What is the ATV12 current threshold to trip on ground fault, SCF3?
Issue:
What is the ATV12 current threshold to trip on ground fault, SCF3?
Product Line:
Altivar 12
Environment:
All models
Cause:
NA
Resolution:
The threshold for an SCF3 fault is 25% of the nominal drive current. The fault appears when the vector sum of the output currents is greater than this level.
