Mechanical Specifications and Installation
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 ANT130LZS 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 ANT130LZS 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 7.5 µm.
W A R N I N G : Refer to the counterbalance setup instructions if the payload on the stage is
changed.
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.
ANT130LZS Payload Mounting Steps:
1. Secure the ANT130LZS to the mounting surface (outlined in
2. Confirm that all electrical power is disconnected prior to making any mechanical adjustments.
3. Make sure the shipping clamp is removed from the stage.
4. Ensure the air pressure is balancing the tabletop at mid travel. Adjust the regulator as necessary.
5. With the air supply on, securely attach the shipping bracket to the stage.
6. Attach the payload to the stage.
7. Loosen but do not remove the two M3 button head screws that secure the shipping clamp to the
tabletop. This will allow the tabletop to fall a small amount.
8. Increase the air supply pressure until the tabletop starts to rise and then back it off until the stage
appears to be at equilibrium.
9. Completely remove the shipping clamp, and verify the stage is at equilibrium. Make adjustments as
necessary.
10. The system is now in balance.
11. Reconnect the electrical power.
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).
