Provides the control-interface board execution documented for the 260 A MICROMASTER 430 FX drive.
Technical Summary
6SL3351-6FE32-6AA1 is a Siemens replacement control interface board for a MICROMASTER 430 drive. Siemens identifies this execution with a 3AC 380–480 V, 50/60 Hz, 260 A host rating and FX frame size.
The FE code, 260 A rating and MICROMASTER 430 platform distinguish 6SL3351-6FE32-6AA1 from nearby FE and GE boards. Select it from the complete board and host-drive labels, not from appearance.

Features
Keeps the FE32-6 identity separate from the 210 A FE32-1 and 380 A FE33-8 variants.
Supports board-level maintenance when the host drive and all connectors are documented.
Fits a legacy drive service workflow that includes parameter backup and controlled recommissioning.
Compatibility
- Verify MICROMASTER 430, 260 A and FX on the host rating plate before ordering.
- Match the complete 6SL3351-6FE32-6AA1 MLFB on the removed board.
- Record every plug, ribbon cable, option and grounding point with orientation photographs.
- Check the Siemens spare-part and lifecycle documentation for an approved supersession if the exact board is unavailable.
Replacement
- Back up drive parameters and record active option settings before isolation.
- Apply lockout, wait the specified DC-link discharge time and verify absence of voltage.
- Use ESD controls and transfer connectors one at a time from the documented board map.
- Inspect cooling, contamination and connector seating before restoring covers.
- Perform controlled power-up, verify diagnostics and prove motor rotation, feedback and interlocks.
FAQ
Can 6SL3351-6GE32-6AA1 replace 6SL3351-6FE32-6AA1?
No automatic equivalence should be assumed: the GE board is listed for MICROMASTER 440, while this FE board is listed for MICROMASTER 430.
Why is the host rating plate required for 6SL3351-6FE32-6AA1?
It confirms the MICROMASTER family, 260 A execution and FX frame that Siemens associates with this board.
What should be backed up before replacing 6SL3351-6FE32-6AA1?
Save parameters, option configuration, motor data, I/O assignments, fault history and any application-specific commissioning record.
What condition checks matter before fitting 6SL3351-6FE32-6AA1?
Inspect fans, heatsinks, DC-link area, power connections, ribbon cables and evidence of contamination or overheating.
How should a repaired drive using 6SL3351-6FE32-6AA1 return to service?
Use a controlled start with current, direction, feedback, interlocks and application response monitored against the commissioning record.
