Rockwell Automation 1440-VSE02-01RA XM-122 gSE Vibration Module - Manual (Page 96)

Publication GMSI10-UM013D-EN-P - May 2010
86 Configuration Parameters
The XM-122 collects a coast-down trend when the machine speed falls
through the Maximum Speed - 8 RPM, and stops when the machine speed
crosses either the Minimum Speed or the Maximum Speed. The module
collects data when the machine speed is decreasing or increasing during the
coast-down trend (for example, a coast-down restart).
The XM-122 can only store one startup/coast-down trend. Unless the
startup/coast-down trend is latched, the trend data is overwritten with new
data when the next trigger occurs.
The SU/CD trend parameters define the trend data that is collected by the
module during the startup or coast-down of a machine. Use these parameters
to configure the measurements included in the startup and coast-down trend
records, the interval between trend records, and the minimum and maximum
speed limits at which record collection starts and stops.
IMPORTANT
The SU/CD Trend parameters are not included in the EDS
file and cannot be edited using generic configuration tools
such as RSNetWorx for DeviceNet.
SU/CD Trend Parameters
Parameter Name Description Values/Comments
Enable SU/CD Trend Enable/disable the SU/CD trend measurements.
Select to configure the SU/CD trend measurements. Check to enable.
Clear to disable.
Select Measurements Sets the measurements to be collected and stored in
the module.
Note: The Speed measurement is always included in
the startup/coast-down trend.
1 to 16 measurements can be
selected.
Number of Records The maximum number of measurement sets that can
be collected in the trend buffer. The measurement
sets make up the trend data. The Number of Records is
automatically calculated based upon
the number of Trended
Measurements selected.
Latch Enable Determines whether the startup/coast-down trend is
latched or unlatched.
Latched means that subsequent startup/coast-down
trends are ignored after the initial
startup/coast-down. This prevents the trend data
from being overwritten with new data until the
trigger is manually reset (click Reset Trigger
button).
Unlatched means that the startup/coast-down trend
data is overwritten with new data every time the
machine speed crosses into the speed range.
Check means latched
Clear means unlatched
Record Interval The change in speed between consecutive records.
Note: If you enter a Record Interval, the Maximum
Trend Span is automatically updated.
1 to 3600 RPM
