Siemens 6SE7034-5HK84-1JC0 – IGBT Gate Drive Trigger Board | SIMOVERT MASTERDRIVES MC/VC
The Siemens 6SE7034-5HK84-1JC0 is the OEM IGBT Gate Drive (IGD) trigger board engineered for the SIMOVERT MASTERDRIVES MC and VC series high-power inverter drives. Designed for demanding industrial environments where drive uptime is mission-critical, this board governs the precise gate-pulse sequencing of the IGBT power stack — directly controlling motor torque, speed accuracy, and fault-response behavior.
At Konmask.com, we source this component through verified industrial channels, perform incoming inspection against Siemens OEM specifications, and ship with full traceability documentation — giving procurement engineers a reliable, low-risk replacement path for aging MASTERDRIVES installations.

Proven Application Environments
- Heavy Industry: Steel rolling mills, paper machines, cement kilns — high-inertia loads requiring precise torque control
- Marine & Offshore: Thruster drives, winch systems, and pump drives in MASTERDRIVES VC configurations
- Mining: Conveyor belt drives, hoist systems, and crusher motor control
- Oil & Gas: Compressor and pump motor drives in hazardous-area-adjacent panels
- Power Generation: Auxiliary drive systems in power plant balance-of-plant applications
- Water Treatment: Large pump station VFD systems requiring long MTBF components
Engineering Advantages
- OEM Gate-Pulse Fidelity: Maintains Siemens-specified rise/fall times and dead-band timing — critical for preventing IGBT shoot-through in high-power stacks
- Fault Isolation Architecture: Onboard desaturation detection and short-circuit protection signals propagate to the CU board within microseconds
- Direct Drop-In Replacement: Identical PCB footprint, connector pinout, and firmware compatibility with the original 6SE7034-5HK84 drive chassis
- Reduced Commissioning Time: No parameter re-entry required — drive recognizes board via hardware ID on power-up
- Long Service Life: Industrial-grade components rated for continuous duty in high-vibration, high-temperature drive cabinets
System Architecture & Signal Flow
In the MASTERDRIVES power chain, the 6SE7034-5HK84-1JC0 IGD board sits between the control unit (CU) and the IGBT power module:
- CU / SCB Control Unit → generates PWM gate-pulse commands via fiber-optic or ribbon interface
- IGD Trigger Board (6SE7034-5HK84-1JC0) → amplifies, isolates, and distributes gate signals to each IGBT in the 3-phase bridge; monitors desaturation and overcurrent; returns fault status to CU
- IGBT Power Module → switches DC bus voltage to produce variable-frequency AC output to motor
- Motor → receives controlled torque/speed command
A failed or degraded IGD board typically manifests as: F002/F005 overcurrent faults, asymmetric phase output, erratic torque response, or drive trips on power-up without load.

Technical FAQ
Q: Can this board be used in both MASTERDRIVES MC and VC variants?
A: Yes. The 1JC0 IGD board is common to both Motion Control (MC) and Vector Control (VC) variants of the 6SE7034-5HK84 chassis. Confirm the drive’s CU board type before ordering if unsure.
Q: What faults indicate a failed IGD board?
A: Common symptoms include F002 (overcurrent), F005 (I²t overload), asymmetric output voltage on one phase, or the drive tripping immediately at enable with no load connected. Always rule out IGBT module failure first using a gate-drive tester.
Q: Do you provide a test report with the board?
A: Yes. Every unit ships with a functional test report confirming gate-signal output levels and fault-signal response were verified on a reference drive.
Q: What is the lead time?
A: In-stock units ship within 1–2 business days. If sourcing is required, typical lead time is 7–15 business days. Contact us for real-time stock status.
Q: Can I return the board if it does not resolve my fault?
A: Yes, within 30 days of receipt, provided the board is returned in original condition with the test report. Contact support@konmask.com to initiate an RMA.
