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

Head / stylus configuration obstructed

Check head for damage
Remove obstruction and repeat move

Check emergency stop condition

Cable / connections faulty

Check condition of cabling from head to controller

No probe signal:

Possible cause

Solution

Probe incorrectly attached

Remove probe and reattach

Cable / connections faulty

Check condition of cabling from head to controller

Probe failure

Contact your Renishaw representative

Probe output disabled by CMM 

Check probe output

  
  

Poor measurement performance:

Possible cause

Solution

Loose head mounting

Ensure all mounting screws are tight and that mounting to the CMM is secure

Probe incorrectly attached

Remove probe and reattach

Stylus assembly incorrectly assembled

Check all components of the assembly and fully tighten with correct tools

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
