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