5.4.1.5.7 Characteristic values
The following applies to all characteristic value module registers:
•
All calculated characteristic values can be locked using RequestDataLock01, which allows all registers to
be read in a consistent manner.
The following characteristic values can be read from the X90CM480 for each channel:
Characteristic values
Description
"PeakHighFrequency"
Absolute maximum of the high-pass filtered input signal.
"CrestFactorHighFrequency"
Ratio of the absolute maximum to the RMS value of the high-pass filtered input signal
"Vdi3832KtHighFrequency"
Ratio between the reference values and the currently measured values of the high-pass filtered input signal per the
VDI 3832 guideline
"PeakRaw"
Peak value (absolute) of the input signal up to the configured maximum frequency
"CrestFactorRaw"
Ratio of the absolute maximum to the RMS value of the input signal up to the configured maximum frequency
"SkewnessRaw"
Skewness (third statistical moment) of the input signal up to the configured maximum frequency
"KurtosisRaw"
Kurtosis (fourth statistical moment) of the input signal up to the configured maximum frequency
"Vdi3832KtRaw"
Relationship of the reference value to the currently measured value of the input signal per the VDI 3832 guideline.
"RmsHighFrequency"
RMS value of the high-pass filtered input signal
"RmsRaw"
RMS value of the input signal up to the configured maximum frequency
"RmsAccRaw"
RMS value of the input signal's acceleration from the configured minimum frequency up to the configured maximum
frequency
"RmsVelRaw"
RMS value of the input signal's speed from the configured minimum frequency up to the configured maximum frequency
1)
"Iso10816"
RMS value of the velocity in the frequency domain 10 Hz to 1 kHz per ISO 10816
"RmsAccEnvelope"
RMS value of the acceleration of the input signal's envelope from the configured minimum frequency up to the configured
maximum frequency
"RmsVelEnvelope"
RMS value of the speed of the input signal's envelope from the configured minimum frequency up to the configured
maximum frequency

1)
This is only calculated if the EnableVelocityCalculation bit (configuration in register
"SensorConfig" on page 158
) is set for the respective channel; otherwise,
0 is output.
