Siemens has conducted a thorough investigation of the reported event.The incident was reconstructed based on the dmip logfile.For all segments, the isocentric and eccentric table positions are 0°.Based on these positions, the automatic motion protection feature considers the movement from segment 2 to segment 3 as safe and automatic gantry motion was allowed.It is also specified in the system user manual, when performing a dry-run, that the gantry will rotate counter clockwise if the travel distance is identical in both directions.Therefore, the system was operating according to specifications.
