Note
Absolute know-how protection
If parameter p7766 is removed from the exception list and know-how protection is activated,
then a password can no longer be entered. This means that know-how protection can no
longer be deactivated!
In this case, the drive can only be accessed by restoring the factory settings.

Loading data with know-how protection into the file system
Data with know-how protection can be directly loaded or saved to the file system from the
drive unit. The activated know-how protection ensures that the data cannot be forwarded to
unauthorized third parties.
The following end user applications are conceivable:
● Encrypted SINAMICS data must be adapted.
● The memory card is defective.
● The Control Unit of the drive is defective.
In these cases, the machine builder (OEM) can create a new encrypted subproject (for a
drive object) using STARTER. The serial number of a new memory card or a new Control
Unit is saved in this encrypted data set in advance.
Application example: Control Unit is defective
Scenario:
The Control Unit of the end user is defective.
The machine manufacturer (OEM) has the end user's STARTER project files of the machine.
Sequence:
1. The end user sends the OEM the serial numbers of the new Control Unit (r7758) and the
new memory card (r7843), and specifies the machine in which the Control Unit is
installed.
2. The OEM loads the STARTER project data of the end user.
3. The OEM initiates the STARTER function "Load to file system".
– The OEM specifies whether the data is to be stored zipped or unzipped.
– The OEM makes the settings required for know-how protection.
4. The OEM sends the stored data to the end user (e.g. by e-mail).
