WARNING! Store the pass code in a safe place – even ABB cannot open
the user lock if the pass code is lost.
• In
96.102 User lock functionality
, define the actions that you want to prevent
(ABB recommends to select all the actions unless otherwise required by the
application).
• Enter an invalid pass code into
96.02 Pass code
.
• Activate
96.08 Control board boot
, or cycle the power to the drive.
• Make sure that the parameters

are hidden. If they are not,
enter another random pass code into
96.02 Pass code
.
To reopen the lock, enter your pass code into
96.02 Pass code
. This will again
make parameters

 Sine filter support
With a sine filter connected to the output of the drive, the drive must use scalar
motor control mode, and limit the switching and output frequencies to
• prevent the drive from operating at filter resonance frequencies, and
• protect the filter from overheating.
When using ABB sine filters (available separately), this is done automatically
when you switch bit 1 of
95.15 Special HW settings
on.
Contact your local ABB representative before connecting a sine filter from
another manufacturer.

 Dead-band function
With the Dead-band function, you can freeze the AI reference for a defined area
(that is, dead-band) or ignore a low AI reference caused by possible
electromagnetic interference issues.
In voltage mode:
AI dead band value = 10V* AI dead band (
12.110
) * 0.01
In current mode:
AI dead band value = 20mA* AI dead band (
12.110
) * 0.01
