Fanuc

Fanuc's legacy O series — including the OT (turning) and OM (milling) variants — remains on many older machines in UK workshops. These controls date from the 1980s and 1990s and are still encountered on machines that are economically viable to maintain. Battery-backed memory loss, CRT display failures, and worn membrane keypads are common issues on these older platforms.

The 0i series — particularly the 0i-Mate and 0i-MD — became the workhorse of UK CNC workshops from the early 2000s onwards, found on machines from XYZ, Hardinge, DMG, and Wasino. The 0i-MODEL F Plus is the current version, featuring the iHMI intelligent Human Machine Interface with a capacitive touchscreen display. Larger facilities will also encounter the Series 16i, 18i, and 21i controls on multi-axis machining centre applications — Mazak, Mori Seiki, and similar brands.

Fanuc's current flagship platforms include the 30i/31i/32i-MODEL B Plus with iHMI touchscreen — featuring a 21.5-inch capacitive touch panel designed for factory environments — and the brand-new Series 500i-A, introduced at IMTS 2024 with dual-engine architecture delivering 2.7 times the processing power of previous generations and integrated 5-axis technology.

Common fault scenarios across all Fanuc platforms include battery depletion causing absolute position loss, servo amplifier READY faults (SV0401 series), overtravel alarms following power interruptions, and parameter corruption after control crashes. The Fanuc alarm code structure — SV, SP, OT, and P/S series — provides a reliable starting point for systematic diagnosis regardless of which generation of control is in front of you.

I carry common Fanuc spare parts including batteries, fuses, and I/O modules, and have access to drives and amplifier modules through specialist suppliers for longer lead-time items.
