There are many different functions that you can assign to the analog output. These are identified
using the “CO” abbreviation in the parameter list. These parameters are typically signals such as
setpoints, frequencies or currents. They are converted from their digital form, scaled as you need and
then applied in 0-20mA form on the analog output.
For a full list of the “CO” parameters, please consult the parameter list.

Figure 5-13 – Analog Output Function Diagram
Figure 5-13 above shows how you connect the function that you want to see, to the AOUT (D/A
converter). There is a user definable filter (P0773) to smooth the signal, and you have the opportunity
to scale the output to suit your application using P0777-P0781. You get the output on the AOUT
terminals (0-20mA). If you want voltage instead of current, you can put a 500 Ohm resistor across the
output and for a 0-10V output.
