Test Automation of Motor Over Temperature Protection Extension Module of Drive

Abstract

In industries, for releasing any product into the market, various stages of testing procedure must be done on the product to test its functionality and reliability. The testing procedure has to be frequent and accurate enough to enable early defect detection. Manual testing procedures are time-consuming, need more human resources at the place of testing, have no concept of documentation, and have more chances of human errors. To overcome the variously described limitations of manual testing, test automation is a key tool for providing prompt feedback, tracking of developed firmware versions time-to-time and reducing the tester’s efforts to perform tests task repetitively. The main goal is to speed up test execution cycles and improve the accuracy as well as the performance of the module for end-user customer satisfaction. The proposed system works based on replacing the potentiometer with a relay configuration controlled by the digital output signal of the Programmable Logical Controller and Automated Test Framework. The study describes the transition from manual testing of modules with complex setup environments to automatic testing of modules with implemented hardware changes.
