ABB ACS380 Series User Manual

Parameters 127
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.

12.11 AI1 actual value Displays the value of analog input AI1 in mA or V
(depending on whether the input is set to current or
voltage by a hardware setting).
This parameter is read-only.

Value of analog input AI1. 1000 = 1 unit
12.12 AI1 scaled value Displays the value of analog input AI1 after scaling. See
parameters 12.19 AI1 scaled at AI1 min and 12.20 AI1
scaled at AI1 max.
This parameter is read-only.

12.13 AI1 forced value Defines the forced value that can be used instead of the
true reading of the input. See parameter 12.02 AI force
selection.
