4.9 SYSTEM – Manual Configuration – Gantries (Secondary
Positioners)
This section is for experienced users of the XPS controller and addresses the
configuration of a gantry via a secondary positioner.
A gantry is a motion device where two positioners, each of them having a motor, an
encoder, limits, etc., are used for a motion in one direction. Like most gantries, the two
positioners are rigidly attached to each other, see example below. Hence, all motions,
including motor initialization, homing, and emergency stops must be done in perfect
synchronization.
Figure 16: Example of a gantry.
The XPS controller allows configuring single axis gantries (Xx configuration) and XY
gantries. For XY gantries, it is possible to define XxY, XYy and XxYy configurations.
Here, X and Y refer to the primary positioner and x and y to an assigned secondary
positioner.
To define a gantry, check the box “Use a secondary positioner” during the definition of
a Single Axis group or XY group. See chapter 4.8 for further instructions on how to
define a new motion group. When done, the following screen appears (example Single
Axis group):
