Fanuc CNC system i/o module detector

Abstract

The invention provides a FANUC numerical control system I / O module detector and belongs to the technical field of the detecting and maintaining of numerical control systems. The I / O module detector includes a switch power supply, an intelligent processor, an encoder, a soft keyboard board desk, an I / O adapter plate, a LCD display and an I / O module. The intelligent processor has a display control signal output end which is connected to a control signal input end of the LCD display. The switch power supply has voltage divided through a first resistor R1 and a second resistor R2, then forms a stable 5V voltage through a voltage-stabilizing tube for supplying power to the intelligent processor and the soft keyboard board desk. The soft keyboard board desk has a signal output end which is connected to a signal input end of the LEC display. The signal input end and the signal output end of the LCD display and a signal output end of the I / O module are all connected to a signal input end of a FANUC system through a 50 flexible printed circuit. The detector has strong anti-interference capability and can respond quickly.

Description

technical field [0001] The invention relates to an I / O module detector of a FANUC numerical control system, and belongs to the technical field of detection and maintenance of a numerical control system. Background technique [0002] Japan's FANUC CNC system has a very high market share in China's CNC machine tool market. Its spindle and servo drive have been developed for several generations, but the external I / O input and output modules remain basically unchanged. For example, the automation system I / O disclosed in the patent CN200810237194.1 O module automatic detection system, according to incomplete statistics, the failure rate of I / O modules accounts for about 12-20%, and there are two main types of failures, that is, the power supply does not work normally and the input and output point signals are abnormal. The maintenance of the power supply is relatively simple, while the maintenance of the latter is more complicated, and its test needs to be connected with the syst...

AI Technical Summary

Problems solved by technology

The maintenance of the power supply is relatively simple, while the maintenance of the latter is more complicated, and its test needs to be connected with the system and PMC

Because the input and output of I / O are defined by the built-in PMC ladder diagram program of FANUC system, and there is not a simple one-to-one correspondence between the PMC ladder diagram program and the input and output of I / O, and FANUC does not use a separate PMC as a programmable The controller PLC module is introduced to the market, and its internal working mechanism is unknown to outsiders, so it is very difficult to test the input and output point signals of the I / O module

At the same time, since the number of I / O terminals used by each CNC machine tool is different, the definition of each terminal is also different, so the difficulty of signal detection of the input and output points of the I / O module is further increased
