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 the keypad,
multi-function keypad, or external device using serial communication, or reading of the setting value.
Temporary disabling 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 keypad.
If password 1 protection (rewrite disable protection) is also set, the function code can be rewritten by temporarily
decoding password 1 protective status continuously.
