Changing the function of an analog output:
1.
Define the analog output type using
parameter p0776.
2.
Interconnect parameter p0771 with a
connector output of your choice.

Connector outputs are marked with
"CO" in the parameter list of the List
Manual.
Defining the analog output type
The inverter offers a series of default settings, which you can select using parameter p0776:
AO 0 Current output (factory setting)
Voltage output
Current output
0 mA … +20 mA
0 V … +10 V
+4 mA … +20 mA
p0776[0] = 0

AO 1 Current output (factory setting)
Voltage output
Current output
0 mA … +20 mA
0 V … +10 V
+4 mA … +20 mA
p0776[1] = 0

Characteristics
If you change the analog output type, then the inverter automatically selects the appropriate
scaling of the analog output. The linear scaling characteristic is defined using two points
(p0777, p0778) and (p0779, p0780).
