Ultra Series Product Specifications
Linear Motor Ultra Stages utilize a non-contact optical encoder, integrated directly into the stage footprint. The encoder tape scale is mounted upside-down and referenced directly off the bearing surface, eliminating any abbe error and protecting it from any debris. The encoder read head is mounted inside the stationary base, eliminating moving wires.

(1) Maximum velocity is based on motor size and encoder resolution.
(1A) Maximum acceleration is load and motor size dependent. Actual acceleration may vary.
(2) Accuracy is based on a stage mounted to a flat granite surface and measured at 25mm above the center of the stage. Varies based on
encoder length. Repeatability is based on encoder resolution selected and above specification is for 0.1m resolution.
(3) Maximum and moment loads are based on bearing capacity. Loading will effect acceleration and velocity capability.
Specifications are subject to change without notice. Accuracy can be enhanced with mapping.

* Optional analog output head is available for use with external multipliers.
Tape scale pitch is 20 microns. Please contact factory.



Fx is the load applied in the Z Axis direction, 100mm off end, causing Mx rotation around the X Axis.

Fy is the load applied in the Z Axis direction, 100mm off side, causing My rotation aournd the Y Axis.

Fz is the load applied aournd the Z Axis at a 100mm from the center, causing Mz rotation around the Z Axis.
