Allen-Bradley 320087-A06 – Drive Board | PowerFlex Series Platform
Engineering Background
The Allen-Bradley 320087-A06 is a factory-original drive control board engineered for Rockwell Automation’s PowerFlex variable frequency drive (VFD) platform. Designed to operate within demanding industrial environments, this board serves as the core signal processing and gate-drive interface layer between the control logic and power switching stages of the drive system.
Product Positioning
Targeted at maintenance engineers, OEM integrators, and MRO procurement teams requiring a verified, drop-in replacement or spare board for PowerFlex drive systems. The 320087-A06 eliminates the need for full drive replacement, reducing downtime cost and capital expenditure in production-critical applications.

Engineering Advantages
- OEM-Identical Replacement: Direct plug-in compatibility — no firmware re-flashing or parameter re-mapping required in most configurations
- Reduced Downtime Risk: Stocking this board as a critical spare eliminates multi-week lead times for new drive procurement
- Cost Efficiency: Board-level repair is typically 60–80% less expensive than full drive replacement
- Traceability: Each unit supplied with original part number label and revision marking for maintenance records
- Pre-shipment Testing: Functional verification performed on all refurbished units prior to dispatch
System Architecture & Signal Flow
The 320087-A06 board interfaces between the drive’s main control board (logic layer) and the IGBT power module (switching layer). Its primary functions include:
- Gate Drive Signal Conditioning: Amplifies and isolates PWM signals from the DSP control board to IGBT gate inputs
- Fault Detection & Protection: Monitors over-current, over-temperature, and desaturation events; triggers hardware fault latch to protect power stage
- Isolated Feedback Path: Returns DC bus voltage and current feedback signals to the control board via optocoupler isolation
- Power Supply Distribution: Distributes regulated auxiliary voltages (+15V / -15V / +5V) to gate drive circuits and onboard logic
Signal flow: Control Board DSP → PWM Output → 320087-A06 Gate Drive Amplifier → IGBT Module → Motor Output
Sourcing & Quality Verification
- Source Traceability: Units sourced from authorized distributors, OEM factory surplus, or decommissioned equipment with documented service history
- Inspection Protocol: Visual inspection (PCB, connectors, solder joints), component-level verification, and functional power-up test
- Counterfeit Mitigation: Part number, date code, and revision marking cross-referenced against Rockwell Automation published documentation
- Packaging: Anti-static bag + foam insert + outer carton; humidity indicator card included for long-distance shipments
- Warranty: 12-month warranty on tested/refurbished units; 90-day warranty on factory surplus (as-removed) units

Technical FAQ
Q: Is the 320087-A06 compatible with all PowerFlex drive frame sizes?
A: Compatibility depends on the specific PowerFlex model and frame size. Please provide your drive catalog number when requesting a quote so we can confirm fitment.
Q: Can this board be used with a different revision drive (e.g., A04 or A05)?
A: Revision changes may affect connector pinout or firmware compatibility. We recommend using the exact revision specified on your existing board label. Contact our technical team for cross-revision guidance.
Q: Do you provide a test report with the unit?
A: Yes. All refurbished units ship with a functional test report documenting power-up verification and fault-free operation.
Q: What is the typical lead time for stock items?
A: In-stock units ship within 1–2 business days of order confirmation. Out-of-stock items are sourced within 5–15 business days depending on availability.
Q: Can you supply multiple units for a spare parts program?
A: Yes. We support blanket orders and consignment stocking programs for facilities with ongoing MRO requirements. Contact us for volume pricing.
