Application-Specific FAQ
Q: Is the SRDA-SDA71A01A-1 compatible with MECHATROLINK-III controllers?
A: No. This amplifier uses MECHATROLINK-II protocol. MECHATROLINK-III requires the Sigma-V or Sigma-7 series amplifiers.
Q: Can this drive operate with third-party servo motors?
A: The SRDA-SDA71A01A-1 is optimized for Yaskawa Σ-III series motors. Third-party motor use requires careful encoder and parameter matching and is not recommended without engineering validation.
Q: What is the difference between SRDA-SDA71A01A-1 and SRDA-SDA71A01A?
A: The “-1” suffix typically denotes a hardware revision. Verify compatibility with your system’s firmware version before substitution.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all tested units. Extended warranty available on request.
Q: Can I get a test report or inspection certificate?
A: Yes, traceable inspection documentation is available upon request for OEM and MRO procurement teams.
