Application-Specific FAQ
Q: Is 3HAC040657-002 backward compatible with 3HAC040657-001?
A: Yes. Both revisions are functionally interchangeable within the IRC5 MU300 slot. Confirm firmware version compatibility with your ABB service engineer for safety-critical applications.
Q: Can the MU300 be used with IRC5 Compact controllers?
A: The MU300 is primarily designed for the IRC5 standard cabinet. For IRC5 Compact, verify the drive slot dimensions and power rating before installation.
Q: What is the difference between MU300 and MU100 (3HAC040655-002)?
A: The MU100 (DSQC532B) is the IO expansion module, while the MU300 is the motor drive unit. They are often replaced together as a matched set during IRC5 drive section overhauls.
Q: Do you provide an ABB certificate of conformity?
A: We provide available OEM documentation. For new units, ABB CoC is included. For refurbished units, our internal inspection report is provided. Contact us for specifics.
Q: What is the lead time for bulk orders (10+ units)?
A: Bulk sourcing lead times are typically 5–15 business days depending on stock. Contact us early for production line shutdown planning.
