CNC Tech Journal Target Control: FANUC 0T Model A, B, & C (Lathe) A critical function for machine reliability and safety

The Fanuc 0T is one of the most widely used CNC lathe controls in history. A critical function for machine reliability and safety is the (often called "zero return" or "home position"). On the Fanuc 0T, reference positions are not hard-coded; they are defined by a combination of parameters, deceleration switches, and position coder signals. If your machine drifts from its correct home position, crashes on zero return, or requires constant adjustment, tuning the reference point parameters is the solution.

When optimized correctly, a Fanuc 0T will return to the exact same reference point within 0.002 mm cycle after cycle, greatly improving part consistency and reducing setup time.
