ASE2UDC920AE01

Function
Multi protocol signal conversion communication
Equipped with Modbus RTU, DeviceNet, and DP bus protocol processing chips, it interfaces with the frequency converter DCU main control board while forwarding analog, fault, and speed data to the upper DCS (AC800F/800xA, AO801/AO845A-eA).
Local DI/DO digital quantity acquisition and output
Integrate multiple digital input and output channels, collect fans, temperature control, threshold positions, and emergency stop switches inside the cabinet; Output fault alarm, fan start stop, and brake circuit control signals.
PID closed-loop auxiliary regulation
Independent PID operation can directly complete speed, bus voltage, and temperature assisted closed-loop control, reducing the computational load on the DCU motherboard.
Centralized diagnosis of complete machine faults
Summarize all fault codes for IGBT driver faults (APBU-44C), power module (ARCOLO0339), and analog acquisition board (ARC093AV1), and upload them to the upper level uniformly; The panel LED indicator lights indicate the fault location in segments.
Signal electrical isolation
Internal communication, I/O channels, and high-voltage power circuits are isolated to resist high-frequency interference from IGBT in the frequency conversion cabinet, avoiding signal drift and communication interruption.
