Adapting the characteristic
You must define your own characteristic if none of the default types match your particular
application.
Example
The inverter should convert a 6 mA ... 12 mA signal into the value range -100 % ... 100 %
via analog input 0. The wire break monitoring of the inverter should respond when 6 mA is
fallen below.
Precondition
You have set analog input 0 as a current input ("I") via the DIP switch on the
Control Unit.
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.

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)
