Using know-how protection

Overview
Before activating know-how protection, the following conditions must be met:
● The drive unit has been fully commissioned.
● The OEM-exception list has been created
● The password is entered at the end.
● To guarantee know-how protection, you must ensure that the project isn't left with the
Creating the OEM exception list
Enter the parameters into this exception list that should still be able to be read and written in
spite of active know-how protection. The exception list can only be created via the expert list.
The exception list has no influence on the input screen forms in STARTER.
In p7763, define the required number of parameters of the exception list. You can enter a
maximum of 500 parameters in the exception list. In p7764[0...n], assign the required
parameter numbers to the individual indices of p7763. Finally, transfer the changes to the
Control Unit so that they can become effective.
Factory setting for the exception list:
● p7763 = 1 (exception list contains precisely one parameter)
● p7764[0] = 7766 (parameter number for entering the password)
Parameters of the exception list are not checked
The Control Unit does not check which parameters you include or delete in the exception
list.
Absolute know-how protection
By removing parameter p7766 from the exception list of p7764[0] = 0, you prevent any
access at all to the data of the Control Unit and your project settings. It is then impossible to
read or change the protected data. The know-how protection and the copy protection can no
longer be canceled or deactivated.

After setting the password, you must backup with "RAM to ROM", so that protection is
retained the next time the system is switched off.
