Siemens 6SE7038-6GL84-1BG0 IVI Interface Board
The 6SE7038-6GL84-1BG0 is an IVI interface board for SIMOVERT MASTERDRIVES inverter systems. Siemens lists this exact part as an IVI module, and the MASTERDRIVES service literature explains that IVI means Inverter-Value Interface, described there as the interface board for the power section.
That puts this board in the inverter power-section interface layer rather than in the operator panel or field I/O section.
This matters in real maintenance work because a board in the IVI position is tied to the internal inverter section and its signal path to the power stage.
The same Siemens service documentation shows IVI replacement procedures inside the electronics box and identifies 6SE7038-6GL84-1BG0 as an IVI inverter interface board used with specific MASTERDRIVES power sections.

Application Scenarios
This board is suited to SIMOVERT MASTERDRIVES inverter repair, especially where the installed drive still uses the original IVI layout and the internal power-section interface must remain unchanged.
It is most relevant in board-level restoration of legacy MASTERDRIVES units, where the drive hardware remains in service and only the IVI section requires replacement.
Product Replacement Guide
Before replacing 6SE7038-6GL84-1BG0, confirm the exact order number on the installed board, the MASTERDRIVES platform, and the installed power-section type. Siemens’ replacement instructions for IVI boards show that the board is mounted inside the electronics box and connected through multiple plugs and, on some types, fiber-optic connections and nearby PSU components.
That makes label-level matching and internal layout confirmation more important than external appearance alone.
FAQ
Q1. What type of board is 6SE7038-6GL84-1BG0?
It is an IVI interface board for SIMOVERT MASTERDRIVES. Siemens identifies it as an IVI module, and MASTERDRIVES service literature defines IVI as the Inverter-Value Interface, the interface board for the power section.
Q2. What does this board do in the system?
Its role is to connect the inverter control side to the power section.
Siemens’ service text places the IVI board directly in the inverter electronics box and describes it as the power-section interface board.
Q3. What should be checked when selecting 6SE7038-6GL84-1BG0?
Check the full Siemens order number, confirm the drive is part of the SIMOVERT MASTERDRIVES family, and verify that the installed unit uses this exact IVI board position in the electronics box.
Siemens also ties this board to specific power sections in the service tables.
Q4. How should the key specification be understood?
The critical identifier is IVI, not just “interface board.” In Siemens terminology, IVI means the interface board for the power section, so the matching point is the inverter section and internal hardware architecture, not only the connector layout.
Q5. How should faults be diagnosed before replacing this board?
Start by separating an IVI / power-section interface fault from a main control fault or a power-device fault.
If the drive family and installed hardware match this IVI position and the issue traces back to the interface path inside the electronics box, the IVI board becomes a stronger replacement candidate.
