Get to the hardware inside the drive.
VFD Boards, Power Electronics and Support Hardware
Control boards, power electronics, interfaces, and support components. Start with the full board number and the drive it belongs to.
Boards & control electronics
Identify both the board and its parent drive. A drive series alone does not define the electronic assembly.
Main control & processor boards
Complete board number, hardware revision, firmware context, and parent drive model.
Discuss control hardwareInterfaceI/O, communications & operator panels
I/O modules, communication options, keypads, and operator-interface hardware.
Send the module numberUNITROL P excitationABB HIEE300766R0001
GD B021 BE01 gate control unit. Send the installed label and revision.

The installed drive and power section provide the identification context.
Gate drivers & power boards
Gate-driver assemblies, rectifier and inverter boards, and associated control hardware.
Send the assembly numberSemiconductorsPower modules & assemblies
IGBT and other power assemblies identified by their own markings and installed configuration.
Discuss the power sectionElectrical ratings, revision, firmware, connectors, and application all matter. A board with the same shape or a related number is not automatically a replacement.
Cooling, braking & support
Keep the drive support components in the same technical context as the drive itself.
Cooling assemblies
Fans, blowers, and cooling components. Include voltage, connector, and mounting information.
DC-link & braking hardware
Capacitor assemblies, braking components, and resistor packages. Include the drive and assembly ratings.
Start from the parent drive.
Use the complete-drive families to identify the equipment behind a board or accessory request.
ABB ACS
AC drive families and the identification details to include.
Explore this categoryDrive familyAllen-Bradley PowerFlex
750-series drives and complete catalog-number context.
Explore this categoryGenerator excitation is a separate equipment family. An excitation-system control board should be identified from its own system and part number, rather than treated as a VFD board.
Send both labels.
Include the drive nameplate, board or assembly number, revision, quantity, and clear photographs. Add firmware details and the application where relevant.
Independent supplier, not an authorized distributor. Manufacturer names and part numbers are used for identification. Exact configuration is checked for each request, and condition is disclosed before sale.
