 iteself) and digital reference data (such as
frequency command and PID command) from accidentally getting changed by pressing the
/ keys on
the keypad.

Only F00 data can be modified with the keypad, while all other function codes cannot.
To change F00 data, simultaneous keying of
+ or of + keys is required.
For similar purposes, WE-KP, a signal enabling editing of function code data from the keypad is provided as
a terminal command for digital input terminals. (Refer to the descriptions of E01 through E09. data = 19)
The relationship between the terminal command WE-KP and F00 data are as shown below.

y If you mistakenly assign the terminal command WE-KP, you can no longer edit or modify
function code data. In such a case, temporarily short circuit this WE-KP-assigned terminal with
the terminal [CM], and reassign the WE-KP to a correct command.
y WE-KP is only a signal that allows you to change function code data, so it does not protect the
frequency settings or PID speed command specified by
and keys.
