System Configuration Diagram

♦   For detailed specifications, please read the description for the stage and connecting cable.

♦   For selection of driver, please refer to the cross-reference table for the motor/driver of the standard motorized stage or the GMT motor and driver catalog.

♦   The most preferred driver is recommended to be specified by GMT as considerations. For different needs, please choose the suitable driver based on real functional needs.

 

Axis Definition

GMT has defined different axis as the following figuration according to the movement direction:

Horizontal movement direction is X and Y axis.

Vertical movement direction is Z axis.

Movement around X, Y, Z axis is defined to α axis, β axis, and θ axis.

Green arrows present the specified axis movement direction.
