Aerotech 的 ARA1000 旋转执行器代表了显著的突破性应用，如平板显示器处理加工所要求的大型有效载荷的联接方式。高负载惯量多轴系统可能遭受机械不稳定，限制整机生产效率。ARA1000 通过特殊设计，显著提高了平台刚性，消除了这个问题。ARA1000转台采用了标准的57.2毫米通孔，它可以很容易地穿过真空线路。台面包括一个标准的安装模式，其允许非常容易地进行卡盘安装。

1. Requires Aerotech controller for calibration and parts program implementation.
2. Based on Aerotech controls using 500X multiplication and controller quadrature. Higher resolutions available.
3. Maximum speed is load dependent. Maximum application velocity may be limited by system data rate and resolution.
4. To protect an air bearing against under pressure, an in-line pressure switch tied to the motion controller is recommended.
5. 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.
6. Specifications are for single-axis systems measured 25 mm above the tabletop. Performance of multi-axis systems is payload and workpoint dependent. Consult factory for multi-axis or non-standard applications.
