FAQs

1. What is the 6SE7038-6GL84-1BG0 and which systems is it compatible with?

The 6SE7038-6GL84-1BG0 is an IVI (Inverter Interface) board for the Siemens SIMOVERT MASTERDRIVES series, specifically the MC and VC (Vector Control) models. It serves as the interface board between the control section and the power stage of the drive.

2. How do I know if this is the correct replacement board for my system?

Before replacement, verify the exact version on your installed board and your specific MASTERDRIVES platform (MC or VC). The IVI board is typically installed in the electronics box behind the control unit. Matching at the label level and confirming internal lay-out is essential, as compatibility depends on the installed drive version and power section type.

3. What are the typical applications for this interface board?

The 6SE7038-6GL84-1BG0 is used in demanding industrial environments requiring reliable multi-drive communication and synchronization, such as:

• Petrochemical refineries and oil & gas platforms (Zone 1 & 2 hazardous areas)

• Mining operations and mineral processing plants

• Multi-axis drive systems in heavy industry

• Legacy system maintenance and drive repair where the original IVI setup must be preserved

4. What communication protocols does the 6SE7038-6GL84-1BG0 support?

The board primarily uses the IVI (Inverter-to-Inverter) fiber-optic bus for communication between drives. For higher-level network integration, the MASTERDRIVES system (with this board installed) can be equipped with additional communication modules such as PROFIBUS DP (CBP2), DeviceNet, SIMOLINK (SLB), and Modbus, depending on the system configuration.
