1.4. Vacuum Operation
Vacuum option preparations are available as special orders. Contact Aerotech for more information.
There are two vacuum preparation options:

  • Low Vacuum (for use in atmospheric pressures to 10
  • High Vacuum (preparation for environments from 10 -3 Torr).

Special preparations include:

  • Parts are lubricated with vacuum-compatible lubricants. -3 Torr) to 10 -6
  • Materials, fasteners, and coatings are selected to be compatible with the specified level of vacuum.
  • High-vacuum systems are designed to eliminate trapped volumes.
  • Prior to assembly, stage parts are thoroughly cleaned in a clean environment.
  • The stage is packaged in a special polyethylene bag.

Vacuum Guidelines
To ensure that the stage will continue to perform well in the vacuum environment, use the guidelines that follow (in addition to standard handling, installation, and lubrication guidelines outlined in this manual).

  1. Do not remove the stage from its sealed bag until it is ready to use.
  2. Always handle the stage in a clean environment and use powder-free polyethylene gloves to prevent any contaminants from adhering to the surface of the stage.
  3. During installation, use cleaned, vented, stainless steel fasteners to secure the stage.
  4. Reduced air pressure eliminates significant convective heat transfer. This, coupled with the viscous vacuum-compatible lubricants, could result in excessive motor operating temperatures. Because of this, consider all continuous torque ratings to be 40 to 60% lower than the value specified for operation in normal atmospheric environment. Reduce motor usage accordingly.
  5. We recommend that you use a small quantity of Braycote® 602EF grease or a compatible substitute of equal quality lubricant in vacuum applications.
  6. To reduce outgassing during the initial pump-down to vacuum pressure, Aerotech recommends that you bake out vacuum systems when you first install them into the vacuum chamber. Bake the vacuum components at 60 °C for 24 to 48 hours to desorb water vapor from surfaces and degas polymers (such as cable insulation).

Installation

The stage installation must be in accordance with the instructions provided by this manual and any accompanying documentation. Failure to follow these instructions could result in injury or damage to the equipment.

2.2. Securing the Stage to the Mounting Surface
DANGER: Mechanical Hazard!

Personnel must be made aware of the mechanical hazards during set up or when you do service to the stage.

  • Do not manually move the stage if it is connected to a power source.
  • The stage must be mounted securely. Improper mounting can result in injury and damage to the equipment.
  • When you move the tabletop manually to do maintenance, this could expose the operator to pinch points. Refer to Pinch Points on Page 12.

The mounting surface must be flat and have adequate stiffness to achieve the maximum performance from the stage. When it is mounted to a non-flat surface, the stage can be distorted while the mounting screws are tightened. This distortion will decrease overall accuracy. Adjustments to the mounting surface must be done before the stage is secured.
Inspect the mounting surface for dirt or unwanted residue and clean if necessary. Use precision flatstones on the mounting surface to remove any burrs or high spots. Clean the mounting surface with a lint-free cloth and acetone or isopropyl alcohol and allow the cleaning solvent to completely dry. Gently place the stage on the mounting surface.
IMPORTANT: The stage is precision machined and verified for flatness at the factory.

  • Do not machine the stage housing. If you must machine a surface to achieve a required flatness, machine the mounting surface.
  • Keep the use of shims to a minimumwhen you mount the stage to the mounting surface. The use of shims could reduce the rigidity of the system.

Table 2-1: Stage Mounting Surface Flatness Requirement

Stage Flatness Requirement
All Frame Sizes 13 µm

ADRT series stages have a fixed mounting pattern available to secure the stage to a mounting surface. Figure 2-3 shows the main mounting holes in the base of the stage. Tightening torque values for the mounting hardware are dependent on the properties of the surface to which the stage is being mounted. Values provided in Table 2-2 are typical values and may not be accurate for your mounting surface. Refer to Section 2.1. for specific model mounting locations and dimensions.

2.3. Attaching the Payload or Fixturing 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. Gently place the stage on the mounting surface.
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 Chapter 3: Electrical Installation and the documentation delivered with the stage.
WARNING: General Hazard Warning!
Be careful when you attach the payload to the stage table.

  • Refer to the dimensions in Section 2.1. for maximum allowable thread engagement.

IMPORTANT: If your ADRT was purchased with Aerotech controls, it could have been tuned with a representative payload based on the information provided at the time of order. If you start the ADRT 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.
Table 2-3: Mounting Interface Flatness Requirement

Stage Travel Flatness Requirement
All Travels 13 µm

Applied loads should be symmetrically distributed whenever possible. The payload should be centered on the stage table and the entire stage should be centered on the support structure. Refer to Section 1.3. for maximum load carrying capacity specifications. If cantilevered loads are applied, refer to the Figure 2-5 to find the maximum allowable load.
IMPORTANT: Where possible, use 3-point mounting when you attach the payload to the stage.

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 3.2.). 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 3-2 shows the machine direction of ADRT stages.

Maintenance

IMPORTANT: Read the Safety Procedures and Warnings (on Page 8) before you do maintenance to the stage.

IMPORTANT: Keep the bearing area free of foreign matter and moisture or the performance and life expectancy of the stage will be reduced.
The ADRT series stages are designed to require minimum maintenance. In general, it is not possible for Aerotech field service personnel to repair or replace damaged or components that have malfunctioned. Repairs will typically require you to return the unit to the factory. Contact Aerotech Global Technical Support for more information.
4.1. Service and Inspection Schedule
Inspect the ADRT at least once per month. The need for a longer or shorter inspection interval will depend on the application and conditions, such as the duty cycle, speed, and environment.
Monthly inspections should include but not be limited to:

  • Visually inspect the stage and cables.
  • Re-tighten loose connectors.
  • Replace or repair damaged cables.
  • Clean the ADRT and any components and cables as needed.
  • Repair any damage before operating the ADRT.
  • Inspect and perform an operational check on all safeguards and protective devices.

4.2. Cleaning and Lubrication
DANGER: Electrical Shock Hazard! Before you do maintenance to the equipment, disconnect the electrical power.
IMPORTANT: Wear appropriate personal protective equipment (PPE) when you use cleaning solvents or lubricants.
In normal operating conditions and with proper cleanliness of the stage, the bearing will not require lubrication or maintenance for the life of the stage. The motor is completely non-contact and requires no lubrication under normal circumstances.
If the application process uses only a small portion of travel for most of the duty cycle, periodically drive the stage through full travel to redistribute the lubrication in the bearings.
When you clean components of the ADRT series stage:

  1. Use a clean, dry, soft, lint-free cloth.
  2. Before you use a cleaning solvent on any part of the stage, blow away small particles and dust with clean, dry, compressed air.
  3. In applications that have multiple stages bolted together to form multi-axis systems, the orthogonality can be lost if the stage tables of the support stages are loosened. Precision aligned stages should not be loosened or disassembled.
  4. We recommend that you do not disassemble the stage beyond the instructions given in this manual. Proper assembly and calibration can only be done at the factory. Contact Aerotech for more information.

Cleaning
Use isopropyl alcohol on a lint-free cloth to clean any external metal surface of the ADRT.
WARNING: General Hazard Warning! Make sure that all solvent has completely evaporated before you move the stage.

4.3. Travel Adjustment
WARNING: Mechanical Hazard! Do not adjust the optical limits to an angle greater than the hard stop travel. Doing so could result in damage to the stage and payload and the possibility of injury. Maintain at least±5° of overtravel between the optical limits and the hard stops.
Stages with the limited travel option have the optical limits and mechanical hard stops precisely set at the factory prior to shipment. The limit flag and table top are specifically designed for each travel option and cannot be adjusted to handle different travels. If you require a change in travel, contact Aerotech to purchase the correctly sized limit flag and table top.
