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 Cybersecurity disclaimer (page 20).
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 visible.
• 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 96.100…96.102 are hidden. If they are not, enter another
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.
