Vibration Analysis Feature

• Vibration Analysis (VA), applied in an industrial or maintenance environment

aims to reduce maintenance costs and equipment downtime by detecting

equipment faults

• To analyze vibrations, accelerometer time domain signal is transferred to

frequency domain for more effective analysis. This is achieved with FFT

• Output of the FFT library

• Maximum frequency of detected vibration

• Amplitude for the frequency

• Motor Status (OK, warning, failure)
