Why do Drives fail?
A drive, any drive, could theoretically last for a lifetime, but only if properly taken care of. Modern variable-speed drives (VSDs) are exceptionally reliable these days, but they’re not indestructible. That said, if you notice similar persistent or repeated trips in a VSD, then chances are that the drive isn’t actually the problem. If such trips are ignored (eg over temperature), they can sometimes result in the failure of the drive.
A drive outage can have serious implications on your application and so it’s important to learn what you can do to prevent a failure.
Our very own Alan Jones, as a leading UK expert on ABB drives service and maintenance, was asked by ABB to present a video explaining the reasons behind drive failure and what you can do to prevent it.
