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
Operating: 16° to 25° C (61° to 77° F)
The optimal operating temperature is 20° C ±2° C (68° F ±4° F). If at any time the
Ambient
operating temperature deviates from 20° C degradation in performance could occur.
Temperature
Storage: 0° to 40° C (32° to 104° F) in original shipping packaging
Operating: 20% to 60% RH
Humidity
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
Altitude Contact Aerotech if your specific application involves use above 2,000 m or below sea
level.
Use the system in a low vibration environment. Excessive floor or acoustical vibration
Vibration can affect system performance. Contact Aerotech for information regarding your
specific application.
Protection ABL1500-B stages have limited protection against particles and dust. This equates to
Rating an ingress protection rating of IP50.
Use Indoor use only

1.2. Accuracy and Temperature Effects

Due to the small clearances in the air bearing design, extreme temperature environments could cause a
decrease in performance or permanent damage to the stage. Standard Aerotech air-bearing stages are
designed for and built in a 20°C (68°F) environment. The environmental temperature must be controlled to
within 0.25°C per 24 hours to ensure that the ABL1500-B 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 ABL1500-B is mounted. Contact the factory for more details.
The -E1 and -E2 encoder scale in the ABL1500-B stage has a coefficient of thermal expansion (CTE) of
-6
3.25 x 10 / °C. The -E3 encoder scale has a CTE of 7.5 x 10
of the stage as seen by the encoder will change per the appropriate thermal expansion rate.
