Rockwell Automation 1440-VST02-01RA XM-120 Eccentricity Module - Manual (Page 53)

Publication GMSI10-UM010C-EN-P - May 2010
Configuration Parameters 45
Measurement Parameters Eccentricity Measurement Parameters
Use these parameters to configure the engineering units and update rate for
the eccentricity measurements. There are two instances of the eccentricity
measurement parameters, one for each channel.
Waveform Parameters
There are two instances of the waveform parameters, one for each channel.
Use these parameters to set up the waveform measurements.
TIP
The Eccentricity Update Rate parameter is for
installations where the tachometer signal is not available.
Eccentricity Measurement Parameters
Parameter Name Description Values/Comments
Eccentricity Units The data units of the measured values. Options: mils
µm
Eccentricity Update Rate The update rate for the eccentricity, min gap, and
max gap measurements. Enter a value from 1 to 255 seconds.
Note: This value is used when the
tachometer is disabled (Pulses Per
Revolution set to zero) or a fault
condition exists on the tachometer
channel.
Waveform Parameters
Parameter Name Description Values/Comments
Waveform Period The total period of the waveform measurement. Seconds
Number of Points The number of samples in the waveform
measurement. Options: 256
512
