Procedure
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 based on its
index, e.g. parameter p0755[0] is assigned to analog input 0.

A complete list of the connector inputs is provided in the List Manual.

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.

Connector inputs (CI) of the inverter (selection)
Significance
Set the following parameters to set the analog input as
current input with monitoring:
1. Set p0756[0] = 3
This means that you define analog input 0 as current
input with wire breakage monitoring.
2. Set p0757[0] = 6.0 (x1)
3. Set p0758[0] = -100.0 (y1)
4. Set p0759[0] = 12.0 (x2)
5. Set p0760[0] = 100.0 (y2)

p2264 Technology controller actual value
To enter a supplementary setpoint via analog input AI 0,
you must interconnect AI 0 with the signal source for the
supplementary setpoint:
Set p1075 = 755[0].
