Defining the analog input function
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.

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.
Specify deadband
Small signals of a few millivolts are often corrupted by interference in the cable. To be able
to enter a setpoint of exactly 0 V via an analog input, you must specify a deadband.

Parameters for the scaling characteristic and wire break monitoring
Description
x-coordinate of 1st characteristic point [V]
y coordinate of the 1st characteristic point [% of p200x]
p200x are the parameters of the reference variables, e.g. p2000 is the reference
speed.
x-coordinate of 2nd characteristic point [V]
y-coordinate of 2nd characteristic point [% of p200x]
Wire breakage monitoring response threshold
Connector inputs (CI) of the inverter (selection)
Significance CI Significance

p2253 Technology controller setpoint 1
p2264 Technology controller actual value
In order to use the analog input AI 0 as the source for
the supplementary setpoint, you have to set
p1075 = 755[0].
