Configuring the Ultra5000 Drive Chapter 4
Properties Pane
The Properties pane, on the top left of the cam table, has these parameters and
command buttons.
Parameter Description
Name The file name used to store the cam table. The name must end
in .cam.
Length The input value in counts of the last point in the cam table.
When the length is changed, all of the input values in the cam
table (and velocities if necessary) are adjusted to maintain the
same overall cam shape.
Position Scale Scales in counts the positions defined in the cam table. The
initial default value for Position Scale is 1000 counts. This does
not limit the positions that can be created in the table. However,
when the Position Scale is changed, the positions of all points in
the table are adjusted according to the ratio of the new and old
position scales. For example, if Position Scale is changed from
1000 to 2000, a position of 600 counts would become 1200
counts.
Mode Linear: This type of cam executes with linear (first order) curve
segments. Velocity discontinuities are likely with this type of
cam. However, this type of cam may be most appropriate for
cam tables imported from a CSV file with lots of points.
Polynomial: This type of cam executes with 5th order curve
segments. There are no discontinuities in velocity or
acceleration if all segments have polynomial type. If the cam
has adjacent linear segments, then there will be discontinuities
in velocity.
Command Description
Save Saves the current cam definition to a file on the associated
drive.
Close Closes the cam table editing window.
Note: If the cam table has been changed but not saved,
Ultraware software prompts the user with the opportunity to
save the cam file to the drive.
Help Displays the online help topic for the cam table editing window.
