How does the Altivar 61 and Altivar 71 drives measure the line voltage parameter ( ULN ).
The measurement of the line voltage is done by the parameter ULN.
This value display come from the DC bus ,
ULN = Vbus/rootsquare (2)
The accuracy of the measurement depends of the state using drive
Accuracy with no load < 5%
Accuracy motor loaded is 10%~15%
