Using a 9/Series Dual--processing System

The Dual Axis feature allows the part programmer to simultaneously
control multiple axes while programming commands for only one. It
differs from the split axis feature of the control in that the split axis feature
is used to control a single axis positioned by two servo motors.
The dual axis feature is especially useful for gantry mills with dual cutting
heads and other machines running with parallel cutting tools. Figure 19.1
shows a typical configuration for dual axes.

The 9/Series control supports two groups of dual axes. This is the total
number of groups allowed on the system for both processes (i.e. two
groups in one process or one group in each process).
Dual axis operation on dual processing systems is virtually identical to
dual axis operation on single processing systems (see chapter 20 for
details). The difference occurs on dual processing system when one or
more of the axes in the dual group is configured as a shared axis between
processes.
