start at the trigger location. If the slider is completely to the right (max samples) the graph will capture data until the trigger point.
Buffer Upload Size
The buffer upload size slider truncates the drive captured data. If the slider is completely to the right (max) the complete buffer will be
uploaded. If the slider is completely to the left, only 1% of the buffer will be uploaded. This parameter does not effect the data capture size, it
only defines how much of the buffer will be uploaded.
3.2.3 Data Group
Data Channel 1 - 4 Select List Boxes
The Channel 1 through Channel 4 list boxes give the user options for parameter display. If parameters with the same units are mapped on
adjacent channels then the graphical display will show these two parameters overlapped on the same x/y axis. If it is desirable to have two
adjacent Channels with the same units mapped to separate axis on the graph then the selection (none) should be used on the channel in
between these two parameters.
Trigger Radio Buttons
Selecting the radio button will cause the graphical capture to trigger the capture off the selected Channel. The “Trigger Level” text box on the
bottom of the display will change units to the selected channel's parameter units. This trigger level may be changed at any time but the change
must be sent to the drive via the Update to RAM or Download button. If a manual trigger is desired, set the channel to None and select the
corresponding trigger radio button. If no trigger is selected the capture will begin when the Run button is clicked and end at the end of the
Sample Rate.
Custom Variable
A Custom Variable text box is only available once the user has selected Custom Variable from the Select list box. This field is used to define
what parameter will be plotted on that channel. The custom variable parameter can be entered two ways: by just typing any custom variable
using the program format for the variable, or click the Popup Variables button and the variable window will open. Then select the variable and
drag it over to the channel custom variable text box.
Trigger Mask List Box
This list box is only available when Drive Inputs or Drive Outputs are selected in the channel select list box and the Trigger radio button is
selected for that channel. The Trigger Mask list box will only list the inputs or outputs for the selected channel parameter.
Trigger Falling Edge Check Box
When the Trigger Falling Edge check box is selected, the trigger is detected when the data transitions below the trigger level. When the Trigger
Falling Edge check box is clear, the trigger is detected when the data transitions above the trigger level.
Trigger Level
This is the level at which the graph is triggered. The “Trigger Level” text box will change units to the selected channel's parameter unit. This
trigger level may be changed at any time but the change must be sent to the drive via the
Update to RAM or Download button.
