Configuring the Ultra5000 Drive Chapter 4
Position Profile Pane
The Position Profile Pane on the top right, displays the cam positions in an
editable graph. The cam table points in this view can be dragged to adjust both
their Input and Position values.
Right-click this pane to open a context menu in which you can modify the
position profile with these commands.
Velocity Profile Pane
The Velocity Profile Pane, on the right but below the Position Profile Pane,
displays the cam velocity in an editable graph, but only the Velocity values may be
adjusted in this graph, not the Input values. If the end point of the velocity profile
is adjusted, the first point’s velocity is automatically adjusted to have the same
value.
The velocity profile is only editable for a polynomial mode cam. For a linear
mode cam, the velocity of each segment is entirely determined by the location of
points in the Position Profile. Velocities are displayed in units of output position
counts per input count. To determine the actual output velocity of the cam, in
counts per second, the velocities from the graph must be multiplied by the actual
input velocity in counts per second.
Parameter Description
Add Point Adds a point to the cam table at the location under the mouse
cursor.
Delete Point Deletes the point under the mouse cursor from the cam table.
Dwell Segment Sets the velocity of the cam segment under the cursor to have
zero velocity. The position of the segment end point is adjusted
to be equal to the beginning point of the segment.
Constant Velocity Segment Sets the velocity of the cam segment under the cursor to a
constant value. The positions of the segment endpoints are not
adjusted. The velocity required to move from the beginning of
the segment to the end is calculated as (change in Position) /
(change in Input). This velocity is then set at the segment end
points.
