Q: What does Mazak alarm 818 mean?

Mazak alarm 818 is "MISSING CENTER (NO DATA) (WNo., NNo., BNo.)". For arc interpolation by R designation, the coordinates of the center of the arc cannot be calculated. Axis moving by manual interruption is specified in immediate front of the arc command. The arc cannot be defined since the relationship between the starting point, ending point, and radius of the arc becomes incorrect. Error type: Registered Data — program or tool data error.
