Two key icons appear in the top right of the display when these safety inhibits 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, HIGHER and LOWER keys are disabled.
Parameterization inhibit (factory setting: not active)
● Active: Parameters cannot be changed unless a password is entered. The
parameterization is the same as in the operator input inhibit state. If you try and change
parameters, the message: "Note: Parameterization inhibit active" is displayed. All the
control keys, however, can still be actuated.
