IV. Working Principle and Application Logic
The ABB BCU-02 3AUA0000110429 control unit achieves precise control of heavy industrial equipment relying on ACS880 variable frequency drives based on the closed-loop working logic of "signal acquisition - logic computing - fiber optic transmission - control execution". Its core working process is as follows:
The unit accesses external control signals (such as equipment start-stop commands, speed regulation signals, safety interlock signals, etc.) through its built-in digital input interface. Meanwhile, it receives real-time operating status data fed back by the ACS880 variable frequency drive via a dedicated interface, establishing a bidirectional data interaction link.
Relying on the built-in high-performance microprocessor, it performs fast logic computing on the collected external control signals. Combined with preset control parameters (such as speed thresholds, start-stop sequences, safety interlock rules, etc.), it generates precise control commands. At the same time, it parses the operating data fed back by the drive to determine whether the equipment operating status is normal.
The generated control commands are stably transmitted to the ACS880 variable frequency drive via fiber optic links, driving the actuator to complete operations such as equipment start-stop, speed regulation, and position control. Meanwhile, the equipment operating status data is transmitted back to the control unit in real time via fiber optic links, achieving synchronous interaction between control commands and operating status.
