Abstract

The short circuit between the terminals tests the output waveform or the number of pulses. Therefore, the accuracy of the measurement angle decreases during inconvenient and manual rotation operation. The measurement method and procedure differ depending on the pulse type and gray code type. Therefore, the above problem is further aggravated, and it is difficult to recognize a defective place because it is difficult to solve the problem that is difficult to identify the cause.

본 발명은 테스트하고자 하는 엔코더 타입에 따라 테스트 모드를 정하여 해당 엔코더의 테스트 모드하에서 초기 테스트 위치를 잡고 회로패턴간의 단락여부를 판별하며, 기 입력된 표준코드 또는 기준 펄스수와 마이콤 구동제어에 따라 기구적으로 엔코더의 출력코드 또는 펄스수를 검증하여 불량상황을 정확히 표시해주므로서 자동적인 테스트 수행이 가능하고 이에 따른 테스트 작업의 편리함과 불량원인의 용이한 파악 및 그 후속조치에 신속히 대응할 수 있도록 한 것으로 엔코더 테스트 수단에 적용한다.The present invention determines the test mode according to the encoder type to be tested, holds the initial test position under the test mode of the corresponding encoder, and determines whether there is a short circuit between the circuit patterns, and according to the input standard code or reference pulse number and the microcomputer drive control. By verifying the encoder's output code or number of pulses and displaying the exact status of defects, it is possible to perform automatic test and it is possible to promptly respond to the convenience of the test work, easy identification of the cause of the defects, and the subsequent actions. Applies to encoder test means.
