Figure 19.2 shows the position display for a system that contains a dual
axis group containing two axes with a master axis name of X. Whether or
not all axes of a dual group show up on the position display is determined
in PAL by the system installer.

This feature allows the operator or programmer to disable selected axes of
the dual group. Any axis that is a member of a dual axis group can be
parked. Axes in the dual group may be parked simultaneously. If all axes
in the group are parked, no motion can take place in the dual axis group.
Once parked, no motion is allowed on the parked axis. Programmed and
jog commands (including any homing requests) made to the dual axis
group are ignored by the parked axes.
Axes in the dual group may be parked or unparked only when the control
is in cycle stop and end-of-block state. Also the control may not be in the
process of completing any jog request or PAL axis mover request. If an
attempt is made to park/unpark an axis and any one of the above
requirements is not true, the control ignores the request to park/unpark the
axis.
