Parameters 225
AI2 max tune Current analogue input AI1 signal value is set as
maximum value for AI1, parameter
13.02 AI1 MAX.
The value reverts back to No action automatically.
2
AI2 min tune Current analogue input AI2 signal value is set as
minimum value for AI2, parameter
13.08 AI2 MIN.
The value reverts back to No action automatically.
3
AI2 max tune Current analogue input AI2 signal value is set as
maximum value for AI2, parameter
13.07 AI2 MAX.
The value reverts back to No action automatically.

13.12 AI SUPERVISION
Selects how the drive reacts when analogue input
signal limit is reached. The limit is selected by
parameter
13.13 AI SUPERVIS ACT .
No / enum
No No action taken. 0
Fault The drive trips on fault AI SUPERVISION. 1
Spd ref safe The drive generates alarm AI SUPERVISION and
sets the speed.
WARNING! In case of a communication
break, make sure that it is safe to continue
operation.
2
Last speed 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! In case of a communication
break, make sure that it is safe to continue
operation.
