Fagor alarm E250: Home search error
DDS drive display code (AXD/SPD/ACD/SCD seven-segment) · Fagor DDS drives
What it means
The drive could not complete the homing sequence executed under its own control. Fagor's listing simply directs to contact Fagor service; in practice verify the reference-mark feedback chain and homing-related parameters (e.g. NP166) before escalating. Related codes E253/E254 give more specific mark-detection failures.
Likely causes
- reference mark never seen due to feedback cable or encoder issues
- homing parameters inconsistent with mechanics (speed/window NP166)
- drive hardware fault in the mark-detection path
