The application research on the FANUC self-diagnostic system in processing the emergency stop fault

摘要

At present, China's CNC machine tool widely used FANUC 0i NC system. the FANUC system can be divided into two parts: the control of servo motor and spindle motor action system and control of auxiliary electrical part of the PMC, PMC uses software to realize the control, can be modified online, with the system fault detection and diagnosis. The emergency stop function is to protect the machine safety. Therefore, timely and effective treatment emergency stop fault is the key to improve the reliability of machine tool, but it caused the emergency stop for many reasons, this article mainly expounds the control principle of emergency stop in the FANUC 0i CNC system; the typical fault example was analyzed, diagnosed and eliminated by PMC. As a result, we put forward some solutions to emergency stop fault.
