ABB UFC760BE42 (3BHE004573R1042) Control Board for ACS/Industrial Drives – Core Drive Control & I/O Interface
The ABB UFC760BE42 – part number 3BHE004573R1042 – is a drive control board used in ABB industrial drive systems, typically within the ACS600/ACS800 family. From my experience, this module handles the real-time coordination between the drive’s control logic and power section, supporting feedback, internal I/O, and—on certain variants—fiber optic links to the power unit. It’s a common replacement when a drive shows intermittent faults, comms drops to the power stage, or unstable speed/torque control after a power event.
Our Order Process & Guarantees
- Quotation & confirmation: We confirm availability and firmware/variant compatibility before you place the order.
- Lead time: In stock items ship in about 1 week; not in stock typically within 2–4 weeks, no more than 1 month at the latest.
- Payment: 50% advance payment; full payment prior to delivery.
- Shipping: Express via FedEx, UPS, or DHL.
- Warranty: 365 days. Units are function-tested before dispatch.
Key Features
- Drive control core: Coordinates speed/torque commands, protection logic, and real-time feedback with the power unit.
- Backplane integration: Plugs directly into the host drive’s control rack, minimizing wiring and setup time.
- Fiber optic channels (variant-dependent): You might notice optical ports used to interface the power stage or gate units for noise-immune communication.
- Robust against electrical noise: Designed for harsh industrial cabinets where EMI can be a challenge.
- Service-friendly: Supports quick swap with standard ESD handling; typically no field rework required beyond parameter verification.
- Firmware compatibility: Works with the drive’s existing firmware family; we can help check the exact BE42/R1042 match.
Recommended Supporting Components
- Drive fiber optic link cables: For boards using optical communication to the power unit; replacing aged fibers often stabilizes intermittent faults.
- Backplane connector kit: Fresh connectors reduce contact resistance after years of thermal cycling.
- Grounding/ESD service kit: Helpful for safe board swap in cabinets with limited space.

Application Fields
This control board is typically used in heavy-duty and continuous process environments: steel and metals rolling, paper machines, pumps and compressors, cranes/hoists, marine propulsion auxiliaries, and large HVAC drives. One thing I appreciate is how it restores legacy drive systems with minimal re-engineering—useful when downtime penalties are high and a full drive retrofit isn’t on the table yet.
Advantages & Value
- Reliability: OEM-grade board designed for EMI-heavy cabinets; reduces nuisance trips in many cases.
- Compatibility: Matched to ABB drive firmware families; we help verify BE42/R1042 against your drive type code.
- Cost control: Direct swap minimizes engineering time and avoids a full drive upgrade.
- Technical support: Assistance with parameter backups, basic commissioning checks, and handling practices.
Installation & Maintenance
- Cabinet environment: Install in a clean, ventilated enclosure meeting the drive’s IP and cooling specs; avoid conductive dust.
- Power down & ESD: Fully isolate the drive, wait for DC link discharge, and use an ESD wrist strap; handle by edges only.
- Wiring & seating: Inspect backplane connectors, reseat firmly, and secure with standoffs/screws to prevent vibration‑related intermittence.
- Parameter/firmware checks: Back up parameters before the swap; after replacement, verify firmware family and key control settings.
- Routine care: Annual cabinet cleaning and connector inspection; update firmware during planned outages when recommended by ABB.
Quality & Certifications
- Compliance: Meets ABB’s industrial drive component standards; CE/EMC conformity is ensured at the drive assembly level; RoHS-compliant in most cases.
- Safety/Agency: Typically used within UL/CE certified drive systems.
- Warranty: 365 days standard warranty coverage.
Quick customer note: a maintenance team in a rolling mill swapped this exact board after sporadic overcurrent trips tied to fiber link errors. After replacing the UFC760BE42 and the two short optical jumpers, the drive ran stable for months—no parameter changes needed beyond a basic sanity check. That seems to be the usual pattern when the fault history points to the control/power interface.
