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
Operating: 10° to 35° C (50° to 95° F)
Temperature
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
The ANT95V-3 stages are not suited for dusty or wet environments. This equates to an
Rating
ingress protection rating of IP00.
Use
Indoor use only
1.2. Accuracy and Temperature Effects
Aerotech products are designed for and built in a 20°C (68°F) environment. Extreme temperature changes
could cause a decrease in performance or permanent damage to the ANT95V-3. At a minimum, the
environmental temperature must be controlled to within 0.25ºC per 24 hours to ensure the ANT95V-3
specifications are repeatable over an extended period of time. The severity of temperature effects on all
specifications depends on many different environmental conditions, including how the ANT95V-3 is
mounted. Contact the factory for more details.
The ANT95V-3 encoder scale is mounted on glass and measures the linear travel of the wedge. The thermal
expansion coefficient of the glass is 3.25 ppm/°C. Translated through the wedge angle of 7.70°, it becomes
an effective thermal expansion coefficient of 0.44 ppm/°C. As the temperature of the operating environment
changes from the temperature listed on the accuracy plot included with the stage, the accuracy of the stage
will change by 0.44 ppm/°C from the center of travel. For calibrated -PLUS stages, Aerotech controllers can
adjust the calibration based on the temperature of the environment. Contact Aerotech for more details.
The accuracy specification of ANT95V-3 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
