F8 (All Drives): “A” Parameters Out of Spec.
Code Meaning: Internal memory used by the drive has lost data.
NOTE: An F8 code is common on many other types of devices (air conditioners, etc.). If you see an F8 code on a device that is not a Power Electronics Intl.® variable frequency drive, this F8 code description does not apply to your item.
Further Information/Troubleshooting Tips:
This code often indicates that at least one A parameter has accidentally been programmed in a way such that it is logically incompatible with other A parameter settings. Try reprogramming the “A” parameters individually or by performing a Gang-Set.
