Overview
MPS75SLE Hardware Manual
1.1. Environmental Specifications
W A R N I N G :
Do not expose the MPS75SLE
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. 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
The MPS75SLE 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 MPS75SLE series stages is measured 25 mm above the table with the stage
in a horizontal position. 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. 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.
