Compatible Replacement & Equivalent Models
When the original SGMSS-20A2A-YR11 is unavailable or discontinued, the following models offer compatible or equivalent performance. Always verify mechanical dimensions, encoder protocol, and drive compatibility before substitution.
- SGMSS-20A2A-YR12 — Same power rating, different shaft/key option; verify coupling compatibility
- SGMPH-02A1A-YR11 — Lower inertia variant (SGMPH series), 200W; suitable for lighter-load axes
- SGMGV-20A2A-YR11 — SGMGV series equivalent with higher inertia; drop-in for heavy-load applications
- Mitsubishi HG-SR202 — Cross-brand equivalent (2kW, 200V); requires drive and parameter reconfiguration
- Panasonic MHMF202L1U2M — 2kW cross-brand alternative; verify encoder wiring and connector pinout
Note: Cross-brand replacements require servo drive re-tuning and may need connector adapters. Contact Konmask for pre-sales compatibility verification.
Why Choose the Original Model
- Plug-and-play compatibility with Yaskawa YRC1000 robot controllers — no parameter re-mapping required
- 17-bit absolute encoder retains position data on power loss, reducing homing cycles

- Yaskawa factory calibration guarantees torque linearity and speed stability out of the box
- Full OEM traceability — serial number verifiable with Yaskawa service network
Typical Applications
- Yaskawa Motoman industrial robot joint drives (YRC1000 platform)
- CNC machine tool spindle and feed axis control
- Automated assembly and pick-and-place systems
- Semiconductor wafer handling equipment
- Packaging and labeling machinery
- Precision conveyor and indexing systems
System Compatibility
- Robot Controller: Yaskawa YRC1000, YRC1000micro
- Drive Unit: JZRCR-APP01-99mini, SGDV-200A01A, SGDH-20AE
- Communication Protocol: MECHATROLINK-II / MECHATROLINK-III (drive dependent)
- Power Supply: 200–240 V AC, 3-phase, 50/60 Hz
- Regenerative Option: Compatible with Yaskawa external regenerative resistor units
Selection Guide
Use the following criteria to confirm the SGMSS-20A2A-YR11 is the correct choice for your application:
- Power requirement: 2.0 kW rated output — suitable for medium-load robot joints and CNC feed axes
- Speed range: Up to 2,000 rpm continuous; confirm your motion profile does not exceed rated speed
- Inertia matching: SGMSS is medium-inertia; for high-inertia loads (>10× motor inertia), consider SGMGV series
- Encoder requirement: Absolute encoder (17-bit) — ideal for applications requiring position retention without homing
- Shaft & mounting: YR11 = straight shaft with key, flange mount — verify coupling and mounting plate dimensions
- Environment: IP67 rated — suitable for wet or dusty industrial environments
- Drive pairing: Must be paired with a compatible Sigma-series servo drive; confirm drive current rating ≥ motor rated current

Replacement & Compatibility FAQ
Q: Can I use SGMPH-02A1A-YR11 as a direct replacement for SGMSS-20A2A-YR11?
A: No. The SGMPH-02A1A-YR11 is a 200W motor vs. the 2kW SGMSS-20A2A-YR11. They are not power-equivalent. The SGMPH series is suitable for lighter auxiliary axes only.
Q: Is the SGMSS-20A2A-YR11 compatible with the JZRCR-APP01-99mini drive?
A: Yes. The JZRCR-APP01-99mini is a Yaskawa robot drive unit designed for use with the YRC1000 controller and SGMSS series motors. Verify the axis assignment and cable harness part number before installation.
Q: What is the difference between YR11 and YR12 shaft options?
A: YR11 = straight shaft with key; YR12 = straight shaft without key. Choose based on your coupling or pulley design.
Q: Can I replace a Yaskawa servo motor with a Mitsubishi or Panasonic equivalent?
A: Cross-brand replacement is technically possible but requires servo drive replacement or re-parameterization, encoder wiring adaptation, and full motion re-tuning. Contact Konmask for a compatibility assessment before proceeding.
Q: Do you supply refurbished units?
A: We supply both new OEM and certified refurbished units. Refurbished units are clearly labeled and carry a 6-month warranty. Contact us to confirm availability.
