The main content is to collect all torque information of servo motor by computer server, through records and analysis, to build equipment early-warning system. After calculation and statistics, we can set up device torque data sheets, and the limit torque value can be defined. Through programs and alarm system, we can achieve early-warning function. Also we can monitor equipment lifecycle, and do preventive maintenance or repair before equipment fails. Eventually to reduce unexpected failures, increasing the company's competitiveness.
