Dual Axes - two completely separate
axes
responding
to
the
same
programming commands.
Encoder
The control can support two dual axis groups. A dual axis group consists
of two or more axes coupled through AMP and commanded by a master
axis name. The master axis name is used by the part programmer or
operator when commanding the dual axis group in part programs or for jog
moves.
Each axis that makes up a dual group is controlled by a separate
positioning command from the servo module. This dual group command
is based on the move generated by the control when the master axis is
commanded to a position.
All axes that make up a dual group reach end-point at the same time.
This requires that all axes that make up a dual axis group share the same
feedrate parameters, acc/dec ramps, and other axes specific data for the
group.
This section requires that you understand the following terms:
Master Axis -- A master axis is the name used to command the axes in a
dual group.
Dual Group -- A dual group is a set of axes that are coupled together in
AMP and commanded by a single master axis name.
