TroubleshootingGantry — Rotation driveTroubleshootingTroubleshoot
Troubleshoot the rotation section
Work this fault table against whatever the rotation section is actually doing — not rotating at all, whining or making noise, feeding an abnormal image while the rotation servo's overload relay trips, rattling covers, or slip-ring/brush trouble — to reach the OEM's probable cause and countermeasure for the Aquilion 16 gantry rotation drive (source Ch.4 §4.2, p.36-39).
Applies to
Aquilion 16 (TSX-101A)
Personnel
1 technician · Intermediate — electromechanical fault isolation (breaker/switch checks, connector reseating, cover fit-up, cable routing), with escalation to a Replace/Adjust procedure for the servo controller, motor, bearing, or rotation balance; several countermeasures explicitly say to call the Toshiba engineering personnel in charge instead of continuing the repair in the field (skill assessment derived from procedure content — not an OEM-stated skill level).
