Parameter
p0779
p0780
Setting the characteristic
You must define your own characteristic if none of the default types match your particular
application.
Example:
Via analog output 0, the inverter should convert a signal in the value range 0 % ... 100 % into
an output signal 6 mA ... 12 mA.
Procedure
Defining the function of an analog output
You define the analog output function by interconnecting parameter p0771 with a connector
output of your choice. Parameter p0771 is assigned to the particular analog output via its index,
e.g. parameter p0771[0] is assigned to analog output 0.

6.3 Adapt the default setting of the terminal strip
Set the following parameters to set the characteristic to
match the example:
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)
