5.7.8 Operator Input Inhibit/Parameterization Inhibit

To prevent users from accidentally actuating the control keys and changing

parameters, you can activate an operator input / parameterization inhibit using a

key pushbutton. Two key icons appear in the top right of the display when these

inhibit functions are enabled.

Settings

Operator input inhibit (factory setting: no)

• Yes: The parameters can still be viewed, but a parameter value cannot be

saved (message in the status bar: "Operator input inhibit – parameterization

disabled"). The OFF key (red) is enabled. The LOCAL, REMOTE, ON (green),

JOG, CW/CCW, INCREASE, and DECREASE keys are disabled.

Parameterization inhibit (factory setting: no)

• Yes: 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 "Parameterization inhibit – no change

rights" is displayed in the status bar. All the control keys can, however, still be

actuated.

NOTE

If you have forgotten your password, you can switch off the parameterization inhibit

as follows:

1. Switch off the power supply

2. Disconnect the RS232 data cable

3. When switching the power supply back on, press the key pushbutton and hold

down for 20 s.

4. When the key symbol in the top right of the display disappears, the access

protection function has been reset.
