Compatible Replacement & Equivalent Models
When the SGMRV-05ANA-YR21 is unavailable or discontinued, the following models may serve as functional replacements. Always verify electrical and mechanical compatibility before substitution.
- Yaskawa SGMRV-05ANA-YR11 – Same power class, different encoder/option suffix; verify encoder compatibility with your drive
- Yaskawa SGMRV-05ANA-YR31 – Alternative option code; confirm brake/connector configuration
- Yaskawa SGMGV-05ADA – Standard (non-hollow) 400W servo motor; suitable if hollow shaft is not required
- Mitsubishi HG-KR43 – 400W class AC servo motor; requires drive and cable adaptation
- Panasonic MHMF042L1U2M – 400W AC servo motor; different connector and drive protocol
Note: Cross-brand replacements require drive parameter reconfiguration and mechanical adapter verification. Contact Konmask for sourcing support.
Why Choose the Original Model
- Hollow-shaft design enables cable or shaft pass-through, reducing system complexity in rotary table and joint applications
- Direct-drive architecture eliminates gearbox backlash, delivering superior positioning repeatability
- 17-bit absolute encoder retains position data on power loss, reducing homing cycles and downtime
- Yaskawa Σ-series ecosystem ensures seamless integration with SGDV/SGDH drives and SigmaWin+ tuning software
- IP67 protection suits demanding environments including coolant splash and dust exposure
Typical Applications
- Rotary indexing tables and turntables in CNC machining centers
- Robotic joint actuators (SCARA, articulated arm)
- Semiconductor wafer handling and inspection equipment
- Medical imaging and surgical robot axes
- Precision assembly and pick-and-place systems
- Laser cutting and engraving rotary axes
System Compatibility
- Servo Drives: Yaskawa SGDV-2R8A01A, SGDV-5R5A01A, SGDH series; Σ-7 SGDV7S series
- Controllers: Yaskawa MP3300, MP2600iec; Siemens S7-1500 (via EtherCAT gateway); Mitsubishi iQ-R (via MECHATROLINK adapter)
- Communication Protocols: MECHATROLINK-II / III (native); EtherCAT, PROFINET (via gateway)
- Software: Yaskawa SigmaWin+, DriveWizard Industrial
Selection Guide
Use the following criteria to confirm the SGMRV-05ANA-YR21 is the correct model for your application:
- Power requirement: 400 W rated output — suitable for light to medium load rotary axes
- Hollow shaft needed? If yes, SGMRV series is correct; if no, consider SGMGV or SGMJV for cost savings
- Encoder type: Absolute encoder required for applications without homing on startup
- Drive on hand: Confirm existing drive is SGDV or Σ-7 compatible; check current rating matches motor
- Option suffix -YR21: Verify connector type, brake option, and shaft seal match your mechanical design
- Environment: IP67 rated — suitable for wet/dusty environments; confirm cable entry sealing

Replacement & Compatibility FAQ
Q: Can I replace SGMRV-05ANA-YR21 with a standard (non-hollow) Yaskawa servo motor?
A: Yes, if your mechanical design does not require cable pass-through. The SGMGV-05ADA offers similar power in a standard flange format, but requires a different mounting adapter.
Q: Is the SGMRV-05ANA-YR21 compatible with Σ-7 drives?
A: The SGMRV series was designed for Σ-V (SGDV) drives. Σ-7 compatibility depends on firmware version and drive model — consult Yaskawa’s compatibility matrix or contact Konmask for verification.
Q: What does the suffix -YR21 mean?
A: Yaskawa option suffixes encode connector type, brake presence, shaft seal, and other mechanical options. -YR21 specifies a particular connector and configuration — always match this suffix when ordering a direct replacement.
Q: Do you offer warranty on this product?
A: Yes. Konmask provides a standard 12-month warranty on new units and 90-day warranty on tested surplus units. Terms are confirmed at time of quotation.
Q: Can you source discontinued or hard-to-find SGMRV models?
A: Yes — sourcing legacy and discontinued Yaskawa servo motors is a core competency at Konmask. Contact us with your model number and quantity.
