How to configure condition-based monitoring with inverters in just a few steps

Condition monitoring with frequency inverter - this is how it works

Condition monitoring – also known as condition-based monitoring (CBM) – is one of the important trends in automation and plant engineering. Users use condition-based monitoring with converters for lower maintenance costs, higher availability and, last but not least, to further optimize existing processes.

All this is based on systematic and reliable acquisition of condition data in the drives of the production lines. But how much effort is required to collect such data and, for example, to configure the frequency inverters so that they act as sensors in the plant?

Set up condition-based monitoring with inverter step by step

Danfoss Drives shows that this can be done quickly and easily with the right tools, in a video on setting up the CBM using VLT® Motion Control Software MCT 10. This Windows-based software uses a plug-in and additional parameter groups in VLT® frequency inverters with CBM-supporting firmware to activate and parameterize the functions by license code in just a few steps. Here, only vibration monitoring requires external hardware in the form of a vibration sensor to collect the data and issue appropriate warnings and alarms based on the evaluation of the measurements. In the video you can see the procedure to configure and parameterize the variables and limit values. The video is in English, but German subtitles are available.

How does an inverter learn?

CBM experts Jörg Dannehl and Holger Schmidt explain how and why a frequency inverter learns and what is behind condition-based monitoring with inverters in the first episode of Drehmoment – Der Antriebspodcast. The frequency converter gets a new control card and thus no longer only controls the drive, but also detects errors. It is important that the inverter learns the typical patterns of the plant after commissioning. Trained with sufficient data, it then starts monitoring. From this moment on, a traffic light system warns the user in real time when errors occur. Listen in and take knowledge with you into your everyday work!
