Anonymous Poster #1	Schneider Atv 630 SCF1 and SCF3 fault 09/23/2026 4:12 AM
	I have tried to reset the SCF1 and SCF3 faults on the Schneider Atv 630 to no avail. Even after following all the indicated processes from the manual, the alarm won't clear off. The motor windings are okay. The cable from VFD output to the motor is also okay. Is there any other remedy or I have to replace the drive?

	1. Is this a new installation? 2. How long has it been in operation? 3. What and when did you set the ground fault levels to for SCF3 4. Are you using shielded wire for your motor leads? 5. The fault will show up with the motor leads disconnected. Do you still have the fault?
