Main Functions

1. Strip position & width signal acquisition and processing Receive analog signals from edge sensors (photoelectric, ultrasonic sensors). Calculate real‑time strip edge offset, centre deviation and actual strip width with high‑speed internal DSP processing. Provide configurable hardware filtering (1 ms‑2000 ms) to suppress industrial noise interference.
2. Closed‑loop EPC / WPC control (Edge Position Control / Width Position Control) Built‑in PID control algorithm. Output analog control signals to drive servo actuators for web guiding systems. Real‑time dynamic correction for strip wandering, keeps strip centred on the production line, prevents strip deviation, wrinkling and edge damage.
3. Rich I/O interface processing

ABB Millmate Controller 400R (PFXA401S, 3BSE024388R2)

• 4 channels differential analog inputs for sensor signals
• 4 channels configurable analog outputs (0‑±10 V, 0‑20 mA / 4‑20 mA) for measured value transmission to PLC / DCS
• 8 optically‑isolated digital inputs, 8 optically‑isolated digital outputs for interlock logic, status feedback and external device triggering
• Internal 24 VDC auxiliary power output (max 0.5 A) for powering external sensors.

4. System commissioning, simulation and self‑diagnosis Step‑by‑step guided parameter setup menu. Built‑in simulation mode for offline system verification without real strip running. Comprehensive self‑diagnosis covers hardware channel faults and sensor failure detection, supporting fast on‑site troubleshooting. Multiple engineering units (mm etc.) are selectable for measured values.
5. Multi‑mode communication for system integration Support VIP Ethernet protocol, RS‑232 serial communication. Connect to Millmate operator unit, ABB AC800M PLC and third‑party automation systems for bidirectional data exchange of set‑points, actual values and alarm information.
