The data volumes generated in industrial production are huge. For the quality assurance of electric drives just off the line, the test benches alone record data for thousands of parameters. However, these data, together with information from production itself, are opening up opportunities to create a more efficient overall process and maximum reliability for it. Ultimately, at end-of-the-line testing, the test benches deliver not only the final “OK” or “Not OK” test result, but also all kinds of raw data. This gives operators detailed insight into the product and the production workflows.
