Protect the Potential of Your Machines
Resonances result from design decisions which may or may not be modeled by the designer. Known design decisions include the load shape, material selection, dimensions and physical size. Unknown design decisions include tolerances, assembly processes and motor characteristics. The resonances may change over time because of normal machine wear and tear. This can include applications which use shaft extensions or large loads like winders.
The previous approach to resolving resonances are to detune the regulator gains. This can stop a machine from shrieking and shaking, but it can also decrease the machine’s performance. Over time, this hurts your throughput and slows your reaction time to issues.
An AC drive with adaptive tuning uses advanced analytics to continually look for and detect different types of resonance. The drive can alert operators of issues in real time, so they can quickly act. In more advanced configurations, the drive can use special filters to mitigate resonance instead of detuning the controller.
This ability to autocorrect issues allows you to maintain the high level of performance that you expect. Based on load characteristics, we’ve seen two- to four-times-higher performance when using adaptive tuning.
Also, AC drives with adaptive tuning allow you to monitor resonance over time and schedule repairs, if conditions warrant. This can help you work smarter by addressing issues proactively and during scheduled maintenance windows, rather than abruptly in the middle of production.
