ABB ACS880-104

Parameters 197
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.

0000b…1111b Activation of analog input supervision. 1 = 1
12.05 AI supervision force Activates analog input supervision separately for each control
location (see section Local control vs. external control on
page 24).
The parameter is primarily intended for analog input
supervision when the input is connected to the application
program and not selected as a control source by drive
parameters.

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.
