tromagnetic fields. Persons with implanted medical devices need to evaluate the risks
associated with these devices before they can enter an area where the devices are in use.
lStrong rare-earth magnets are present in the motor. Interaction with metallic objects
(tools, watches, or keys, for example) could produce pinch injuries or damage to the
equipment.
lUse non-magnetic tools when you do service to the motor.
DANGER: System travel can cause crush, shear, or pinch injuries. Restrict access to all
motor and stage parts while your system is connected to a power source.
lDo not put yourself in the travel path of machinery.
lMotors are capable of very high speeds and acceleration rates.

1.1. Environmental Specifications
WARNING: Do not expose this product to environments or conditions outside of the
listed specifications. You could damage the equipment if you exceed the environmental or
operating specifications.
Table 1-2: Environmental Specifications
Ambient
Temperature
Operating: 10° to 35° C (50° to 95° F)
The optimal operating temperature is 20° C ±2° C (68° F ±4° F). If at any time the
operating temperature deviates from 20° C degradation in performance could
occur.
Storage: 0° to 40° C (32° to 104° F) in original shipping packaging
Humidity Operating: 20% to 60% RH
Storage: 10% to 70% RH, non-condensing in original packaging.
The stage should be packaged with desiccant if it is to be stored for an extended
time.
Altitude Operating: 0 m to 2,000 m (0 ft to 6,562 ft) above sea level
Contact Aerotech if your specific application involves use above 2,000 m or below
sea level.
Vibration Use the system in a low vibration environment. Excessive floor or acoustical
vibration can affect system performance. Contact Aerotech for information
regarding your specific application.
Protection
Rating The ECO225SL stages have an ingress protection rating of IP10.
Use Indoor use only
1.2. Accuracy and Temperature Effects
The accuracy specification of ECO225SL series stages is measured 25 mm above the table with the stage
in an unloaded condition. The stage is assumed to be fully supported by a mounting surface meeting or
exceeding the specification in Section 2.3.
The accuracy of the screw is a key element in the overall positioning accuracy of the SLstage. A scale
error can be expected if temperature of the screw differs from 20° C (68° F). The greater the
temperature difference, the greater the error. The temperature of the screw depends on the speed and
duty cycle of the stage. The faster the movement and higher the duty cycle, the more the stage accuracy
will be affected by heat. The thermal expansion coefficient of the screw is 11.7 ppm/°C.

1.4. Vacuum Operation
There are two vacuum preparation options:
lLow Vacuum (for use in atmospheric pressures to 10-3 Torr)
lHigh Vacuum (preparation for environments from 10-3 to 10-6 Torr).
Special preparations include:
lParts are lubricated with vacuum-compatible lubricants.
lMaterials, fasteners, and coatings with vacuum outgas performance are ensured to be compatible
with the specified level of vacuum.
lFor high vacuum systems, situations that may allow gases to become temporarily trapped during
pump down are removed.
lPrior to assembly, stage parts are thoroughly cleaned in a clean environment.
lThe stage is packaged in a special polyethylene bag.
Vacuum Guidelines
To ensure that the stage will continue to perform well in the vacuum environment, follow the guidelines
listed below (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 for 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 oper-
ation 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. Bake vacuum components at 60 °C for 24 to 48 hours to significantly reduce outgassing at initial
pump-down to vacuum pressure and evaporate water vapor that impregnates porous surfaces on the
aluminum and Teflon cables. Aerotech recommends that customers bake out vacuum systems when
first installing them in the vacuum chamber. Contact Aerotech to discuss your application and the
recommended bakeout procedure.

Chapter 2: Installation
WARNING: ECO225SL installation must be in accordance to instructions provided by this
manual and any accompanying documentation. Failure to follow these instructions could
result in injury or damage to the equipment.
2.1. Unpacking and Handling the Stage
WARNING:HEAVY! It is the responsibility of the customer to safely and carefully lift and
move the ECO225SL.
lRefer to Section 1.3. for stage mass specifications. Do not attempt to lift heavy loads
single handed.
lUse care when you move the ECO225SL or you could negatively affect the performance
of it.
lLift this product only by the base.
lUse lifting hardware if it has been provided (refer to Figure 2-1).
lUse a cart, dolly, or similar device to move the stage to a new location.
lFor multi-axis assemblies, always lift the system by the lower axis.
lDo not use the cables or the connectors to lift or move this product.
lMake sure that all moving parts are secure before you move the ECO225SL. Unsecured
moving parts could shift and cause injury or damage to the equipment.
Carefully remove the stagefrom its protective shipping container. Gently set the stage on a smooth, flat,
and clean surface. Use compressed nitrogen or clean, dry, oil-free air to remove any dust or debris that
has collected during shipping.
Before you operate the stage, let it stabilize at room temperature for at least 12 hours. This will ensure
that all of the alignments, preloads, and tolerances are the same as they were when they were tested at
Aerotech.
Each stage has a label listing the system part number and serial number. These numbers contain
information necessary for maintenance or system hardware and software updates. Locate this label and
record the information for later reference.
ECO225SL Hardware Manual Chapter 2: Installation

Lifting Features
The lifting kit includes four eyebolts and four standoffs. Thread the eyebolts onto the standoffs and
thread the standoffs into the stage base. Remove the lifting hardware by turning a wrench on the flats
of the standoffs (see Figure 2-1). If the stage is part of a multi-axis system, the lifting hardware should be
attached to the lower axis. The lifting hardware must be removed before the stage can be operated.
