5-2. Servo/DT System Check Mode

a) S REEL FG/MOTOR CHECK Checks the duty cycle of the S reel FG. In case of NG; Check the S reel motor (C010: S REEL MOTOR). If no abnormality is found, adjust the duty cycle of the S reel FG (A001: S REEL FG DUTY). b) T REEL FG/MOTOR CHECK Checks the duty cycle of the T reel FG. In case of NG; Check the T reel motor (C011: T REEL MOTOR). If no abnormality is found, adjust the duty cycle of the T reel FG (A002: T REEL FG DUTY). c) CAPSTAN FG/MOTOR CHECK Checks the duty cycle of the capstan FG. In case of NG; Check the capstan motor (C014: CAPSTAN MOTOR). If no abnormality is found, adjust the duty cycle of the capstan FG (A003: CAPSTAN FG DUTY). d) S REEL OFFSET/FRICTION Checks the offset and friction levels of the S reel. In case of NG; Check the S reel motor (C010: S REEL MOTOR). If no abnormality is found, adjust the offset and friction of the S reel (A004: S REEL OFFSET/FRIC). e) T REEL OFFSET/FRICTION Checks the offset and friction levels of the T reel. In case of NG; Check the T reel motor (C011: T REEL MOTOR). If no abnormality is found, adjust the offset and friction of the T reel (A005: T REEL OFFSET/FRIC). f) S REEL MOTOR TORQUE Checks the torque of the S reel. In case of NG; Check the S reel motor (C010: S REEL MOTOR). If no abnormality is found, adjust the torque of the S reel (A006: S REEL TORQUE). g) T REEL MOTOR TORQUE Checks the torque of the T reel. In case of NG; Check the T reel motor (C011: T REEL MOTOR). If no abnormality is found, adjust the torque of the T reel (A007: T REEL TORQUE).
