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.

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.
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.
Related models include SGDV-2R8A11B, SGDV-2R8A11B002000, SGDV-2R8A01A, SGDV-2R8A21A, SGDV-1R6A11A, and SGDV-5R5A11A. Verify the complete suffix, network interface, hardware revision, and installed controller system.
Please provide the full nameplate, hardware or firmware revision, controller model, controller project, MECHATROLINK-II network information, station settings, motor model, encoder type, brake option, cable part numbers, safety circuit requirements, parameter backup, and existing alarm information. Product condition and included components should be confirmed individually.
