Compatible System and Applications
The SGDH-15DE is intended for selected Yaskawa Sigma-II 400 V servo motors, including compatible SGMGH and SGMSH configurations. Applications include machine tools, printing machines, packaging lines, automated assembly equipment, industrial positioning axes, and material handling systems.
Compatibility depends on the complete drive and motor combination. Confirm the motor suffix, winding voltage, encoder type, brake option, controller command format, communication network, installed interface module, regenerative system, feedback cable, and motor power cable.
Maintenance and Replacement Notes
Back up the original SERVOPACK parameters before replacement. Verify that the required model is the standard SGDH-15DE and not SGDH-15DE-OY or another customized version. Compare the complete nameplate, firmware or hardware revision, connectors, and machine drawings.
Inspect the incoming power, grounding, regenerative resistor, motor connections, encoder cable, brake circuit, cooling condition, and external safety wiring. Confirm electronic gearing, rotation direction, limits, alarms, tuning settings, and mechanical travel during commissioning.
Related Models
Related models include SGDH-10DE, SGDH-15DE-OY, SGDH-20DE, and SGDH-30DE. Rated power, output current, suffix, system interface, motor matching, and firmware may differ between these models.
Inquiry and Supply Notes
Provide the complete nameplate information, hardware or firmware revision, controller model and project, communication or command network, motor model, encoder type, brake configuration, cable part numbers, installed modules, and parameter backup when requesting a quotation. Product condition and included accessories should be confirmed separately.
