System compatibility

Compatibility description: 502-03518-03 belongs to Fives Group CNC motion control board family. Compatible with Fives Group main CPU, servo interface boards and encoder feedback modules. Widely deployed on heavy Fives Group horizontal boring mills.

Function

Function description: 502-03518-03 is dedicated axis motion control board manufactured by Fives Group. It undertakes real-time multi-axis interpolation and closed-loop position control, offloading motion computation from the main CPU. It compares target position with encoder feedback continuously and generates velocity commands for servo control, ensuring high-precision contour machining. The onboard watchdog circuit monitors runtime status and triggers alarm when abnormality occurs. It is legacy axis motion control spare for heavy CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off rack +5V backplane power. Insert 502-03518-03 board into rack slot and secure gold finger connector. Power on rack, verify RUN and AXIS LED indicators, load axis parameters, perform servo tuning, test single-axis jog and multi-axis contour machining function.

Interface

Interface list: Backplane gold finger connector,on-board POWER / RUN / AXIS / FAULT LED indicators for Fives Group 502-03518-03.

Diagnostic

Troubleshooting: Axis jogging invalid: Check backplane contact condition, axis parameter setting or bus communication fault. FAULT LED lit: Watchdog timeout, position calculation error or backplane communication failure. Contour machining deviation: Improper servo tuning, aging timing component or encoder signal interference.
