1.1. Environmental Specifications
WARNING
:
General Hazard 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.
DANGER
:
Risk of Explosive Atmosphere!
l
Standard Aerotech stage/motors are not rated for applications with explosive
atmospheres such as air-born dust or combustible vapors.
l
Do not operate stage/motors outside of Aerotech environmental 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
These stages are not suited for dusty or wet environments. This equates to an
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 stage. At a minimum,
the environmental temperature must be controlled to within 0.25ºC per 24 hours to ensure the stage
specifications are repeatable over an extended period of time. The severity of temperature effects
on all specifications depends on many different environmental conditions, which include how the
stage is mounted. Contact the factory for more details.
The thermal expansion coefficient of the encoder scale is 3.25 ppm/°C. Travel will increase or
decrease at this rate as the temperature of the encoder scale temperature deviates from 20°C (68°F).
The accuracy specification of stage 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
