System Architecture & Signal Flow
The SGM-02U3B4L operates within a closed-loop servo system architecture:
- Controller (PLC/CNC/Motion Controller) → issues position/speed/torque commands via pulse train, analog ±10V, or MECHATROLINK-II/III fieldbus
- YASKAWA Servo Drive (SGDV/SGDH) → receives commands, closes current/velocity/position loops, outputs 3-phase PWM power
- SGM-02U3B4L Motor → converts electrical power to mechanical torque; encoder feeds position data back to drive
- Encoder Feedback Cable (500L) → returns incremental/absolute position data at high resolution to the servo drive
This architecture supports position loop bandwidths exceeding 1 kHz, enabling sub-micron positioning repeatability in precision applications.

Technical FAQ
Q: Is the SGM-02U3B4L compatible with SGDV-2R8A01A servo drive?
A: Yes. The SGDV-2R8A01A is rated for 200W motors and is the recommended pairing for this motor. Ensure parameter Pn000.1 is set correctly for encoder type.
Q: What is the difference between SGM-02U3B4L and SGM-02U314L?
A: The suffix characters indicate shaft type, brake, and encoder options. The “B” in position 7 typically denotes a specific shaft/key configuration. Contact us with your application requirements for exact cross-reference confirmation.
Q: Can this motor be used with a third-party servo drive?
A: While physically possible with appropriate wiring adapters, YASKAWA servo motors are optimized for YASKAWA drives. Third-party drive compatibility requires custom parameter tuning and is not guaranteed.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–4 weeks depending on sourcing channel. Contact us for real-time availability.
Q: Do you provide a test report or inspection certificate?
A: Yes, a basic inspection report is available upon request. Third-party testing certificates can be arranged for an additional fee.
