Overview MPS75SL/SLE 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: 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.
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 spe-
cific application.
Protection
Rating The MPS75SL/SLE is 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
The accuracy specification of MPS75SL/SLE series stages 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
Section 2.3.
The accuracy of the screw is a key element in the overall positioning accuracy of the 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.
