Absolute pulse coder, cable or servo module is faulty.
1 Agitate the absolute pulse coder cable connected to the main CPU
board. If an alarm is issued, replace the cable.
Series 16 main CPU board: JS1A to JS6A
Series 18 main CPU board: JS1A to JS6A
2 Agitate the absolute pulse coder cable connected to the option 2 board.
If an alarm is issued, replace the cable.
Series 16 option 2 board: JS1A–2 to JS6A–2
Series 18 option 2 board: JS1A–2 to JS4A–2
3 Replace the servo module.
Replace the module corresponding to the axis indicated by the alarm,
as shown in the figure below.Servo module specification:
