7 Amplitude Ripple
(Sun Sum units)
MFG
Only
Reports the ripple in the Sin Sum amplitude
values. Excludes the neighborhood of the
Home notch (a distance of +/- 50 samples from
the Home notch min location.
8 Max Position Ripple
(mpts)
MFG
Only
Reports the max variation in the reported delta
position between samples over the revolution.
Y-axis Geometry
Rotates the drum at a constant velocity and samples the Y-axis position. Uses the data to
determine Y-axis motor and drum vibration and the most significant other vibrational frequencies.

0 Drum Normalized
FFT Power (none)
MFG
Only
Reports the normalized FFT power amplitude
of the drum frequency. The normalized value is
generated by dividing the drum FFT power by
1.0xE13.
1 Drum Frequency
(hz)
MFG
Only
Reports the current drum frequency.
2 Motor FFT Power
Ratio (none)
MFG
Only
Reports the ration of the FFT power amplitude
of the motor frequency to the FFT power
amplitude of the drum frequency.
3 Motor Frequency
(hz)
MFG
Only
Reports the current motor frequency.
4 FFT Power Ratio 1
(none)
MFG
Only
Reports the ratio of the FFT power amplitude
of the most powerful FFT frequency (not
including the drum or motor), to the FFT power
amplitude of the drum frequency.
5 Frequency 1
Frequency (hz)
MFG
Only
Reports the frequency of the most powerful
FFT frequency (not including the drum or
motor).
6 FFT Power Ratio 2
(none)
MFG
Only
Reports the ratio of the FFT power amplitude
of the second most powerful FFT frequency
(not including the drum or motor), to the FFT
power amplitude of the drum frequency.
Y-axis Encoder (Continued)
Uses the sine and cosine sum data to determine the characteristics of the encoder disk and
encoder sensors.
