Fig. 3.30 Start Axis Area
The following occurs if both axes are started and an error is
found in one:
1) both axes stop if the error has occurred between consecutive
positions.
2) only the axis with the error stops if the error occurred
after both axes have started.
(b) Data setting precautions
1) When both axes are to be started together (Le. interpolation
setting 00 or independent setting 1 1) ensure that the start
axis data matches for both X and Y axes at that point.
Processing will stop if the data does not match. Refer to Fig.
3.31.
