What level of current flow triggers an SCF2 fault on an ATV61 or ATV71 series drive?
Issue:
What level of current flow triggers an SCF2 fault on an ATV61/ATV71?
Product Line:
ATV61 / ATV71 series
Environment:
All models, All serial numbers
Cause:
Information not available in current literature.
Resolution:
SCF2
Principal :
The drive is protected against impedance (slow) short circuit, phase to phase or phase to ground on the output of the drive.
When there is a impedant short circuit the drive trips in SCF2 and the fault relay opens
Detection time:
It’s a software detection (a few ms). Output current sum > 25% of the rated current of the drive.
