Special consideration must be given when programming these features:
Feature: Consideration:
Mirror Imaging Programmable mirror image is applied to all axes in the dual group. Manual
mirror image, however, can be applied to each axis in the dual group individually.
When manual mirroring is performed on selected axes in the dual group,
positioning commands are in effect reversed from the programmed commands to
the master axis. Manual mirror image is selected through PAL. Refer to the
documentation prepared by your system installer and page 12-79 for details.
Scaling When scaling, specify the scale factor for the master axis of the dual group. All
other axes in the dual group are then scaled using the master axis scale factor.
Refer to chapter 11 for details.
Digitizing When generating program blocks using digitize, park all but one axis of the dual
axis group. Use this unparked axis to generate the axis positions for the digitize
feature. The blocks created are stored using the master axis name. Refer to
chapter 5 for details.
Important: You can use the PAL axis mover feature if you want to
position dual axis group members separately without requiring any
parking. Refer to your PAL reference manual and the documentation
prepared by your system installer for details.
Invalid Operations on a Dual Axis
The following table contains a list of the features that are not compatible
with dual axes. You must execute one of these features on a dual axis, only
the AMP defined master axis can be used. All other axes in the dual group
must be parked. See the documentation prepared by your system installer
to determine master axis and slave axis names.
