Step 5: Configure CAM Profile Data Points
Once these operations are complete, you must configure the CAM profile. A CAM profile is
composed of a series of Points that defines the relationship between the master position
and the slave position. Each point is defined by two coordinates. When viewing the graphical
representation, the Master coordinate represents the horizontal axis and the Slave
coordinate represents the vertical axis, as shown in the next figure.
Begin by double-clicking the profile to open it in the Profile Editor window (see next figure),
which has two editors:
•
Table Editor is similar to a spreadsheet. In the table, each point has its own row with
two columns, one for the Master position and one for the corresponding Slave
position. When a new profile is opened, there are, by default, only two points, a start
point and an end point. The start point is the top point of the table and the end point
is at the bottom.
•
To edit points with the Graphical Editor, click the point on the graph and drag it to
the desire location. (NOTE: The point data in the table editor will update to the new
position.) To perform other tasks in the graphical editor, right-click in the graph and
select the applicable task from the short-cut menu.
The next step is to edit the end point (the bottom point in the table) for the Master and
Slave. In the Table Editor, click in the end point’s Master column and enter the value 50000;
then click in the end point’s Slave column and enter the value 0. (NOTE: As points are added
or changed in the Table Editor, the graph in the Graphical Editor will update accordingly.)
Next, insert an additional point into the Editor table. Right-click in the Master column of the
end point and choose Insert Point from the short-cut menu (shown it the next figure). A new
row is added above the end point row, specifying a new point with master and slave values,
by default, midway (25000 and 0, respectively) between the values of the two existing
adjacent (above and below) points. Change the values for this point to 47500 for the Master
and 11000 for the Slave. To change a point value, click it, type in the new number, then
either press the Enter key, or click outside of the table.
To change the Curve-Fit order, click the Curve-Fit column, then select the Curve-Fit Order
in the Property Inspector window. Also, a profile can be split into multiple sectors or
multiple sectors merged into one by right clicking on the Curve-Fit display and choosing
from the short-cut menu.
Note: A CAM profile is limited to 400 points if it contains second or third order sectors. A CAM profile is
limited to 5000 points if it only contains first order sectors.
