Prohibiting Writing Constants From The Digital Operator; Setting A Password - YASKAWA CIMR-F7A Instruction Manual

Prohibiting Writing Constants from the Digital Operator

If you set A1-01 to 0, you can refer to and set the A1 and A2 constant groups, and refer to drive mode, using
the Digital Operator.
If you set one of the constants H1-01 to H1-06 (multi-function contact input terminal S3 to S8 function selec-
tion) to 1B (write constants permitted), you can write constants from the digital operator when the terminal
that has been set is ON. When the set terminal is OFF, writing constants other than the frequency reference is
prohibited. You can, however, reference constants.

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).
