Is there a way to determine the DC bus voltage from the display?

Issue:
How do you calculate the DC bus voltage using the "Mains Voltage" (ULn) displayed in the Monitor menu

Product Line:
ATV61, ATV71, ATV312, ATV12, ATV32

Environment:
All models and serial numbers

Cause:
None

Resolution:
These drives do a calculation using the measured DC bus voltage to estimate the mains voltage (line supply).  The drive measures the DC Bus internally and divides it by 1.414 (square root of 2) and then displays it as the Mains Voltage (ULn) In the monitor menu.

So, when given ULn, simply multiply by 1.414 to get the measured DC bus voltage value.
