Internal interconnection of the 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.

Adapting the internal interconnection of the analog input - Example
The inverter should receive the additional setpoint via
analog input AI
0. To do this, you must connect AI 0 with
the signal source for the supplementary setpoint.
Procedure
Proceed as follows to interconnect the analog input with the additional setpoint:
1.
Go online.
2.
Select "Inputs/outputs".
3.
Change the input function via the corresponding screen form.
1.
Go into the menu "PARAMS".
2.
As a parameter filter, select "EXPERT".
3.
Set p1075 = 755[0]
You have interconnected the analog input with the additional setpoint.
Advanced settings
Signal smoothing
When required, you can smooth the signal, which you read-in via an analog input, using
parameter p0753.
For more information, see the parameter list and in the function block diagrams 9566 ff of the
List Manual.
