User lock
WARNING!
ABB will not be liable for damages or losses caused by the failure to activate
the user lock using a new pass code. See
For improved cybersecurity, it is highly recommended that you set a master pass
code to prevent, for example, the changing of parameter values and/or the loading
of firmware and other files.
With several drives, set a unique pass code for each drive.
To activate the user lock for the first time,
•
Enter the default pass code, 10000000, into 96.2. This will make parameters
96.100...96.102
•
Enter a new pass code into 96.100. Always use eight digits; if using Drive
Composer, finish with Enter.
•
Confirm the new pass code in 96.101.
WARNING!
Store the pass code in a safe place – the user lock cannot be opened even
by ABB if the pass code is lost.
•
In 96.102, define the actions that you want to prevent (we recommend you
select all the actions unless otherwise required by the application).
•
Enter an invalid (random) pass code into 96.2.
•
Activate 96.8, or cycle the power to the control unit.
•
Check that parameters
random pass code into 96.2.
To reopen the lock, enter your pass code into 96.2. This will again make parameters
96.100...96.102
visible.
