Setting a Password
When a password is set in A1-05, if the set values in A1-04 and A1-05 do not match, you cannot refer to or
change the settings of constants A1-01 to A1-03, or A2-01 to A2-32.
You can prohibit the setting and referencing of all constants except A1-00 by using the password function in
combination with setting A1-01 to 0 (Monitor only).
