Siemens 6SL3351-6FE35-0AA1 Control Interface Board
A replacement control interface board for the 250 kW, 380–480 V MICROMASTER 430 GX drive execution.
Overview
6SL3351-6FE35-0AA1 is a Siemens replacement Control Interface Board for the MICROMASTER 430 GX power class. Siemens service documentation assigns it to the 6SE6430-2UD42-5GA0 drive execution.
The board is a drive-specific service component rather than a stand-alone controller. Its exact article number, connector pattern and host-drive identity must be retained during maintenance.

FAQ
Why is the complete host-drive code required for 6SL3351-6FE35-0AA1?
The control interface board is assigned to a specific MICROMASTER 430 power execution; frame and current-class differences can prevent a safe fit.
What should be preserved before replacing 6SL3351-6FE35-0AA1?
Retain the parameter archive, drive nameplate, connector photographs, option-board list, I/O schedule and active fault record.
Can 6SL3351-6FE35-0AA1 repair a drive with a power-stage fault?
Not by itself. Confirm the fault location and test the power section, gate drive, auxiliary supplies and connected motor before changing the interface board.
What ESD controls apply when handling 6SL3351-6FE35-0AA1?
Use a grounded workstation and approved handling methods, and keep the board in antistatic packaging until the converter is safely isolated and ready.
How should a drive be accepted after installing 6SL3351-6FE35-0AA1?
Restore the approved parameter set, check diagnostics and I/O, verify motor identification, then complete a low-risk functional test before production load.
