15. At the Y-axis Servo Motor, the Rotary Encoder Cable, the black wire on Rotary Encoder Cable
should be orientated to Pin 1 labeled GND with the copper lead facing you.
16. Carefully remove the Servo Motor Connector (leads are fragile) and check for damage.
17. Are any of the Servo Motor leads damaged?
Go to Step 18
Servo Motor (P/N 62-1650-01) has failed. See
Parts Replacement section.
18. Check continuity of Rotary Encoder Cable (P/N 06-4535-00).
19. Does the Cable have continuity?
Rotary Encoder Cable (P/N 06-4535-00) has failed.
See
Parts Replacement section.
Go to Step 20
20. Check continuity of signal routing from the Y-axis Rotary Encoder as specified in Table 8-20.
