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.
Settings
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.
