4-8 A Brief Look at Software 929895 ZonicBook/618E

eZ-Rotate Capabilities

Displays: Time waveform, machine speed curve, waterfall, contour, spectrogram, and Bode plots of cursor

amplitude or phase; overlay machine speed curves for speed profiling along a machine or line; zoom in and

autoscale any plot; change the orientation of a waterfall plot

Cursors: Single or multiple independent cursors; X or Z axis tracking; time, spectrum number, RPM, or

order tracking

Analysis

• Tachometer Processing creates a smoothed machine speed curve from even noisy tachometer

(pulse or DC) or encoder signals.

• Waterfall Analysis creates a spectral waterfall plot of the data. You can also display the plot in

orders of running speed if there is a tachometer signal.

• Computed Order Tracking creates a Bode plot of the amplitude and phase of the data at each

order as a function of time, RPM, and frequency by resampling at a constant shaft angle

increment instead of a constant time interval.

• Torsional Analysis creates a spectral waterfall plot of the torsional vibration from a high-

resolution tachometer or encoder signal.

• A, B, and C Weighting for acoustic analysis, Whole Body and Hand-Arm Weighting for

comfort analysis.

• Integration and Differentiation display the results in acceleration, velocity, or displacement.

Reporting

• Copy Plots and Data from eZ-RotatePlus seamlessly into other Microsoft® program (such as

Word®, Excel®, and PowerPoint®); data may be operated on in Excel.

• Export Data to MATLAB® and Universal File Format files. You can export the entire channel

of data, or extract a section of the data to speed analysis on just the part of interest.

• Operating Deflection Shape analysis is available by exporting order-based data from

eZ-RotatePlus to ME scope.

eZ-RotatePlus Capabilities

eZ-RotatePlus includes all of the capabilities of Rotate, plus the following features:

Cursors: rolling-element bearing, harmonic, sideband, gearbox, and planetary gearbox cursors

Analysis

• RPM from Waterfall analysis creates a smoothed machine speed curve from the data without a

tachometer signal

• Order Normalization cancels the effect of frequency smearing across spectral bins when the

shaft speed is changing rapidly (high slew rate) by resampling triggered by tachometer speed.

You can zoom in on an order range with a greatly enhanced resolution

• Millstrum Analysis (Cepstrum) identifies families of harmonics and sidebands, particularly

useful on noisy signals with low-amplitude harmonics or sidebands characteristic of early-stage

bearing or gearbox defects

• Advanced Torsional, torque, windup and belt dynamics and slippage analysis

• Synchronous Averaging, envelope detection and phase demodulation
