6.2.2.5 Adjusting characteristics for analog input
Function description
If you change the analog input type using p0756, then the converter automatically selects the
appropriate scaling of the analog input. The linear scaling characteristic is defined using two
points (p0757, p0758) and (p0759, p0760). Parameters p0757 … p0760 are assigned to an
analog input via their index, e.g. parameters p0757[0] … p0760[0] belong to analog input 0.

You must define your own characteristic if none of the default types match your particular
application.
Example
The converter should convert a 6 mA … 12 mA signal into the value range ‑100% … 100% via
analog input 0. The wire-break monitoring of the converter should respond when 6 mA is fallen
below.
