Is there any possibility to change AFE (Active Front End) DC voltage while it is connected to Altivar 71/61 drive.

The AFE is designed to work only together with Altivar 71/61 drives.
Therefore the AFE DC voltage is set automatically to the corresponding AC system which is:
380 - 400VAC ->650VDC
440AC        ->720VDC
500 - 525VAC ->840VDC
600VAC       ->960VDC
690VAC       ->1100VDC
An individual voltage setting is not implemented in the AFE.
