PH10 PLUS 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. |
Probe extension combination too long | Use a shorter / lighter stylus combination. |
Internal head fault | Contact your Renishaw representative. |
PH10 PLUS head and non-PLUS PHC10-3 or third party controller | Contact your Renishaw representative. |
Datum error
Possible cause | Solution |
|---|---|
Cable / connections faulty | Check condition of cabling from head to controller. |
Head / stylus configuration obstructed | Remove obstruction and update head using HCU2 or under CMM control. |
Probe extension combination too long | Use shorter / lighter stylus combination. |
Head damaged | Contact your Renishaw representative. |
No head movement in automatic mode
Possible cause | Solution |
|---|---|
Head controller in manual mode | Change to automatic mode. |
Power loss | Check mains cable connections and integrity. Check power block is supplying 24 V. Check CMM emergency stop condition - power may have been removed by CMM. |
Cable / connection fault | Check connection and integrity of cabling between head and controller. |
Communications failure | Check RS232 baud rate. |
Incorrect command set selected | Check correct command set is selected. |
PICS STOP is asserted by other system component | Clear the fault asserting PICS STOP. |
No head movement in manual mode
Possible cause | Solution |
|---|---|
Head controller in automatic mode. | Change to manual mode. |
Power loss | Check mains cable connections and integrity. Check power block is supplying 24 V. Check CMM emergency stop condition - power may have been removed by CMM. |
Cable / connection fault | Check connection and integrity of cabling between head and controller. |
No probe output signal received by the CMM computer
Possible cause | Solution |
|---|---|
Cable / connection fault | Check connection and integrity of cabling between head and controller. Check connection and integrity of cabling between controller and interface. Check connection and integrity of cabling between interface and computer. |
Multiwire bypass connector not fitted | Fit a multiwire bypass connector with will permit a standard touch-trigger probe signal to reach controller |
Multiwired probe in use | Check that the multiwire cable is correctly fitted to the head. Check that the trigger output to the CMM computer is connected to the multiwired probe interface. |
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 |
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 |
Probe damping enabled during measurement | Ensure probe damping is not enabled during measurement moves |
NOTE: Before seeking technical assistance, please make a note of the following information:
- Your CMM manufacturer and model
- The probe head model
- The probe head serial number
- The head controller serial number
- The head controller version number
- The LED sequence on the PHC10-3
- The stylus configuration fitted
If you experience problems that you are not able to identify or solve, please contact your Renishaw representative for further advice.
