Page 11: Controllers
Limits and Index Mark The A-141 series stage features non-contact limit switches and a home index marker. Both the limits and the index position are integral to the encoder electronics. The limits are magnetic and active high and are placed near the ends of travel. -
Page 12: Unpacking And Handling
Carefully unpack the air bearing stage and other components from the shipping packaging. Inspect the contents for signs of damage. If there is any sign of damage or missing parts, contact PI immediately. Compare the package contents to packing list and notify PI immediately if any parts are missing or incorrect. Keep all packaging materials in case the product needs to be returned. -
Page 13: Installation
The mounting surface should be flat and have adequate stiffness in order to achieve the maximum performance from the A-141. When the A-141 series stage is mounted to a non-flat surface, the stage can be distorted as the mounting screws are tightened. This distortion will decrease the overall accuracy of the stage. Adjustments to the mounting surface must be done before the stage is secured. -

By turning the main top/lift supply on or off while keeping the side/bottom supply on, the stage position can be locked. This can be done while a servo loop in enabled. Contact PI for more information about using this feature. -
Page 16: Affixing The Payload To The Stage
Do not exceed the maximum payload specified for the A-141 stage. Payload CG should not be cantilevered beyond the extents of the stage table. Page 16 of 25 PI (Physik Instrumente) L.P. 16 Albert Street, Auburn, MA 01501 Tel: 508-832-3456 Fax: 508-832-0506... -

Connecting the Cables Stage interconnect cables are not in the scope of delivery of the A-141 series stage. However, PI offers several standard cable sets that can be used, depending on the motion controller being used. Contact PI for a quote. -
Page 18: Startup And Operation Of The Stage
Note that the servo tuning values may need to be adjusted if the payload mass or size changes. If PI was not given user application information at the time of order, the servo was tuned with no (zero) payload mass. -
Page 19: Maintenance
User Manual A141D001 Rev 1.2 26-March-2020 Maintenance Other than basic cleaning, the A-141 series stage is maintenance-free. 8.1. Cleaning the Stage To clean the stage bearing surfaces, use isopropanol and a clean, lint-free cloth or wipe. Apply the cleaning agent to the cloth and wipe down all of the air bearing surfaces. When cleaning the air bearing it is recommended to leave the air supply turned on to help blow any particles out of the bearing and prevent particles from entering the nozzles. -
