FANUC A02B‑0348‑B502 0i‑MF Plus CNC Control Unit

Product Description

The A02B‑0348‑B502 is a FANUC Series 0i‑MF Plus integrated CNC controller with built‑in LCD display and MDI membrane keypad. It adopts thin panel‑mount structure and integrates CNC CPU, graphic processor, PLC and communication circuits into one unit. As the core human‑machine interface and numerical control host for milling‑type machine tools, it connects to FANUC servo drives and I/O modules, and is built to endure dust, vibration and wide temperature fluctuations on workshop floors.

• Execute G‑code machining programs and multi‑axis coordinated motion control
• Integrated LCD and MDI keypad for manual data input, program editing and graphic simulation
• Built‑in PMC ladder logic to manage machine tool auxiliary actions and safety interlocks
• Servo HRV+ control, intelligent acceleration/deceleration and backlash compensation for high precision machining
• Ethernet and USB interfaces for program upload/download, data backup and remote diagnosis
• Real‑time monitoring of spindle, axis load, alarm messages and maintenance information
• iHMI intelligent operation interface with multilingual display and tool life management

Application Scenarios

• Vertical and horizontal machining centers and milling CNC machines
