Issue:
Can the 0-10Vdc analog input be configured for 0-5Vdc?

Product Line:
Altivar 71

Environment:
All

Cause:
DC scaling 

Resolution:
Yes. There are scaling parameters for AI1 in menu 1.5 Inputs / Outputs that allow you to change the min and max values of the speed reference (UIL1 and UIH1 for AI1).  For a 0-5Vdc signal, UIL1 = 0 and UIH1 = 5.  Once these parameters are set, the speed reference is linearly scaled between them.
