What causes fault code PAL-005 (Palletizer Robot Teach Point Error)?

Robot encoder lost position after emergency stop or power loss. Teach pendant values accidentally modified. End-of-arm tool (EOAT) mounting shifted or damaged. Pallet or conveyor position changed — physical reference moved. Robot calibration data corrupted

How do I fix fault code PAL-005?

Home/master the robot to re-establish reference positions. Jog robot to known teach point and compare position data. Check EOAT mounting — tighten bolts, verify alignment. Verify pallet and conveyor positions haven't shifted. Re-teach affected points if positions have drifted. Back up teach data regularly to prevent loss

Palletizer Robot Teach Point Error

PAL-005

Robotic palletizer position data does not match expected coordinates. Teach points may have shifted.

Probable Causes (ranked)

Robot encoder lost position after emergency stop or power loss
Teach pendant values accidentally modified
End-of-arm tool (EOAT) mounting shifted or damaged
Pallet or conveyor position changed — physical reference moved
Robot calibration data corrupted

Fix Steps

1 Home/master the robot to re-establish reference positions
2 Jog robot to known teach point and compare position data
3 Check EOAT mounting — tighten bolts, verify alignment
4 Verify pallet and conveyor positions haven't shifted
5 Re-teach affected points if positions have drifted
6 Back up teach data regularly to prevent loss

Field Trick

Touch up ONE teach point (like the pallet corner) and run one cycle in slow mode. If it's off, all points shifted equally and you just need to re-master, not re-teach everything.
