Fatal faults
Situations can occur that make it inadvisable or dangerous to continue using the CMM servo system. These are known in UCCsuite as fatal faults.
A list of UCC AI related fatal faults is shown below and will be indicated through the user's software (for example MODUS):
- A report of the emergency stop switch being active
- Air pressure is too low
- Crash switch operated, if fitted
- A scale reading failure
- An indicated overspeed (calculated from the rate of change of position)
- Outer limit switch active
NOTE: Other faults not classed as fatal can prevent the CMM's operation.
