Planar HD Series Stage User's Manual
Chapter 3: Operating Specifications
This chapter contains general technical information about Planar HD series stages. Included are basic prod-
uct specifications and general information on limit switches and motor wiring.
3.1. Environmental Specifications
The environmental specifications for the Planar HD are listed in the following table.
Table 3-1:
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 tem-
perature deviates from 20° C degradation in performance could occur. Contact Aerotech for
information regarding your specific application and environment.
Storage: 0° to 40° C (32° to 104° F) in original shipping packaging
Humidity
Operating: 40 percent to 50 percent RH
The optimal operating humidity is 50 percent RH.
Storage: 30 percent to 60 percent RH, non-condensing in original packaging
Altitude
Operating: 0 to 2,000 m (0 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
stage and system performance. Contact Aerotech for information regarding your specific appli-
cation.
Dust Expo-
The Planar HD stages are not suited for dusty or wet environments. This equates to an ingress
sure
protection rating of IP00.
Use
Indoor use only
Do not expose the stage to environments or conditions outside the specified range of oper-
ating environments. Operation in conditions other than those specified can cause damage to
the equipment.
3.2. Accuracy and Temperature Effects
The accuracy of the encoder scales are a key element in the overall positioning accuracy. In most stages, a
scale error can be expected if the temperature of the scale differs from 20° C (68° F); however, the Planar HD
is designed with encoder scales having vary small coefficients of thermal expansion (CTE). This feature
makes the accuracy of the stage much less dependent on the operating temperature. Although the accuracy
is much less sensitive to temperature than many systems, the best accuracy will still be achieved if the
stage is operated at the 20° C (68° F) temperature at which it was calibrated.
