1. What is the 6SE7031-5EF84-1JC1 and what does it do?
The 6SE7031-5EF84-1JC1 is an IGD1 Inverter Gate Driver module for the Siemens SIMOVERT MASTERDRIVES series. It converts low-voltage PWM signals from the control board into high-current gate drive pulses to switch the IGBTs in the inverter section. It also provides critical protection functions including desaturation detection (short-circuit protection), overcurrent monitoring, and fault feedback to the control board .
2. What faults are associated with IGD board failure?
IGD board failures typically manifest as F025, F026, or F027 fault codes on the drive display:
F025 = UCE shutdown in Phase L1
F026 = UCE shutdown in Phase L2
F027 = UCE shutdown in Phase L3
Replacing the IGD board for the corresponding phase is the standard remedy . However, before replacing the board, check all fiber-optic connections from the IVI board to the IGD board first .
3. Is this product still in production?
No. This product reached End-of-Life status on September 30, 2020 (PLM PM490) . It is no longer available from Siemens directly but remains available as a spare part from specialized industrial suppliers offering "New Factory Sealed" (NFS) or reconditioned units. The product has a migration path to the SINAMICS series.
4. What are the key specifications of this module?
The module operates on 380-460V AC (3-phase, 50/60 Hz) or 510-620V DC input, with a rated current of 92A and peak current capacity of 146A . It supports vector control and V/f control modes, operates at 0-100 Hz frequency range, and offers >95% efficiency .
5. What should I check before replacing the IGD1 board?
Before replacing the IGD1 module, Siemens support recommends:
Check all fiber-optic connections from the IVI board to the IGD board
Inspect the board for visible damage (burnt components, swollen capacitors)
Verify the exact part number and version of your installed board matches the replacement
Ensure the correct input voltage (380-460V AC) and current rating (92A/146A) for your system
