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.
