MPS75SLE Hardware Manual

Electrical Specifications and Installation

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

3.5.

for Motor and Feedback phasing information). 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 3-3

shows the machine direction of MPS75SLE stages.
