Hi Colin,

1) Look for pulse coder signals in Diagnose DGN 713,714,719
2) Check LSI chips MB8739AE(H) and their contacts on motherboard and ADD Axis card if present
3) Check pulse coder feedback cable and connection
4) Check parameters
5) Check servo/motor for wear and cable issues
Maybe this helps:
