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.
Access level (standard factory setting):
The different parameters required for this complex application are filtered so that
they can be displayed as clearly as possible. You select them according to the
access level.
An expert level, which must only be used by expert personnel, is required for
certain actions. You need a password to activate this level. To activate expert
mode, enter code number "47".
The "Expert" access level is not stored permanently, which means that it must be
reactivated every time the power is switched on.
