Creating & Configuring Your Coordinate System Tag 181
Axis Grid
The Axis Grid is where you associate axes to the Coordinate System. There are
five columns in the Axis Grid that provide information about the axes in
relation to the Coordinate System.
[ ] (Brackets)
The Brackets column displays the indices in tag arrays used with the
current coordinate system. The tag arrays used in multi-axis coordinated
motion instructions map to axes using these indices.
Coordinate
The text in this column X1, X2, or X3 (depending on the entry to the
Dimension field) is used as a cross reference to the axes in the grid. For
a Cartesian system the mapping is simple.
Axis Name
The Axis Name column is a list of combo boxes (the number is
determined by the Dimension field) used to assign axes to the
coordinate system. The pulldown lists display all of the Base Tag axes
defined in the project. (Alias Tag axes do not display in the pull down
list.) They can be axes associated with the motion group, axes associated
with other coordinated systems, or axes from the Ungrouped Axes
folder. Select an axis from the pulldown list. The default is <none>. It is
possible to assign fewer axes to the coordinate system than the
Dimension field allows, however, you will receive a warning when you
verify the coordinate system and if left in that state, the instruction
generates a run-time error. You can only assign an axis once in a
coordinate system. Ungrouped axes also generate a runtime error.
Ellipsis Button (...)
The Ellipsis buttons in this column take you to the Axis Properties
pages for the axis listed in the row. See the “Creating and Configuring
Your Motion Axis” chapter in this manual for information about the
Axis Properties page.
Coordination Mode
The Coordination Mode column indicates the axes that are used in the
velocity vector calculations. Only Primary axes are used in these
calculations. Currently the only option is Primary. Therefore this
column is automatically filled in as Primary and cannot be edited.
