DualAxis Operation
Chapter 19

Special consideration must be given when programming the following
features:
Feature: Consideration:
MirrorImaging Programmable mirrorimageis applied to allaxesin the dualgroup. Manual
mirrorimage,however,canbe appliedtoeach axis in the dualgroup individually.

systeminstaller’s documentation andchapter14fordetails.
Scaling When scaling,specify the scale factorforthemasteraxisofthedual group. All
other axesinthedual group are then scaled usingthemasteraxisscalefactor.

Important: The PAL axis mover feature can be used if it is necessary to
position dual axis group members separately without requiring any
parking. Refer t o your PAL reference manual for more information.
Invalid Operations on a Dual Axis
The following table contains a list of the features that are not compatible
with dual axes. If it is necessary to execute one of these features on a dual
axis, only the AMP master axis may be used. All other axes in the
dual
group must be parked
. Refer to your system installer’s documentation to
determine which axis has been assigned in AMP as the master axis.
