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.
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
delivered with the stage.
Applied loads should be symmetrically distributed whenever possible. For example, the payload should be
centered on the stage table and the entire stage should be centered on the support structure.
N O T E : If your ANT130LZ 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 ANT130LZ 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 1 µm per 50 mm.
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.
ANT130LZ Payload Mounting Steps:
1. Secure the ANT130LZ to the mounting surface (outlined in
2. Confirm that all electrical power is disconnected prior to making any mechanical adjustments. Do not
turn off air supply to system. Adjustments to the pneumatic pressure will be required in later steps.
3. Manually center the tabletop and reattach the shipping bracket using four M3 button head socket cap
screws.
4. Break free the two M3 button head screws that secure the shipping clamp to the tabletop. This will
allow the tabletop to fall a small amount.
5. Increase the air supply pressure until the tabletop starts to rise. Dial back the air supply pressure until
the tabletop is in equilibrium.
6. Remove the shipping bracket and verify that the tabletop is still in equilibrium. Adjust the air supply
pressure as required.
7. The system is now in balance.
8. Reconnect electrical power.
