5.2 Write protection and know-how protection
In the factory setting, the exception list only includes the password for know-how protection.
You do not need to change the exception list, if, with exception of the password, you do not
require additional adjustable parameters in the exception list.
Factory setting for the exception list:
● p7763 = 1 (exception list contains precisely one parameter)
● p7764[0] = 7766 (parameter number for entering the password)
Note
Parameters belonging to the exception list can be viewed everywhere
All parameters in the exception list can be viewed in the web server and other commissioning
tools, even when know-how protection is activated.
Therefore, make sure that no critical parameters are entered in the exception list.
Absolute know-how protection
If you remove password p7766 from the exception list, it is no longer possible to enter or change
the password for know-how protection.
You must reset the drive unit to factory settings in order to regain access to the drive unit's
adjustable parameters. When restoring the factory settings, you lose what you have configured
in the drive unit, and you must recommission the drive unit.
