ABB ACS580 - Standard AI

166 Parameters
12
12 Standard AI
Configuration of standard analog inputs.
12.02 AI force selection The true readings of the analog inputs can be overridden for
eg. testing purposes. A forced value parameter is provided for
each analog input, and its value is applied whenever the
corresponding bit in this parameter is 1.
Note: AI filter times (parameters 12.16 AI1 filter time and
12.26 AI2 filter time) have no effect on forced AI values
(parameters 12.13 AI1 forced value and 12.23 AI2 forced
value).
Note: Boot and power cycle reset the force selections
(parameters 12.02 and 12.03).

12.03 AI supervision
function
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 12.04 AI supervision selection.
No action
No action No action taken. 0
Fault Drive trips on 80A0 AI supervision.1
Warning Drive generates an A8A0 AI supervision warning. 2
Last speed Drive generates a warning (A8A0 AI supervision) 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.
3
Speed ref safe Drive generates a warning (A8A0 AI supervision) 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.

12.04 AI supervision
selection
Specifies the analog input limits to be supervised. See
parameter 12.03 AI supervision function.

Bit Name Description
0 AI1 < MIN 1 = Minimum limit supervision of AI1 active.
1 AI1 > MAX 1 = Maximum limit supervision of AI1 active.
2 AI2 < MIN 1 = Minimum limit supervision of AI2 active.
3 AI2 > MAX 1 = Maximum limit supervision of AI2 active.
