Tab: Cam
In this graphical editor, the cam graphs are defined. At any time, you can switch between the graphical editor and the alternative tabular editor (Tab: Cam Table).
The curves of four graphs are displayed in the editor:
Slave position (black)
Slave velocity (blue)
Slave acceleration (green)
Slave jerk (yellow)
The horizontal axis of all four coordinate systems shows the range of the master values ([0,360]). The vertical axis in the position diagram shows the value range that is defined in the cam properties. The vertical axis of velocity, acceleration, and jerk is scaled automatically.
A new inserted cam is assigned with default values. It consists of four points that subdivide the graph into three sections: [0,120], [120,240], and [240,360]. Each of the interval parts of the cam graphs is type Poly5 (5th degree polynomial).
You can modify all curves. As velocity, acceleration, and jerk are derived curves, changes to one graph causes changes to the other graphs.
You change the height of the diagram by moving the horizontal separation bars.
| Select a line in the table by using this tool. Selected points are deleted by pressing the Del key. |
| Add new points with this tool. Click the insertion point in the diagram. The graph is then adapted automatically so that its curve runs through the new inserted point. |
X | X-position of the slave axis |
Y | Y-position of the slave axis |
V | Velocity of the slave axis |
A | Acceleration of the slave axis |
J | Jerk of the slave axis |
