Sepro Robotique Carte CPU G4 board

Sepro Robotique Carte CPU G4 is the main processor board for Sepro’s industrial robot controllers, typically mounted on a CNC or servo‑drive chassis and interfacing with motion modules via CANopen or EtherCAT. Common failure modes include burnt capacitors or solder joints around the power input, degraded MOSFETs in the DC‑DC converters, and firmware corruption that manifests as boot failures or erratic I/O signals. Initial diagnostics should verify the 24 V/48 V supply rails with a multimeter, inspect for visible damage on the board’s voltage regulator traces, and read any stored error codes from the controller’s diagnostic port before proceeding to component‑level testing.[oss-gpt-20b]
