Troubleshooting

Overload error

Possible cause

Solution

Head lock up holding force exceeded during CMM acceleration

Reduce mass of probe combination.

Reduce acceleration.

Collision with workpiece or CMM

Check head for damage.

Remove obstruction and repeat move.

Obstruct error

Possible cause

Solution

Remove probe and reattach

Force applied to head during lock up

Lock and unlock the head

Incorrect lock up position

Reposition head correctly

Position not qualified

Check qualification information
