5.3 Description of Function Codes
5-188
■
Temporary decoding of password 1 (rewrite disable protection)
When password 1 protective status is shown and the same value as the password set for function code H198 is
entered in H198, password 1 protective status is temporarily released and the function code setting value can be
rewritten.
If password 2 is set at the same time, it is necessary to decode password 2 with H99 in advance.
Password temporary
decoding
(Function code rewrite
enable)
Select the protection target with
function code H197 and set the
password to function code H198.
Password protection
(Function code rewrite
disable)
Set 1 to function code H199 or the specified
period of time has passed after temporary
decoding of the password.
Set the correct password to
function code H198.
Set incorrect passwords to
function code H198. (Less
than 5 times)
Password
prot Occurrence
of minor failure (Function code
read/write disable)
(Inverter operation
enable)
Set incorrect passwords to
function code H198. (5 times)
Password
prot Occurrence
of LoK alarm (Function code
read/write disable)
(Inverter operation
disable)
Password not set
(Function code rewrite
enable)
After 20 minutes,
release the minor
failure.
Perform data initialization
[H03=1] with Fuji Electric
standard initial value [H02=0].
Set incorrect passwords
to function code H198.
(No. of specified times).
Perform data initialization
[H03=1] with Fuji Electric
standard initial value
[H02=0].

■
Password 2 (Read/write disable protection)
Setting values of all function codes not by selecting function code H197 can be protected as read disable and
rewrite disable. (Exceptionally, partial function codes are not protected.)
Set the password with function code H99 and set function code H199 to 1. Password 2 protective status (read/write
disable protection) is active.
The function code of read/write disable does not allow writing of the setting value to the inverter with a remote
touch panel, multi-function touch panel or external device using serial communication, or reading of the setting
value.
■
Temporary decoding of password 2 (read/write disable protection)
When password 2 protective status is shown and the same value as the password (hexadecimal 4 digits) set for
function code H99 is entered in H99, password 2 protective status is temporarily decoded and the function code
value can be read and it can be displayed on the touch panel.
If password 1 protection (rewrite disable protection) is also set, the function code can be rewritten by temporarily
decoding password 1 protective status continuously.
