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.
