SGDH-08AE-S is Yaskawa Sigma II series single-axis AC servo amplifier, rated for 0.75kW servo motor matching, with 200~230V AC single-phase or three-phase power input. It supports three standard control modes including position, speed and torque, receiving pulse-direction commands or ±10V analog signals from upper PLC or motion controller. Widely used in CNC machine tools, packaging machinery, automated assembly equipment and material handling systems. It is an end-of-life spare part for legacy Yaskawa Sigma II motion platforms.

This servo amplifier adopts cabinet wall mounting structure with IP20 protection class for installation inside control cabinets. Continuous output current reaches 5.7A and peak current hits 13.9A, with maximum output frequency of 300Hz to realize high-speed and smooth motor rotation. It is equipped with built-in regenerative braking circuit for rapid deceleration and stop. It automatically identifies matched Sigma II servo motors after wiring, and gain tuning function optimizes servo response and suppresses mechanical resonance. Digital I/O terminals and serial encoder interface realize closed-loop position feedback, ensuring high positioning accuracy.

Front panel digital display and operation keys support local parameter modification and fault code reading. Multiple LED indicators display power status, servo ready, alarm and encoder signals for rapid on-site troubleshooting. Configuration and backup can be completed via dedicated Yaskawa servo setup software. Built-in comprehensive protection functions cover overcurrent, overload, overvoltage, undervoltage, overheat, encoder disconnection and short-circuit protection to prevent hardware damage caused by abnormal power supply or load fluctuation. Operating temperature range is 0~55℃ for continuous stable operation in general industrial cabinet environments. Optional communication modules support Mechatrolink and other fieldbus networks.

SGDH-08AE-S is obsolete Yaskawa servo drive spare part. Many legacy automated production machines still adopt Sigma II servo systems. When the original amplifier fails, replacement with identical SGDH-08AE-S can reuse mounting holes, power cables, motor wiring and saved parameter settings. Technicians install the drive, complete auto-tuning and test jog and positioning motion, so the servo motion control system resumes operation and reduces production downtime.

Before shipment, every SGDH-08AE-S undergoes comprehensive functional inspection including power-on self-test, I/O signal test, encoder feedback verification and insulation resistance test. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, parameter setting and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, SGDH-08AE-S is reliable spare servo amplifier for legacy Yaskawa Sigma II motion control systems. It restores closed-loop single-axis high-precision positioning control, maintains machine motion performance, extends service life of automation assets and avoids whole mechanical axis renovation.
