Prohibiting Writing Parameters from the Digital Operator
If you set A1-01 to 0, you can refer to and set the A1 and A2 parameter groups and refer to drive mode, using
the Digital Operator.
If you set one of the parameters H1-01 to H1-05 (multi-function contact input terminal S3 to S7 function
selection) to 1B (write parameters permitted), you can write parameters from the digital operator when the ter-
minal that has been set is ON. When the set terminal is OFF, writing parameters other than the frequency ref-
erence is prohibited. You can, however, reference parameters.
Setting a Password
When a pasword is set in A1-05, if the set values in A1-04 and A1-05 do not match, you can not refer or
change the settings of parameters A1-01 to A1-03.
You can prohibit the setting and referencing of all parameters except A1-00 by using the password function in
combination with setting A1-01 to 0 (Monitor only).
