What if, rather than scrambling to resolve asset failures when they happen out of the blue, you could see them coming and make plans to address them? You would probably herald in greater peace of mind, with less agonizing over surprise failures and the unplanned downtime that comes with them. You would also most likely cut costs by reducing your spending on maintenance and replacement parts.
Today, a “countdown to failure” capability for your production assets is something you can deploy using AC drives that have advanced, built-in predictive maintenance.
Agnostic + Adaptive = Accurate
Predictive maintenance can offer different levels of accuracy.
For example, some products are configured to make certain assumptions, such as the operating conditions in which they’ll be used.
However, if a product is configured for the hottest possible conditions but used in a cooled facility, then it likely will alert users of servicing or replacement needs sooner than they’re actually required. And while that’s a better maintenance approach than waiting for assets to fail, it doesn’t allow you to get the most performance or value from your capital investments.
New AC drives with predictive maintenance are configured with agnostic algorithms. This means the drive will make no assumptions about the application or operating conditions in which you deploy it.
Instead, the drive spends its first 30 days of operation learning its applications stresses. It uses built-in sensors to monitor stressors like temperature, voltage, current and speed. It then uses models to convert those stressors into rate-of-life consumption data for critical components such as fans and capacitors.
