To close the user lock, enter an invalid pass code into 96.02 Pass code , activate
96.08 Control board boot , or cycle the power. With the lock closed, parameters
96.100 … 96.102 are hidden.
To reopen the lock, enter your pass code into 96.02 Pass code . This will again make
parameters 96.102 … 96.102 visible.

Parameters 96.02 (page 355 ) and 96.100 … 96.102 (page 360 ).

Sine filter support
The control program has a setting that enables the use of ABB sine filters (available
separately). With a sine filter connected to the output of the drive, bit 1 of
95.01
Special HW settings must be switched on. The setting forces the drive to use the
scalar motor control mode, and limits the switching and output frequencies to
• prevent the drive from operating at filter resonance frequencies, and
• protect the filter from overheating.
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.
AI dead-band value = AI max ( 12.18 / 12.28 )

AI dead-band% ( 12.110 )
In addition, 10% of the dead-band value is added as dead-band hysteresis positive
and negative. This value is internally set in the firmware and cannot be changed.
Note: AI dead-band ( 12.110 ) is applicable for both AI1 and AI2.
