Selects how the drive reacts when an analog input signal
moves out of the minimum and/or maximum limits specified
for the input.
The inputs and the limits to be observed are selected by
parameter 12.4 AI supervision selection.

Drive trips on 80A0 AI Supervision.
Fault
2
Drive generates an A8A0 AI Supervised Warning warning.
Warning
3
Drive generates a warning (A8A0 AI Supervised Warning)
and freezes the speed (or frequency) to the level the drive
was operating at. The speed/frequency is determined on
the basis of actual speed using 850 ms low-pass filtering.
WARNING!
Make sure that it is safe to continue operation in
case of a communication break.
Last speed
4
Drive generates a warning (A8A0 AI Supervised Warning)
and sets the speed to the speed defined by parameter
22.41 Speed ref safe (or 28.41 Frequency ref safe when
frequency reference is being used).
WARNING!
Make sure that it is safe to continue operation in
case of a communication break.

Specifies the analog input limits to be supervised. See
parameter 14.19 AI supervision function.
Note: The number of active bits in this parameter depends
on the number of inputs on the extension module.
