Compatible System and Applications
The SGDH-08AE is intended for selected Yaskawa Sigma-II 200 V servo motors, including compatible SGMAH and SGMPH 750 W configurations. Typical applications include packaging equipment, pick-and-place systems, automated assembly lines, feeders, indexing tables, inspection equipment, and compact machine axes.
Confirm the complete motor model, rated voltage, encoder specification, brake option, controller project, analog or pulse command requirement, communication network, interface module, motor cable, and encoder cable before installation.
Maintenance and Replacement Notes
The standard SGDH-08AE uses a three-phase input, while SGDH-08AE-S is a single-phase version. These models should not be considered identical even when used with motors of similar capacity. Verify the complete suffix, nameplate, hardware or firmware revision, and machine power supply.
Back up the original parameters and isolate incoming power before servicing. Inspect grounding, terminals, regenerative components, motor and encoder cables, brake wiring, cooling passages, and external safety circuits. Verify direction, limits, alarms, electronic gearing, and tuning at reduced speed.
Related Models
Related models include SGDH-05AE, SGDH-08AE-S, SGDH-10AE, and SGDH-08AE-S-OY. Input phase, complete suffix, system configuration, firmware, and motor compatibility must be checked before substitution.
Inquiry and Supply Notes
Please provide the complete drive nameplate, hardware or firmware revision, controller model and project, command or communication network, motor model, encoder type, brake requirement, cable part numbers, installed modules, and original parameters. Product condition and included accessories should be confirmed before ordering.
