Rotary actuator DGII series

electricintegratedprecision

The DGII Series is a line of of products that combine a high rigidity hollow rotary table with an AlphaStep absolute encoder AZ series closed loop stepper motor and driver package. It retains the ease of use of a stepper motor, while also allowing for highly accurate positioning of large inertia loads. • Integrated actuator and stepper motor makes design easier • Easy Home Setting and Return-to-Home without need for sensors • Large-diameter hollow output table • Stepper motor provides excellent performance • Agile responsiveness • Stability at low speeds • Tuning-free High Positioning Accuracy • Non-Backlash • Repetitive Positioning Accuracy ±15 sec • Lost Motion 2 arc minutes Note: The repetitive positioning accuracy is measured at a constant temperature (normal temperature) under a constant load. Large-Diameter, Hollow Output Table Makes Simple Wiring and Piping Possible The large diameter hollow hole (through-hole) helps reduce the complexity of wiring and piping, thus simplifying your equipment design. The gear-reduction mechanism employs precision gears along with a proprietary adjustment mechanism that eliminates backlash. The repetitive positioning accuracy from a single direction is ±15 sec., while lost motion in a positioning operation from two directions is 2 arc minutes. These characteristics make the DGII series the ideal choice for applications in which accurate positioning is a must. The hollow output table is integrated with a high rigidity crossroller bearing*. The structure improves permissible thrust load and moment load while maintaining high torque.
