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

). 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.

shows the machine direction of ECO225SL stages.
