Description

This parameter defines which halt group the axis is in. If any member of a halt group halts, all axes in that group will halt with the same halt type. Zero indicates that the axis is not a member of a halt group.

Sync Groups for synchronized axes have similar grouped halt functionality. Halts in any group will propagate recursively to other groups. If an axis halts, all axes in that group will halt, and so will the axes in any other sync group or halt group that the other axes are part of.

Why Bother?

For systems such as presses with 2 or more cylinders, where it is very important that the cylinders never get skewed, you typically want all the axes to halt when one axis halts. This parameter allows you to easily do that.
