Description
The ABB BCU‑02 (3AUA0000110429) is a dedicated brake control unit designed for ABB ACS series variable frequency drives. It handles the timing logic for motor mechanical brake opening and closing. The unit receives control commands from the drive, outputs relay signals to trigger the motor brake, and feeds back brake status signals to the drive controller. It prevents motor slipping during start‑up and stop‑down for hoisting, lifting and vertical‑motion applications. Widely used as spare‑part replacement for legacy ABB drive systems in crane and material‑handling equipment.
Series
ABB Drive Brake Control Unit Series. The BCU‑02 works with ABB ACS800 / ACS850 and compatible drive units for lifting‑application brake management. It solves the coordination problem between frequency converter torque output and mechanical brake action.
Product Features
- Accurate sequence control for mechanical brake release and closing for lifting‑type motor loads
- Relay output for driving external motor brake coil
- Digital signal interface for status feedback between BCU‑02 and ABB drive
- 24 VDC auxiliary power supply input, short‑circuit protection function
- DIN‑rail mounting design, easy cabinet installation and wiring
- Front‑panel LED indicators for power, running state and fault diagnosis
- Optimized for hoist, crane and vertical lifting working conditions, avoids load drop risk
- Compact modular structure, convenient for field‑site spare‑part replacement
