Fagor alarm E808: Encoder not detected (with direct feedback)
DDS drive display code (AXD/SPD/ACD/SCD seven-segment) · Fagor DDS drives
What it means
No direct (second) feedback device responded at connector X3. Confirm the scale/external encoder is connected and undamaged and that GP10 matches the installed direct-feedback type. Sibling codes E809-E812 cover the communication, initialization, defect and mismatch variants on this input.
Likely causes
- direct feedback cable disconnected or broken
- linear scale head damaged or read gap lost after impact
- GP10 set for a different feedback class than installed
- X3 connector contamination/bent pins
