Analog inputs
Overview
Changing the function of the analog
input
1.
Define the analog input type using
parameter p0756 to voltage input
0 V … 10 V.
2.
Specify the function of the analog
input by interconnecting parameter
p0755 with a connector input CI of
your choice.
Define the analog input type
The converter offers a series of default settings, which you can select using parameter
p0756:
AI 0 Unipolar voltage input
No sensor connected
0 V … +10 V
p0756[0] = 0
8
AI 1 Unipolar voltage inputt
No sensor connected
0 V … +10 V
p0756[1] = 0
8
If you change the analog input type using p0756, then the inverter automatically selects the
appropriate scaling of the analog input.
You can define your own characteristic that matches your particular application. The linear
scaling characteristic is defined using two points (p0757, p0758) and (p0759, p0760).
Parameters p0757 … p0760 are assigned to an analog input via their index, e.g. parameters
p0757[0] … p0760[0] belong to analog input 0.
