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.

1Drive trips on 80A0 AI Supervision.Fault
2Drive generates an A8A0 AI Supervised Warning
warning.
Warning
3Drive 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
4Drive 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.

- / uint16(Visible when 14.1 Module 1 type = FAIO-01)
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.
