9.5 Write and know-how protection
Inverter with CU230P-2 Control Units
340 Operating Instructions, 11/2013, FW V4.6.6, A5E02430659B AG
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.
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
-activate 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 converter settings can be transferred to
another converter using a memory card.

● Transferring the setting from the memory card (Page 327)
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 inverter cannot be replaced as
described in "Replace Control Unit (Page 345)".
However, to allow the inverter to be replaced, you must use a Siemens memory card, and
the machine manufacturer must have an identical machine that he uses as sample.
