Siemens 6SE7037-0EK84-1JC2 SIMOVERT MASTERDRIVES IGD8 Module
The IGD8 control module for documented 380–460 V AC and 510–620 V DC high-current MASTERDRIVES units.
Overview
6SE7037-0EK84-1JC2 is a Siemens SIMOVERT MASTERDRIVES spare inverter control module identified as IGD8. Siemens product data assigns it to units with 380–460 V three-phase AC, 50/60 Hz, or 510–620 V DC supply classes and 690 A or 1300 A executions.
Selection requires the host converter MLFB, current execution, board label and connector population. Similar JC-series boards are not interchangeable from appearance or family wording.

Features
Executes the IGD8 control function for the documented high-current power section.
Keeps the 690 A / 1300 A host execution attached to one exact service identity.
Uses the qualified converter connector, control and feedback arrangement.
Supports legacy service when parameters, software and board records are preserved.
Applications
- Verified 690 A or 1300 A SIMOVERT MASTERDRIVES converter service.
- High-power drive maintenance with complete host and connector evidence.
- Obsolescence planning for installed MASTERDRIVES power sections.
Lifecycle
- Back up parameters, software identity, options and fault history.
- Record the host MLFB, rating plate, current execution and every connector.
- Apply lockout, observe DC-link discharge time and verify absence of voltage.
- Inspect cooling, gate circuits and power components before staged commissioning.
FAQ
Which host information must accompany an enquiry for 6SE7037-0EK84-1JC2?
Provide the converter MLFB, rating plate, 690 A or 1300 A execution, board labels, connector photos and fault history.
Can another IGD8 board replace 6SE7037-0EK84-1JC2 because it looks the same?
No. Host voltage, current class, suffix, connector population and the Siemens service record must agree.
What should be preserved before removing 6SE7037-0EK84-1JC2?
Save parameters, software or memory identity, option configuration and diagnostic history.
Why inspect the power section before fitting 6SE7037-0EK84-1JC2?
A cooling, gate-drive, DC-link or semiconductor fault can damage the replacement.
How should replacement 6SE7037-0EK84-1JC2 be released?
Complete controlled energization, diagnostics, protection checks and a documented motor test.
