The switch that belongs to the analog input is located behind the front door of the
converter.
The switch for AI 2 (temperature/current) is on the I/O Extension Module.
Defining the function of an analog input
You define the analog input function by interconnecting a connector input of your choice with
parameter p0755. Parameter p0755 is assigned to the particular analog input via its index, e.g.
parameter p0755[0] is assigned to analog input 0.
Connector inputs are designated in the parameter list with the prefix "CI".
Example
$,
U>@>@
S
In order to enter the supplementary setpoint via analog input AI 0, you must interconnect AI 0
with the signal source for the supplementary setpoint.
Set p1075 = 755[0].
