What amount of current imbalance is needed for EPHO fault to be triggered on the ATV212 series drives?
Issue:
EPHO fault detected, what causes this?
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.
