ACT.
No action taken.
The drive trips on fault AI SUPERVISION.
The drive generates alarm AI SUPERVISION and sets the speed to
the speed defined by parameter
WARNING! Make sure that it is safe to continue operation in
case of a communication break.
The drive generates alarm AI SUPERVISION and freezes the speed
to the level the drive was operating at. The speed is determined by the
average speed over the previous 10 seconds.
WARNING! Make sure that it is safe to continue operation in
case of a communication break.
FW block: None
