6.3.2.8
Adjusting characteristics for analog output
Function description
If you change the analog output type, then the converter automatically selects the appropriate
scaling of the analog output. The linear scaling characteristic is defined using two points
(p0777, p0778) and (p0779, p0780).
Parameters p0777 ... p0780 are assigned to an analog output via their index, e.g. parameters
p0777[0] ... p0770[0] belong to analog output 0.
You must define your own characteristic if none of the default types match your particular
application.
Example
Via analog output 0, the converter should convert a signal in the value range 0% ... 100% into
an output signal 6 mA ... 12 mA.
Procedure
1. Set p0776[0] = 2
This defines analog output 0 as a current output.
2. Set p0777[0] = 0.0 (x1)
3. Set p0778[0] = 6.0 (y1)
4. Set p0779[0] = 100.0 (x2)
5. Set p0780[0] = 12.0 (y2)
The characteristic for the application example is set.
