ILF fault on the ATV71 with an VW3A3501 CIC card installed.
All models, all serial numbers
If the CIC card is missing the external +24vdc pwr supply the drive will trigger an ILF fault after 1 sec of being powered up.
Per the CIC installation manual document, atv71_controller_inside_EN_V3 page 10, it is recommended to add an external power supply part number ABL7RE2402 to the controller inside cards +24vdc and com terminals to resolve issue.
