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 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 parameters A1-01 to A1-03, or A2-01 to A2-32.
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).
