Issue:
EPHO fault detected, what causes this?

Product Line:
ATV212 series drives.  Open style and Enclosed versions.

Environment:
All models, All serial numbers.

Cause:
Information unavailable in current literature.

Resolution:
When the current draw on any phase drops to 25% or less of the load current and remains 25% or below for 90 degrees of rotation within the phase, EPHO fault is triggered.  This fault detection is designed to detect a load imbalance or an open phase(s) on the output of the drive and stop the drive.
