Problem Reports
PR NumberTimesTime LostDescriptionResponse
413505:43-05:4300:00During down time we continued to try to cause faults in the tracker. After 3 positive x offsets of 60 I changed the focus down by 1.5(in 0.5 increments) then continued to move it back up by 1.5. The moving focus back up right after moving it down caused a master fault but no errors were given. Data should be in cycle 3. TT Camera was in closed loop.
414409:03-09:0900:06Commanded three -60 offsets in X without waiting for previous offsets to finish, just to see what would happen. Upon commanding a +60 offset in X a few seconds later the track aborted without triggering faults or displaying error codes. Occurred at the end of cycle 18. Upon attempting to go to next track tcs_server hung using 100% of CPU.
