Procedure
Proceed as follows to change the number of parameters for the selection list:
1.
Save the inverter settings via an upload ( ) on the PC/PG and go offline ( ).
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.
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.
Replacing devices with active know-how protection
Replacing devices during know-how protection without copy protection
For know-how protection without copy protection, the inverter settings can be transferred to
another inverter using a memory card.
Replacing devices for know-how protection with copy protection
The know-how protection with copy protection prevents the inverter settings from being
copied and passed on. This function is predominantly used by machine manufacturers.
If know-how protection with copy protection is active, the Control Unit cannot be simply
replaced.
However, to allow the inverter to be replaced, you must use a Siemens memory card, and
the machine manufacturers must have an identical machine that they use as sample.
