2-14 JC DIAG A1107 ROTATION CONTROL FAILURE
Diagnostic for:
112/005 error code (CAN code is 0x5025) correlation error
• Check the rotation motor and encoder cabling, and connections.
• Recalibrate the Rotation Board (see Job Card CAL A021 - Arm Rotation Calibration on page 1679). If
the ”Potentiometer out of range” error appears during the calibration, check the rotation potentiome-
ter. Change it if necessary (see Job Card D/R A227 - Rotation Potentiometer on page 1239), and
start the calibration again.
• If the rotation potentiometer unit is good and the error is still present, change the Rotation Board (Job
Card D/R A221 - Rotation Board on page 1223).
• If the error persists, change the rotation motor and encoder (see Job Card D/R A228 - Rotation Motor
on page 1243).

2-15 JC DIAG A1109 ROTATION CONTROL FAILURE
Diagnostic for:
112/010 error code (CAN code is 0x5004) optical fork error
• First check whether the optical fork has in fact been reached:
• If it has been reached, rotate the arm manually by moving the timing belt on the worm gear.
• Check for play in the gearbox and for tightness of the timing belt. Recalibrate the Rotation Board (see
Job Card CAL A021 - Arm Rotation Calibration on page 1679), and try the movement again.
• If the ”Potentiometer out of range” error appears during the calibration, check the potentiometer.
Change it if necessary (see Job Card D/R A227 - Rotation Potentiometer on page 1239), and start
the calibration again.
• If the problem is still present, change the Rotation Board (Job Card D/R A221 - Rotation Board on
page 1223).
• If optical fork is not reached:
- Check the optical fork cable and connections.
- If the cable and connections are good, change the optical fork.
• If the error persists, recalibrate the Rotation Board (see Job Card CAL A021 - Arm Rotation Calibra-
tion on page 1679).
• If the error persists, change the rotation motor and encoder cables (see Job Card D/R A228 - Rota-
tion Motor on page 1243).
