Generating an exception list for know-how protection

Using the exception list, as machine manufacturer you can make individual adjustable
parameters accessible to end users although know-how protection is active. You may define
the exception list via parameters p7763 and p7764 in the expert list. Specify the number of
parameters for the selection list in p7763. Assign the individual indexes to the parameter
numbers of the selection list in p7764.
Procedure
Proceed as follows to change the number of parameters for the selection list:
1. Save the inverter settings via an upload (
2. In the project on the PC, set p7763 to the desired value.
3. Save the project.
4. Go online and load the project into the inverter (
5. Now make the additional settings in p7764.
You have modified the number of parameters for the selection list.
Factory setting for the exception list:
● p7763 = 1 (selection list contains precisely one parameter)
● p7764[0] = 7766 (parameter number for entering the password)
Note
Block access to the inverter as a result of incomplete exception lists
If you remove p7766 from the exception list, you can no longer enter a password and
therefore no longer deactivate know-how protection.
In this case to access the inverter again, you have to reset the inverter to the factory
settings.
