1.2. Accuracy and Temperature Effects

Aerotech products are designed for and built in a 20°C (68°F) environment. 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 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
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.

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
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.
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.
Use the system in a low vibration environment. Floor or acoustical vibration can
affect system performance. Contact Aerotech for information regarding your
specific application.
These stages have an ingress protection rating of IP10.
Indoor use only
