Detailed Description SGDH-15AE-S-OY belongs to Yaskawa Σ-II (Sigma2) SGDH series servo amplifier. Rated power 1.5kW, single-phase AC200~230V input, rated input current 9.5A, output current 11.6A. The suffix S represents single-phase power version; OY stands for special customized variant. It supports pulse train or analog voltage speed/torque command from PLC or motion controller, can realize position, speed and torque three control modes, excellent low-speed smoothness and high dynamic response. Widely used for legacy CNC machine, packaging machinery, textile equipment and material handling positioning systems, matched with SGMPH, SGMG series Yaskawa servo motors.

This servo drive has standard CN1 I/O terminal for enable, alarm, positioning complete, overtravel signals; CN2 dedicated encoder interface receiving motor encoder feedback. Front digital LED display panel can show status codes, alarm codes and parameter values. Parameters can be set on panel or via JUSP-OP05 handheld operator. It supports electronic gear setting, positioning completion output, speed limit and torque limit function.

Full protection functions include overcurrent, overvoltage, undervoltage, overload, motor overheat, encoder fault, overtravel, servo overheat and main circuit abnormality alarm. Once fault triggers, servo cuts off power output and outputs relay alarm signal to protect motor and mechanical structure. IP20 protection grade for cabinet installation, operating temperature range 0~55℃, forced air cooling with built-in fan.

SGDH-15AE-S-OY is discontinued legacy Yaskawa Σ-II servo spare part. Many old automation machines still run with this servo system. When the original drive fails, replacing it with identical SGDH-15AE-S-OY can reuse existing servo motor, power cable, encoder wiring and original motion parameters. No major mechanical modification or program rewrite required. Technicians complete wiring connection, restore servo parameters and run JOG test, so the machine resumes operation quickly and reduces downtime.

Before shipment, every SGDH-15AE-S-OY undergoes comprehensive functional inspection including power-on boot test, I/O signal test, encoder feedback test, output waveform check, fan inspection and protection function simulation. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, parameter tuning and fault diagnosis. Fast global shipping is available for urgent maintenance orders.

For automation maintenance engineers and system integrators, SGDH-15AE-S-OY is reliable spare servo amplifier for legacy Yaskawa Σ-II motion control systems. It restores machine positioning accuracy and dynamic performance, extends service life of automation assets and avoids high-cost full mechanical & drive system renovation.
