ECO225LM Hardware Manual
2.4. Attaching the Payload to the Stage
Inspect the mounting surface for dirt or unwanted residue and clean if necessary. Clean the mounting
surface with a lint free cloth and acetone or isopropyl alcohol and allow the cleaning solvent to completely
dry.
To prevent damage to the payload or stage, test the operation of the stage before the payload is attached.
Aerotech recommends that customers use a representative payload during start-up to prevent accidental
damage to the stage and the payload. Proceed with the electrical installation and test the motion control
system in accordance with the system documentation. Document all results for future reference. For
information on electrical installation refer to
N O T E : If your ECO225LM was purchased with Aerotech controls, it might have been tuned with a
representative payload based on the information provided at the time of order. If the ECO225LM is started
up without a payload, the servo gains provided by Aerotech with the shipment may not be appropriate and
servo instability can occur. Refer to the controller help file for tuning assistance.
The payload must be flat, rigid, and comparable to the stage in quality to maintain optimum performance.
N O T E : For valid system performance, the mounting interface should be flat within 12 µm.
W A R N I N G : Refer to the dimensions in
engagement. A screw extending through the stage table can affect travel and damage the
stage.
Applied loads should be symmetrically distributed whenever possible (i.e., the payload should be centered
on the stage table and the entire stage should be centered on the support structure).
For a cantilevered load, first determine if it is a Horizontal or a Side cantilever system. Measure the
cantilever length, then find the corresponding load value from
The Horizontal curve assumes a horizontal stage orientation with the payload offset extending
outwards along the surface of the tabletop.
The Side curve is for situations where the stage is mounted on its side and the offset load extends
outwards in a direction normal to the tabletop surface.
Refer to

for clarification on Horizontal or Side orientations.
