3005

Invalid Machining Start Point

Fanuc · Series 0i Manual Guide

What does 3005 mean?

This P/S alarm indicates that the machining start point defined in the program is invalid. This could be due to a coordinate outside the work envelope, an unreachable point, or a point that interferes with existing geometry, preventing the machining cycle from initiating correctly.

Common Causes

  • The programmed starting coordinates for machining are outside valid ranges.
  • Initial tool position is obstructed or in an unsafe location.
  • Invalid G-code command for initiating a machining operation.
  • Error in setting up the absolute or incremental positioning system (e.g., P2-02).
