UCC T3 controller troubleshooting
Fatal faults
The UCC T3 controller monitors a number of machine input / output signals and internal operational functions. If any of these reach a defined
level where the system believes it is dangerous to operate, a fatal fault will be applied.
When a fatal fault is detected it is not possible to engage the servo system. There may be other faults that prevent the CMM from engaging.
Not all are reported.
Reported fatal fault
Emergency stop
Air pressure
Crash
Scale failure
Overspeed
Over-temperature shutdown
The UCC T3 unit is designed for continuous power of up to 800 W. The unit will allow a supply current consumption of up to 12 A, which at
80 V is 960 W for a short period of time (1 second).
If this is sustained for a prolonged period, or the unit is not used in an adequate environment such as poor ventilation or high ambient
temperature, the unit will disengage the motors to protect itself. An over-temperature warning will be reported.
