Issue:
Looking to monitor or read the DC bus on the ATV61 drive HMI.

Product Line:
Altivar 61/71  ATV61 ATV71

Environment:
All

Cause:
Limited access to terminals

Resolution:
There are no monitoring options for reading the DC Bus from the drive HMI.
In the monitor menu it will display "Mains Voltage".
To calculate the DC Bus voltage:
If you multiply this value by 1.414 (sq root of 2) the result will be the value of the DC bus.
However, the drive does a calculation with the DC bus voltage to determine the mains voltage (line supply).
