Abstract

The invention provides an FANUC encoder cable tester and a test method, which belong to the technical field of cable testing, can solve sudden and accidental faults of a numerical control machine toolcaused by cable damage, overcome the problems that a traditional testing method is tedious in testing process, large in dynamic and static difference, incapable of testing signal attenuation and interference between signals, not easy to judge, unclear in judgment and the like, and realize efficient maintenance of numerical control equipment. The FANUC encoder cable tester is characterized by comprising a multivibrator, a CD4017 counter chip, a power switch and an LED light emitting diode. The testing method adopting the FANUC encoder cable tester comprises the steps of: adjusting an RP1 potentiometer to enable the multivibrator to generate clock pulses with adjustable frequency, and indicating that a state of a cable to be tested is normal when two sets of LED light emitting diodes are lightened. Compared with the existing examples, the FANUC encoder cable tester can obviously improve the encoder cable maintenance field test efficiency, makes judgment on encoder faults more intuitive,precise and efficient by adjusting the LED lighting period, and can greatly improve the field maintenance efficiency.

Description

technical field [0001] The invention belongs to the technical field of cable testing, and relates to an encoder cable testing instrument. Background technique [0002] There are mainly two types of existing cable testing instruments: [0003] Example 1: Patent No.: CN 106646083 A, Name: A servo encoder cable tester and its testing method. This patented technology aims to solve the traditional Mitsubishi MR-J3-A servo encoder full range of cable detection technology: it is based on the point-to-point interface test of the multimeter. Under the premise of mass testing, the test process is cumbersome and error-prone. It takes a lot of time in the production testing process. The specific operation is to press the SW-SPST trigger key to trigger. After the single-chip microcomputer receives the trigger signal, the IO port of the single-chip microcomputer outputs a high level to drive the connectivity of the detection circuit. Cycle 6 times (the cycle time is fixed), and the cor...
