Siemens 6SE7038-6EK84-1GG0 – High-Power Output Module | MASTERDRIVES MC/VC Platform
Engineering Background
The Siemens 6SE7038-6EK84-1GG0 is a high-power output (inverter) module designed for the SIMOVERT MASTERDRIVES MC/VC series — Siemens’ flagship modular AC drive platform for demanding industrial motion control and process automation applications. This unit forms the core power conversion stage of a cabinet-mounted drive system, converting DC bus voltage into precisely controlled three-phase AC output to drive induction and synchronous motors.
Product Positioning
Engineered for heavy-duty continuous operation in steel mills, paper machines, mining conveyors, marine propulsion, and large HVAC systems, the 6SE7038-6EK84-1GG0 delivers reliable high-current output with full compatibility with Siemens MASTERDRIVES control boards (CU, CB, TB). It is the preferred choice for procurement engineers requiring a drop-in replacement or system expansion module with guaranteed OEM interoperability.

System Architecture & Signal Flow
In a MASTERDRIVES MC/VC system, the 6SE7038-6EK84-1GG0 sits between the rectifier/DC bus section and the motor terminals:
- DC Bus Input → Receives stabilized DC voltage from the rectifier module (6SE703x-xExx-xAx0)
- IGBT Inverter Stage → PWM switching converts DC to variable-frequency, variable-voltage 3-phase AC
- Gate Drive Interface → Receives firing pulses from the Control Unit (CU) via the internal fiber-optic or direct interface
- Motor Output Terminals → U2/V2/W2 terminals connect directly to motor cable (screened cable recommended)
- Feedback & Protection → Current sensors feed back to CU for closed-loop vector control (VC mode) or V/f control (MC mode)

Technical FAQ
Q: Is the 6SE7038-6EK84-1GG0 compatible with both MC and VC control units?
A: Yes. The output module is hardware-compatible with both Motion Control (MC) and Vector Control (VC) variants of the MASTERDRIVES platform. The control mode is determined by the CU board, not the output module.
Q: Can this module be used as a standalone inverter?
A: No. It requires a separate rectifier/DC bus supply and a MASTERDRIVES control unit (CU) to operate. It is a power section module only.
Q: What is the motor power rating this module supports?
A: Based on the 6SE7038-6EK84 frame designation, this module is rated for approximately 200–250 kW motor drives at 400 V AC supply. Confirm exact kW rating with your Siemens drive configurator or contact us.
Q: Are spare IGBT modules available separately?
A: We can source compatible IGBT sub-modules. Please contact us with your specific requirement.
Q: Do you provide installation and commissioning support?
A: Remote technical guidance is available. On-site commissioning can be arranged through our partner network in major industrial regions.
