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.
