Fanuc alarm codes can be found on the website for HelmanCNC, a website for computer numeric control (CNC) programming tools. Fanuc Spares out of Great Britain also has a list of several codes and faults for Fanuc machinery. Alarm codes begin with zero and rise up to 976 before skipping to 4,500 and going up to 5,450.
A list of alarm codes is also located in the equipment's original manual, copies of which can also be found on the Fanuc Spares website. Fanuc is one of the largest suppliers of industrial robotics in the world with offices in the United States, Europe and Japan. Machines used in the manufacturing process include automatic drill presses, lathes, vertical machines and forges.
Alarm codes alert users to something wrong with the machinery, materials or process. When a measurement or data is not what the computer expects, an alarm code is interpreted at the control panel for action. Users can then determine what to do next, either by shutting the process down or putting in another command to solve the dilemma.
Fanuc was founded in 1956 in Japan by Dr. Seiuemon Inaba, and its machinery is known for bright yellow colors. The company boasts more than 250,000 industrial robots working worldwide with more than 2.4 million CNCs. Inaba still serves as FANUC's honorary chairman in his advanced age.
