SGDV-2R8A15A belongs to Yaskawa Sigma‑5 (Σ‑V) high-performance servo family. Main power supply single-phase or three-phase AC200~230V, 50/60Hz. Continuous output current 2.8A, peak current 9.3A, suitable for 0.4kW linear servo motors. It adopts MECHATROLINK‑II real-time bus command interface instead of pulse/analog command, supporting high-speed synchronous multi-axis control with transmission speed up to 10Mbps.

This servo amplifier integrates adaptive auto-tuning function, mechanical resonance suppression and vibration suppression algorithm, speed response bandwidth up to 1600Hz, realizing fast positioning and low settling time. It has built-in STO safe torque off safety function. Digital I/O terminals support servo enable, alarm output, positioning completion, positive/negative overtravel limit signals. Parameter backup, gain tuning and fault diagnosis can be realized via SigmaWin+ software. External regenerative resistor can be connected for high deceleration applications.

Comprehensive protection functions include overcurrent, overload, overvoltage, undervoltage, drive overtemperature, encoder fault, short-circuit and earth fault protection. IP20 protection grade for cabinet mounting, operating temperature 0~55℃.

SGDV-2R8A15A is discontinued legacy Yaskawa servo spare part. Many old precision automation machines still adopt Sigma5 MECHATROLINK-II servo systems. When the original drive fails, replacing it with identical SGDV-2R8A15A can reuse matched linear servo motor, power cable, encoder wiring and original servo parameters. Technicians complete wiring, parameter restore and JOG test, so the machine positioning axis resumes operation and reduces downtime.

Before shipment, every SGDV-2R8A15A undergoes comprehensive functional inspection including power-on self-test, I/O signal test, encoder feedback test, MECHATROLINK-II communication test, output waveform check and protection function simulation. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, servo parameter tuning and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, SGDV-2R8A15A is reliable spare MECHATROLINK-II servo amplifier for legacy Yaskawa Sigma‑5 motion systems. It restores high-precision linear motor positioning and multi-axis bus synchronous performance, extends service life of automation assets and avoids high-cost whole motion system renovation.
