- IP67 Sealing: Shaft-end seal and connector sealing allow operation in wash-down and coolant-splash environments without additional enclosures.
- Plug-and-Play with Sigma-II Drives: Auto-tuning and one-parameter setup via SGDH drives eliminates lengthy commissioning; encoder data is read automatically.
- Long Service Life: Precision ball bearings rated for >30,000 hours MTBF under rated load conditions.
- Compact Footprint: 40 mm flange fits space-constrained machine designs without sacrificing torque output.
System Architecture & Signal Flow
The USAHEM-01-TL31 operates within a closed-loop servo system architecture:
- Controller (PLC/CNC/Motion Controller) → issues position/speed/torque commands via pulse-train, analog ±10 V, or MECHATROLINK-II fieldbus to the SGDH servo drive.
- SGDH Servo Drive → performs current-loop control at 16 kHz switching frequency, outputs 3-phase PWM power to the motor stator windings.
- USAHEM-01-TL31 Motor → converts electrical energy to mechanical torque; encoder feedback (A/B/Z differential signals) returns position data to the drive at 2,048 P/R.
- Encoder Feedback Loop → drive closes position and velocity loops in real time, achieving position accuracy of ±1 encoder pulse (≈0.044°).
Wiring: Power connector (MS3102A18-10P or equivalent) + encoder connector (MS3102A20-29P). Shielded encoder cable (YASKAWA JZSP-CMP00-xx) is strongly recommended to maintain signal integrity over distances up to 20 m.

Technical FAQ
Q: Is the USAHEM-01-TL31 compatible with SGDM-series drives?
A: No. The USAHEM series is designed for SGDH-series drives. SGDM drives use a different encoder interface and motor parameter set. Cross-series pairing is not supported by YASKAWA and may damage the drive or motor.
Q: Can this motor be used with a third-party servo drive?
A: Technically possible with drives supporting incremental encoder input and 200 VAC 3-phase motors, but YASKAWA does not provide parameter files for third-party drives. Konmask recommends pairing with genuine SGDH drives for guaranteed performance and warranty coverage.
Q: What is the difference between TL31 and TL21 shaft suffixes?
A: TL31 denotes a straight shaft with keyway and IP67 shaft seal. TL21 denotes a straight shaft without keyway. Verify your coupling or pulley bore specification before ordering.
Q: What is the lead time for this model?
A: Stock items ship within 3–5 business days. Non-stock items typically require 4–8 weeks depending on YASKAWA production schedule. Contact us for real-time availability.
Q: Do you provide installation and commissioning support?
A: Yes. Konmask provides remote technical support including SGDH parameter configuration guides, wiring diagrams, and troubleshooting assistance at no additional charge for verified purchasers.
