Selection Guide
Use the following checklist to confirm the correct triggering module for your drive:
- Identify the drive frame size from the nameplate (Frame D / E / F / G).
- Note the rated output current (e.g., 31.7 A for 6SE7031-x).
- Confirm the IGBT module type installed in the power stack.
- Check the fiber-optic connector type (HFBR vs. direct PCB).
- Verify firmware revision compatibility with your CU board.
- If unsure, send your drive nameplate photo to support@konmask.com for a free selection check.

Replacement & Compatibility FAQ
Q: Can I use 6SE7031-5EF84-1JC1 as a direct replacement?
A: Only if the current rating and IGBT stack match. Contact us for a verified cross-reference before ordering.
Q: Is this module compatible with SINAMICS drives?
A: No. The 6SE7031-7HG84-1JC1 is specific to the MASTERDRIVES platform. SINAMICS uses a different gate-drive architecture.
Q: Do you supply refurbished units?
A: Yes. Refurbished units are fully tested and carry a 6-month warranty. Specify “refurbished” in your inquiry for pricing.
Q: Can you provide a datasheet?
A: Yes. Request the SIEMENS MASTERDRIVES hardware installation manual and module datasheet via email.
Q: What is the lead time for out-of-stock units?
A: Typically 5–15 business days depending on sourcing channel. Rush sourcing available — contact us.
