3.4. Limits, Marker, and Machine Direction
Aerotech stages are configured to have positive and negative "machine" directions. The machine
direction defines the phasing of the feedback and motor signals and is dictated by the stage wiring
(refer to
Section 3.2. ). Programming direction of a stage is set by the controller that is used to move
the stage. Programming direction is typically selectable in the controller, while machine direction is
hardwired in the stage.
Figure 3-5 shows the machine direction of APR100DR stages.
