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.

Signal smoothing
When required, you can smooth the signal, which you read-in via an analog input, using
parameter p0753.
For more information, please see the parameter list and the function block diagrams 2251 f
of the List Manual.

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

In order to use the analog input AI 0 as the source for
the supplementary setpoint, you have to set
p1075 = 755[0].
