14.19 Machine Group-Based Alarm Stop
Usage example 3 for lathe
 When a number of machine groups are set in one part system:
When an alarm occurs at U1 axis of machine group 2, the axes in the group 1 are able to continue the operation although the
axes in the machine group 2 where the alarm occurred are stopped.
However, when an alarm occurred at the one of all axes to interpolate within one part system, all interpolated axes are
stopped regardless of the machine group setting.
