What is an InF3 fault on an Altivar 12 drive?
All serial numbers for ATV12
Resolution: This is an internal issue with the drive. Power the drive down. Once the display is blank, power the drive back up. If the drive faults on InF3, a factory reset can be done by going to ConF menu and set FCS to InI (hold for 2 seconds). Power cycle the drive. If this does not fix the issue, it is recommended that the drive be replaced.
