Notes:
1. Maximum resolution presumes A3200 controller using MXH500 multiplication,
and accounts for controller quadrature.
2. Maximum speed based on stage capability. Maximum application
velocity may be limited by system data rate and system resolution.
3. Maximum loads are mutually exclusive.
4. All error motion specifications measured at 60 rpm.
5. To protect air bearing against under-pressure, an in-line pressure
switch tied to the motion controller is recommended.
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.
