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.

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)

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].
