1.
Define the analog output type using parameter
p0776 (e.g. voltage output -10 V … 10 V or
current output 4 mA … 20 mA).
2.
Interconnect parameter p0771 with a
connector output of your choice (e.g. the
actual speed).
Connector outputs are designated 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 mA … +20 mA
0 V … +10 V
+4 mA … +20 mA
p0776[1] =

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).
