System Configuration Diagram

♦ For selection of the drivers preferred, please refer to the reference table or the catalogue of Motor・Driver.

♦ All of the drivers chosed are the specification of GMT preferred. For different needs, please choose the suitable drivers according to 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.
