Yaskawa SGDV-2R8A11A Sigma-V 400W 200V MECHATROLINK-II Servo Drive
Product Overview
The Yaskawa SGDV-2R8A11A is a Sigma-V series 400 W AC SERVOPACK equipped with a MECHATROLINK-II digital motion network interface. It is designed for synchronized single-axis control of compatible 200 V rotary servo motors within Yaskawa machine controller systems.
This model is not the same as the analog and pulse train SGDV-2R8A01A. The host controller, MECHATROLINK-II command set, network settings, communication cycle, station configuration, and controller project must be confirmed before replacement.
Main Features
- 400 W maximum applicable servo motor capacity
- Three-phase 200–230 VAC main circuit input
- 2.8 A continuous rated output current
- MECHATROLINK-II digital motion communication
- Single-axis synchronized network control
- 1.6 kHz speed frequency response
- Sigma-V high-resolution serial encoder feedback
- Integrated Safe Torque Off through HWBB
- Automatic tuning and vibration suppression

Compatible System and Applications
The SGDV-2R8A11A is intended for compatible Yaskawa Sigma-V 200 V rotary servo motors rated up to 400 W and a host controller that supports the required MECHATROLINK-II communication protocol. Verify the controller generation, transmission cycle, network cable, station address, and command compatibility.
Typical applications include synchronized packaging lines, electronic assembly equipment, semiconductor machinery, multi-axis positioning systems, printing equipment, material handling systems, and automated production machines.
Maintenance and Replacement Notes
Before replacing the SERVOPACK, record the original parameters, network station settings, MECHATROLINK-II configuration, controller project, firmware revision, and motor information. Confirm the complete SGDV-2R8A11A suffix, encoder type, brake, safety wiring, regenerative circuit, communication cable, motor cable, and feedback cable.
SGDV-2R8A01A uses analog and pulse commands, while SGDV-2R8A21A uses MECHATROLINK-III. Neither should be substituted for SGDV-2R8A11A without corresponding controller, network, cable, and project changes.
