ECO115SL Hardware Manual Overview
1.1. Environmental Specifications
W A R N I N G : Do not expose this product to environments or conditions outside of the listed
specifications. Exceeding environmental or operating specifications can cause damage to the
equipment.
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 ECO115SL stages have an ingress protection rating of IP10.
Use Indoor use only
1.2. Accuracy and Temperature Effects
The accuracy specification of ECO115SL 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.

Overview ECO115SL Hardware Manual
1.4. Vacuum Operation
Aerotech can specially prepare the ECO115SL for operation in vacuum environments. Aerotech offers two
vacuum preparation options; one for low vacuum (for use in atmospheric pressures to 10-3 torr) and one for
high vacuum (preparation for environments from 10-3 to 10-6 torr). As part of this preparation, attention to
detail during modification, cleaning, and assembly results in products with optimal performance in vacuum
applications.
Special Guidelines
To make sure that the ECO115SL 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 ECO115SL from its sealed bag until it is ready to use.
2. Always handle the ECO115SL in a clean environment and use powder-free polyethylene gloves to
prevent any contaminants from adhering to the surface of the ECO115SL.
3. During installation, use cleaned, vented, stainless steel fasteners when securing the ECO115SL.
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. For vacuum applications, the recommended lubricant is a small quantity of Braycote® 602EF grease or
a compatible substitute of equal quality.
6. Baking vacuum components between 100 and 125 °C for 24 to 48 hours significantly reduces
outgassing at initial pump-down to vacuum pressure and evaporates 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.

ECO115SL Hardware Manual Mechanical Specifications and Installation
Chapter 2: Installation
W A R N I N G : ECO115SL 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
D A N G E R / H E A V Y : It is the customer's responsibility to safely and carefully lift and move
the ECO115SL.
lLift only by the base.
lFor multi-axis assemblies, always lift the system by the lower axis.
lDo not use the tabletop or cables as lifting points.
lSecure all moving parts before lifting or moving the ECO115SL to a new location.
Unsecured moving parts could shift and cause bodily injury.
lImproper handling could adversely affect the performance of the ECO115SL. Use care
when moving the ECO115SL.
Carefully remove the ECO115SLfrom its protective shipping container. Gently set the ECO115SL on a
smooth, flat, and clean surface.
Before operating the ECO115SL, it is important to let it stabilize at room temperature for at least 12 hours.
Allowing it to stabilize to room temperature will ensure that all of the alignments, preloads, and tolerances are
the same as they were when tested at Aerotech. Use compressed nitrogen or clean, dry, oil-less air to
remove any dust or debris that has collected during shipping.
Each ECO115SL has a label listing the system part number and serial number. These numbers contain
information necessary for maintaining or updating system hardware and software. Locate this label and
record the information for later reference.

2.3. Securing the Stage to the Mounting Surface
W A R N I N G : The ECO115SL must be mounted securely. Improper mounting can result in
injury and damage to the equipment.
W A R N I N G : Make sure that all moving parts are secure before moving the ECO115SL.
Unsecured moving parts may shift and cause bodily injury.
D A N G E R : PINCHPOINT! Keep Hands Clear while the stage is in motion.
The mounting surface must be flat and have adequate stiffness to achieve the maximum performance from
the ECO115SL 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.
N O T E : The ECO115SL is precision machined and verified for flatness prior to product assembly at the
factory. If machining is required to achieve the desired flatness, it should be performed on the mounting
surface rather than the ECO115SL. Shimming should be avoided if possible. If shimming is required, it
should be minimized to retain maximum rigidity of the system.
Table 2-1: Stage Mounting Surface Flatness Requirement
Stage Travel Flatness Requirement
All Travels 7.5 µm
If necessary, manually move the stage table to access the mounting holes along the edges of the stage.
This stage is designed to use socket head cap screws (SHCS) to secure the base to the mounting surface.
N O T E : The stage table may offer a considerable amount of resistance when it is moved manually. This
is especially true if the stage is fitted with a motor assembly.
N O T E : If the stage is not connected to a power source, the stage should move freely by hand. Do not
attempt to manually move the stage if it is connected to a power source.
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 2.2. for specific model mounting locations and dimensions.

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 Chapter 3 and the documentation delivered with the stage.
N O T E : If your ECO115SL 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 ECO115SL 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 12 µm.
W A R N I N G : Refer to the dimensions in Section 2.2. for maximum allowable thread
engagement. A screw extending through the stage table can affect travel and damage the
stage.
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).
For a cantilevered load, first determine if it is a Vertical, Horizontal, or a Side cantilever system. Measure the
cantilever length, then find the corresponding load value from Figure 2-4.
The Vertical curve is for situations where the stage is mounted in a vertical orientation and the payload
is mounted to the table top with its center of gravity extended outward in a direction normal to the
tabletop surface. Refer to Figure 2-6 or Figure 2-7 for torque requirements on a vertical orientation.
The Horizontal curve assumes a horizontal stage orientation with the payload offset extending
outwards along the surface of the tabletop.
The Side curve is for situations where the stage is mounted on its side and the offset load extends
outwards in a direction normal to the tabletop surface.
Refer to Figure 2-5 for clarification on Vertical, Horizontal, or a Side orientations.
