3) Absolute pulse coder (APC) alarm
Number Message Contents
300 nthaxis origin return Manual reference position return is required for the nthaxis (n=1 8).
See Chapter 7.
301 APC alarm: nthaxis communication nthaxis (n=1 8) APC communication error. Failure in data
transmission
Possible causes include a faulty APC, cable, or servo amplifier.
302 APC alarm: nthaxis over time nthaxis (n=1 8) APC overtime error.
Failure in data transmission.
