Engineering & Integration Guidance
When integrating or replacing the SGMAH-02AAA21 motor within an existing motion axis, adhere to these technical parameters:
- Drive Compatibility: Designed to pair seamlessly with Yaskawa Sigma-II SERVOPACK models such as the SGDH-02AE-OY (230V single/three-phase input). Verify that the amplifier firmware matches encoder requirements.
- Feedback Wiring: The 17-bit serial absolute/incremental encoder connects via the CN2 interface. Ensure shielded twisted-pair cables are properly grounded at both ends to prevent electrical noise interference in high-speed industrial environments.
- Mechanical Load Limits: The standard smooth shaft supports maximum radial loads up to 245 N and axial loads up to 74 N at the shaft end. Avoid exceeding these limits during mechanical coupling to prevent premature bearing wear.
- Verification: Always consult the official Yaskawa Sigma-II manual and verify drive parameter settings (such as electronic gear ratios and gain tuning) before enabling the axis.
Frequently Asked Questions
What does the “-02AAA21” suffix breakdown mean in this model code?
- SGMAH: Sigma-II medium-inertia, high-speed servo motor family
- 02: 200W power rating
- A: 200V power supply class
- A: 17-bit absolute / incremental serial encoder
- 21: Standard straight shaft design without a keyway (plus specific design revision options)
Can this motor operate with a 100V SERVOPACK?
No. The SGMAH-02AAA21 requires a 200V class amplifier (such as the SGDH-02AE) to achieve its specified torque and speed characteristics safely.
Is tuning required when replacing an existing motor?
If replacing an identical model on an existing axis with unchanged mechanical inertia, autotuning or parameter adjustments are usually minimal. However, running an online autotuning cycle via the SGDH amplifier or SigmaWin+ software is recommended to optimize loop stability.
