关于线性串扰的注意事项：取决于安装载物台的表面的平整度。
最小增量运动注意事项：与系统稳定性（伺服抖动）直接相关;这取决于所使用的伺服驱动器。
关于定位精度的说明：校准精度只能通过控制器驱动的误差补偿来实现。必须通过 PI 的控制器订购载物台才能达到这些值。精度值假定持续时间较短，不考虑热漂移对载物台的长期影响。
关于 X 中允许推力的注意事项：该值适用于垂直安装
关于允许推力和力矩的注意事项：假设空气轴承的工作压力为 517 kPa （75 psi）。
工作压力说明：为保护载物台免受损坏，建议将气压传感器连接到控制器的急停输入端。
在 PI，技术数据规定为 22 ±3 °C。 除非另有说明，否则这些值适用于未加载的条件。某些属性是相互依赖的。名称 “typ.” 表示属性的统计平均值;它并不表示所供应的每件产品的保证价值。在产品的最终检验期间，仅分析选定的属性，而不是所有属性。请注意，某些产品特性可能会随着运行时间的增加而恶化。
