| 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.
