ABB 3AUA0000135832 ACS880 Drive Control Interface Main Board (JCU-22 Unit Control Board) Core Function: The JCU-22 main control board is the central logic processing spare part for ABB ACS880 low-voltage industrial drives. It executes DTC (Direct Torque Control) motor algorithms, processes analog/digital I/O signals, manages communication ports, stores drive parameter firmware, and coordinates all protection circuits (overcurrent, overvoltage, overtemperature, ground fault). It receives commands from control panels, PLCs, and fieldbus adapters, then outputs PWM signals to power module IGBTs to regulate motor speed and torque for heavy industrial process loads. It supports continuous 24/7 operation for mining, water treatment, metals, pulp & paper, and HVAC systems. 2) Product Reference Web
