Gantry rotation system operation and troubleshooting (S/N Axxxxx)
Work the Aquilion 16 gantry rotation drive — from a normal power-up/rotate/stop sequence through a "Error in Gantry Rotation" message to one of 16 named servo-amplifier/KGTSM presumed-cause conditions — using the OEM's own operation description and fault-isolation steps for the **S/N Axxxxx** control configuration (source §7.6.1, p.118-128).
Applies to
Aquilion 16 (TSX-101A) — gantry rotation control, **S/N Axxxxx configuration only**. For the S/N Bxxxxx configuration, see the separate §7.6.2 atom (Related) — the two are not interchangeable in source.
Personnel
1 technician · Intermediate — electrical/electromechanical fault isolation on the rotation servo loop: oscilloscope checks (CN2, 5 VDC), continuity checks (MC121, TGR1, CNN119, FCS50/FCS51, F120/F121), DIP-switch confirmation (DSW12), and connector/cable checks — escalating to servo-amplifier, MR-sensor/PWB, or KGTSM PWB replacement when a countermeasure is exhausted. Several steps explicitly say to contact Nasu Operations instead of continuing the repair in the field (skill assessment derived from procedure content — not an OEM-stated skill level).
