2-18 JC DIAG A1112 ROTATION BRAKE DEFECT
Diagnostic for:
112/008 error code (CAN code is 0x500D) brake error
•
Check the brake cable (W219) and connector (J6) visually, then check the DS 5 LED on the Rotation
Board:
-
It must be not lit in stop mode
-
It must be lit in rotation mode (the brake is active)
•
Power off the Gantry, and disconnect cable W19 from J6 of the Rotation Board, Measure the brake
resistance on the cable connector.
-
The nominal resistance value is 20 ohm +/-2 ohm. If the resistance is out of these limits, change
the brake (see
Job Card D/R A229 - Rotation Brake
).
-
If the measured resistance is acceptable, change the Rotation Board (

2-19 JC DIAG A1113 ROTATION CONTROL FAILURE
Diagnostic for:
112/011 error code (CAN code is 0x6004) overspeed error
•
Check the encoder cable (W205) and its connection (J9) on the Rotation Board.
•
If the cable is damaged, change the motor + encoder with cables (see
).
•
If J9 is damaged, change the Rotation Board (
Job Card D/R A221 - Rotation Board
•
If the cable is not damaged, and the connection is good, change the Rotation Board (
).
•
If the error persists, change the rotation motor+encoder unit with cables (see
).

•
Change the Rotation Board (
