[1]：The vertical-load of the center under the Horizontal-placement。

[2]：The  minimum motion increment is not the same as resolution,It means the minimum amount that a motion system can move in a continuous, stable situation. Generally, The resolution of the system is much smaller than the minimum motion increment. In consideration of the influence of transmission structure and the system error of the encoder, To compared with the linear motor Motorized drive Stages and the stepping motor Motorized drive Stages, The minimum motion increment of the linear motor Motorized drive Stages is more closer to the resolution.

[3]：The accuracy measurement data is the data measured by the laser interferometer when the platform is placed horizontally. The measurement standard reference to GB/T17421-2000

[4]：The difference between typical values and guaranteed values is described in the Technical Guide.

[5]：The maximum speed is typical values , on the basis of the difference of the load and the controller it would be Make a difference.
