TracesTraces refer to the actual signal data plot(s) generated on a display pane. The Traces menu item may be selected either by clicking on Pane / Traces in the pull-down menu, or by clicking on the Traces button on the main display.
The following "Select Traces Set" panel will appear:
The following table provides the trace descriptions for the Select Traces From This List field:
On the left side of the panel are listed some of the possible signal data which can be traced. They are selected by clicking with the mouse, then clicking on the Add==> button below.
Click on the signal data to be traced , then on the Add==> button. The signal data will be added to the Trace Set for Pane list.
NOTE: Motion Scope is defaulted to autoscale all of the traces selected unless otherwise specified. To turn off autoscale, go to the Manual Scaling section. Trace Ordering – Once a list is defined in the "Trace Set for Pane" window, you may order the arrangement by using the Trace Ordering switch. There are three menu items: UserName – Orders the list by user name. MapName – Orders the list by map name. Address – Orders the list by memory address (as ordered within the controller's firmware memory). TIP: click this menu item again to reverse the order.
Trace Ordering menu items arrange signal data on the Trace Set for Pane window by user name, map name, or memory address. Modify Trace menu items create, edit and close individual traces. These menu items are accessed on the right side of the Select Traces Set panel:
New and Edit – Clicking on either the New or Edit button displays the Edit Trace Properties panel. If no trace is currently listed or selected within the "Trace Set for Pane" window, only the New button may be used.
Name – Name assigned to the new or edited trace. Trace names can be assigned to correlate to specific axes, such as "X," "Y," etc. Address – Hexadecimal memory address to be assigned
to the selected trace. In the example below, SystemData.SampleCounter is shown on the VM3 screen with its hexadecimal address. When this address (0x00028010) is entered into the Address field of the Edit Traces Properties window, it may be plotted on the Motion Scope grid. The data's name (SystemData.SampleCounter) is manually entered into the Name field. Configure the Trigger window, then plot the data. Notice that the plot of SystemData.SampleCounter, which records time, is a constantly increasing line.
Bitmasking – Allows bitmasking of current trace address. The following fields are used: Masking Enabled – When enabled, the data is masked. Mask-- Bit pattern to be masked (bitwise ANDed with mask). Normalize Right – If a Mask has zeros in its lower-order bit(s), the data value is shifted to the right. This is especially convenient for viewing binary, two-state values. Data type – Specifies the data type of the value stored at the Address. The following data types are selectable: long – Data is a long integer (32 bits). float – Data is a floating decimal point value (32 bits). unsigned long – Data is an unsigned, long integer (32 bits). Display as hex – When selected, data stored at the Address is displayed in hexadecimal form. If not selected, data stored at the Address is displayed in its default format. Units – Units applied to the vertical (Y) axis of the display pane. The following units are selectable: Counts – Encoder counts. Counts/sec – Encoder counts per second. MilliSecs – Milliseconds. MilliVolts – Millivolts. None – No units are applied to the vertical axis. OK – Enters settings and closes the Edit Trace Properties panel. Cancel – Closes the Edit Trace Properties panel without changing settings. Note Demo traces (available from the Pane / Mode menu item) cannot be edited. Status Banding
The Status Banding menu item within the "Select Traces Set" panel turns on-off separate trace bands at the top of the pane for monitoring NEAR_TARGET and SETTLED status on a single axis. Two color schemes are used: green = FALSE; red = TRUE.
In above, the Status Banding menu item has been enabled
for the axis indicated by the Axis field. Command velocity (trapezoidal
profile) reveals motor movement. As the command position (curved profile)
crosses the NEAR_TARGET position value at Motion Scope is defaulted to autoscale all of the traces selected unless otherwise specified. To turn off the autoscale feature, you will need to individually modify each trace you do not want Motion Scope to autoscale. Click the Traces button. In the "Select Traces Set" window. Select a trace and click the Edit button.
Make sure you clear both auto scaling check boxes.
Repeat for any traces you want to scale manually. When scaling manually, use the YScale and YOffset for adjusting scaling. Displaying Drive Monitor Fields in Motion Scope
Group Highlighted TracesWhen displaying multiple signal data plot(s) on a display pane, it may be helpful to group certain signal data plots together so that they are displayed on the same scale. Here are two graphs where the traces are NOT grouped together. Notice that the scale on each plot is different. The scale changes depending on which trace is chosen (highlighted in white).
It would be easier to interpret the relationship between Actual and Command Positions if the traces were plotted on the same scale. This option can be set in MotionScope by using the Edit Trace Group feature. The graph below shows both traces using the same scale, because they were grouped together in MotionScope.
Follow the steps below to group two or more traces together.1. Click on the Traces button.
The Select Traces Set window will appear. (see below) 2. Add the desired traces to the Traces Set for Pane listbox.
3. Select the traces that you would like to group together and click the Add button under Group Highlighted Traces. The Edit Trace Group window will appear. Enter a name for the group (ex: positions) and click OK.
4. You will notice that the group called "positions" is listed in the Group highlighted Traces listbox. If you click on the group, the traces associated with the group will be highlighted in the Trace Set for Pane listbox. In the example below, the Axis 0 Command Position and Axis 0 Actual Position traces are grouped together in the "positions" group. 5. Click OK.
6. When the plot is graphed, you will notice that Axis 0 Command Position and Axis 0 Actual Position are graphed on the same scale.
Follow the steps to modify a set of traces belonging to a particular group:1. From the Select Traces Set window, select the Group to modify in the Group highlighted Traces listbox. Notice that the current Group member traces will be highlighted in the Trace Set for Pane listbox. In this example, the Axis 0 Command Position and Axis 0 Actual Position traces are associated with the positions group. 2. Using the mouse and the Control and/or Shift keys, select or deselect traces in the Trace Set for Pane listbox to create the new set to be associated with the group selected in the Group highlighted Traces listbox. In this example, we want the positions group to include Axis 0 Command Position and Axis Command Velocity traces and disassociate the Axis 0 Actual Position trace. 3. Press the Modify button to override the old grouping and associate the currently selected traces with the highlighted group: |

the NEAR_TARGET band (topmost band) changes color from green-FALSE, to red-TRUE.
(Meaning, the position of the axis is now within the NEAR_TARGET envelope
of the target position.) As the axis reaches the target position, it enters
the IN_FINE envelope at 
,
and the lower (SETTLED) status band changes color from green-FALSE, to
red-TRUE.
