Define the analog output type using parameter
p0776.
You define the analog output function by intercon‐
necting parameter p0771 with a connector output
CO of your choice.
Connector outputs are marked with "CO" in the parameter list of the List Manual.
Interconnecting signals in the converter (Page 447)
Define the analog output type
The inverter offers a series of default settings, which you can select using parameter p0776[0]:
Current output (factory setting)
0 mA … +20 mA
p0776[0] =
0
Voltage output
0 V … +10 V
1
Current output
+4 mA … +20 mA

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).

Examples for scaling characteristics
Parameters p0777 … p0780 are assigned to an analog output via their index, e.g. parameters
p0777[0] … p0770[0] belong to analog output 0.

Parameters for the scaling characteristic
Parameter
Description
p0777
x coordinate of the 1st characteristic point [% of p200x]
p200x are the parameters of the reference variables, e.g. p2000 is the reference speed.
p0778
y coordinate of the 1st characteristic point [V or mA]
