Notes
1. Maximum speed based on stage capability; maximum application
velocity may be limited by system data rate and system resolution.
2. Per ANSI B89.3.4M, "Axes of rotation methods for specifying
and testing".
3. Consult Aerotech regarding error motions for the ABS2000 with
rotary union option.
4. Per ISO 1940, "Mechanical vibration - balancing quality
requirements of rigid rotors".
5. An in-line pressure switch tied to the motion controller is
recommended to protect the air bearing against under-pressure.
6. Air supply must be clean, dry to 0°F dew point, and filtered
to 0.25 µm or better. Recommend nitrogen at 99.9% purity.
