Pre-shipment Inspection Record: This document details the visual and technical inspection of the Yaskawa SGMGH-20DCA6F-OY 2.0 kW Sigma-II Servo Motor Retrofit Guide. All product photos and testing videos below are original materials captured first-hand by the Koeed technical team in our warehouse prior to dispatch.

This guide covers the Yaskawa SGMGH-20DCA6F-OY, a 400 VAC class, 2.0 kW, 1500 min-1 medium-inertia Sigma-II rotary servo motor with a 130 mm frame, 12.7 Nm continuous torque, 31.8 Nm peak torque, and 17-bit serial feedback. It reviews drive pairing with the SGDH-20DE, 2026 IT/OT integration options, legacy versus modern benchmarking, TCO and ROI for exchange versus migration, common alarm-code troubleshooting, and predictive maintenance planning for machine builders and MRO teams. Key checks include verifying nameplate voltage, encoder compatibility, shaft and flange dimensions, brake option, oil seal, cable pinouts, and environmental ratings. For new designs, compare with Sigma-7 or Sigma-X servos for higher bandwidth and network-native EtherCAT support. For existing machines, a certified exchange or repair can preserve form-fit-function while improving lifecycle support. Always confirm torque-speed curves, regenerative energy, and drive capacitor condition before commissioning.
