Operator input inhibit / parameterization inhibit
To prevent users from accidentally actuating the control keys and changing parameters, you
can activate an operator input / parameters disable using a key pushbutton. Two key icons
appear in the top right of the display when these inhibit functions are enabled.

The "Operator input inhibit" setting can be changed directly via <F5> "Change" once you
have selected the selection field.
When "Parameterization inhibit" is activated, you have to enter a numeric password (repeat
this entry). You must also enter this password when deactivating "Parameterization inhibit".
Operator input inhibit
(factory setting: not active)
●
Active
: The parameters can still be viewed, but a parameter value cannot be saved
(message: "Note: operator input inhibit active"). The OFF key (red) is enabled. The
LOCAL, REMOTE, ON (green), JOG, CW/CCW, INCREASE, and DECREASE keys are
disabled.
Parameterization inhibit
(factory setting: not active)
●
Active
: Parameters cannot be changed unless a password is entered. The
parameterization process is the same as with the operator input inhibit. If you try and
change parameters, the message "Note: Parameterization inhibit active" is displayed. All
the control keys can, however, still be actuated.
