Parameters and firmware blocks
Current analogue input AI2 signal value is set as minimum value for
AI2, parameter
automatically.
Current analogue input AI2 signal value is set as maximum value for
AI2, parameter

13.13 AI SUPERVIS 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
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.
FW block: None
Supervision selected by parameter
AI1<min AI1 signal value falls below the value defined by equation:
