Adapting the characteristic
You must define your own characteristic if none of the default types match your particular
application.
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.
Requirement
You have set analog input 0 as a current input ("I") via the DIP switch on the
Control Unit.

Set the following parameters to set the analog input as cur‐
rent input with monitoring:
1. set p0756[0] = 3
You have defined analog input 0 as current input with wire
break 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)
6. Set p0761[0] = 6
An input current < 6 mA results in fault F03505.
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.
