Sigma-V Series High Performance

The Sigma-V series represents Yaskawa's advanced servo system technology, offering high performance with improved processing speed compared to previous generations. The SGDV-2R8A11A achieves CPU computation time of 1/2 that of original products, with positioning time shortened to 1/3 through expanded control algorithms. The high-resolution 20-bit serial encoder provides precise feedback for smooth operation at low speeds and accurate positioning. The drive is designed for continuous duty with Class F insulation, ensuring reliability in demanding industrial environments.

MECHATROLINK-II Communication

The SGDV-2R8A11A supports MECHATROLINK-II communication, a high-speed real-time motion control network that enables coordinated multi-axis operation. The communication command type interface allows the drive to receive position, speed, and torque commands from a motion controller while transmitting status information for monitoring and diagnostics. The MECHATROLINK-II network supports up to 30 physical axes, providing scalable solutions for complex motion systems requiring synchronized control of multiple servo axes.

High-Resolution Feedback and Precision Control

The 20-bit absolute encoder provides 1,048,576 pulses per revolution resolution, enabling ultra-smooth operation and precise positioning even at low speeds. The absolute encoder eliminates the need for homing after power-up, providing immediate position information and reducing cycle times. The permanent magnet excitation mode and Class F insulation ensure efficient operation and long motor life. The IP67 protection rating (excluding shaft through part) provides resistance to dust and moisture, making the drive suitable for harsh industrial environments including machine tool applications with coolant exposure.

Compact and Rugged Design

The SGDV-2R8A11A features a compact design that saves panel space while delivering high power density. The fully enclosed self-cooling type with IP67 protection eliminates the need for external fans in many applications, reducing maintenance requirements and improving reliability. The drive is designed to withstand vibration level V15, ensuring stable operation in machinery with significant mechanical shock. The complete separation of the main circuit and control circuit allows alarms to turn off only the main circuit power supply, simplifying maintenance and troubleshooting.

Industrial Applications

The Yaskawa SGDV-2R8A11A servo drive is deployed across a wide range of industrial motion control applications. In machine tool feeding, it provides precise axis positioning for milling, turning, and grinding operations. In transport machinery, it controls conveyor drives and material handling systems. In handling machinery, it powers robotic arms and pick-and-place equipment. In food processing machinery, it provides reliable motion control for cutting, filling, and packaging equipment. The drive's combination of 0.45 kW power, 20-bit encoder resolution, and MECHATROLINK-II communication makes it suitable for applications requiring precise, coordinated motion control.

Conclusion

The Yaskawa SGDV-2R8A11A Sigma-V series servo drive delivers 0.45 kW with MECHATROLINK-II communication, 20-bit absolute encoder, and AC400V operation.
