ABB KUC720AE01 3BHB003431R0001/3BHB000652R0001 Main Drive Control Board 

KUC720AE01 3BHB003431R0001 is the master core control board for ABB ACS5000/ACS6000 medium voltage inverters, manufactured in Switzerland, paired with auxiliary power board 3BHB000652R0001 to form a complete drive control unit. It executes motor vector control algorithms, processes all closed-loop regulation logic, and communicates with IOEC signal board UFC719AE01 to collect field temperature, current and interlock feedback signals.

This integrated board carries multi-channel isolated DI/DO/analog terminals, internal high-speed drive bus and service debugging port. The matching 3BHB000652R0001 provides stable multi-group DC power supply for the main control circuit. It adopts rack plug-in installation with comprehensive hardware overvoltage/overcurrent protection, mine hoists and metallurgical medium voltage drive overhaul projects.
