Can the 'tach' data be explained? #1

The paper 'Processing for Improved Spectral Analysis' and' Wind turbine high-speed shaft bearings health prognosis through a spectral Kurtosis-derived indices and SVR 'clearly pointed out that the axial velocity variation waveform within 6s time fluctuated around 30Hz with time variation. I find it strange that in the data given, the 'tach' data in the 50 days are all constant acceleration data, I think this tach data may not be the shaft speed, looking forward to your reply on this issue, thank you!!

The resulting tach waveform is shown below
