Curves Graph

Velocity (the first derivative), acceleration (the second derivative) and jerkIn physics, jerk is the rate of change of acceleration; more precisely, the derivative of acceleration with respect to time (the third derivative) curves are displayed in the lower graph. All plots are displayed by default.

Figure 6-21: Curves Graph

With the check boxes in the Curve selection table shown in Curve Selection Table, you can select or clear each individual curve that you want to be displayed.

The Y-scale of the Curves graph is adjusted to display the Y-scale of the selected curve in the Curve Selection Table. The color of the Y-axis scale "tick" lines is also changed to match the color code of the selected curve.

Y axis	Unit	Description
Vel	Units/Time	Being the rate of change of position, the velocity is the ratio between the slave and master derivatives
Accel	Units/Time2	Rate of change of velocity with time
JerkIn physics, jerk is the rate of change of acceleration; more precisely, the derivative of acceleration with respect to time	Units/Time3	Rate of change of acceleration; more precisely, the derivative of acceleration with respect to time

In general the numbers relate to how the Y-axis positions (Cam Output) change with respect to the X-axis positions (CAMinput).

 

The zoom and pan functions, when performed on the cam profile graph, are duplicated in the Curves graph.
Zoom and pan functions are not available when the cursor is in the curves graph.
