Overview ABL1500WB-B Hardware Manual
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: 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
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 ABL1500WB-B stages have limited protection against particles and dust. This equates
to 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 ABL1500WB-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 ABL1500WB-B is mounted. Contact the factory for more
details.
The -E1 and -E2 encoder scale in the ABL1500WB-B stage has a coefficient of thermal expansion (CTE) of
3.25 x 10
-6
/ °C. The -E3 encoder scale has a CTE of 7.5 x 10
-6
/ C. As the stage deviates from 20°C, travel
of the stage as seen by the encoder will change per the appropriate thermal expansion rate.
