What is a Initialization Error (InFE) code on the Altivar 61/71 VFDs?
Resolution:
On the ATV61/ATV71, an Initialization Error (InFE) indicates an internal hardware initialization fault. An internal Schneider Electric support discussion also identifies the related display message“Ini.hard int.” as an internal hardware initialization fault.
For troubleshooting, check the control electronics and connections, particularly the ribbon cable between the control board and power board, and make sure it is properly seated. Low control-board voltage or a damaged control block are also possible causes mentioned in the support discussion
