Provides the control-interface execution documented for the 260 A MICROMASTER 440 FX drive.
Product Identification
6SL3351-6GE32-6AA1 is the Siemens replacement control interface board listed for a MICROMASTER 440 drive with 3AC 380–480 V, 50/60 Hz supply class, 260 A rating and FX frame size.
The GE prefix identifies the MICROMASTER 440 application. It must not be replaced on the assumption that the same-current FE32-6 board for MICROMASTER 430 is equivalent.

Functions
Maintains the GE-coded board identity required for the MICROMASTER 440 platform.
Interfaces with documented internal connectors and drive options during board-level service.
Supports controlled restoration when the original parameters and host record are available.
Applications
- Legacy MICROMASTER 440 FX drives whose rating plate confirms the 260 A execution.
- Board-level repair where the installed label is exactly 6SL3351-6GE32-6AA1.
- Planned spare holdings tied to a verified drive asset and parameter archive.
- Controlled drive recommissioning after diagnostics identify the interface board as the service scope.
Lifecycle
- Record the host-drive MLFB, serial number, firmware and option set before procurement.
- Keep a validated parameter backup and connector map with the spare.
- Use Siemens documentation to confirm any supersession or migration route.
- Investigate cooling, contamination and upstream faults so a replacement board is not exposed to the same cause.
- Prove motor, feedback, I/O and safety interfaces during controlled return to service.

FAQ
Can 6SL3351-6FE32-6AA1 replace 6SL3351-6GE32-6AA1?
No direct interchange should be assumed: FE32-6 is listed for MICROMASTER 430, while this GE32-6 board is listed for MICROMASTER 440.
Which host details should accompany an enquiry for 6SL3351-6GE32-6AA1?
Send the drive MLFB, serial number, 260 A rating, FX frame confirmation, board label and clear connector photographs.
What information should be retained with a spare 6SL3351-6GE32-6AA1?
Keep its intended asset, parameter backup, firmware and option record, connector map and commissioning baseline.
Why should the failed drive be inspected before fitting 6SL3351-6GE32-6AA1?
Fan failure, contamination, loose power joints or DC-link faults can damage the replacement if the root cause remains.
What is the minimum return-to-service test for 6SL3351-6GE32-6AA1?
Verify clean diagnostics, correct motor direction and current, feedback, I/O, interlocks and application response during a controlled run.
