Table Window
The values for the movement section are displayed in the table window:
Table header |
Description |
---|---|
Function |
Indicates the function type (see function types) |
Velocity |
absolute velocity value |
Velocity [%] |
percentage velocity value |
Voltage [%] |
percentage voltage |
Range |
absolute value of the transition range |
Range[%] |
percentage value of the transition range |
The values can be changed through the keyboard. The percentage and absolute values are directly connected, so that changing one of them leads to an immediate corresponding change in the other (once the return key has been pressed or the box has been left).
Function Types
In addition to the standard types (synchronous/automatic), which can be changed by command on the graph, the function type can also be modified in the combobox. When the combobox - or a field in the first column - is first clicked, a rectangle is temporarily shown in the position window, with the initial and end points of the section at its corners. As soon as another field in the table window is activated, either the rectangle for this one is shown, or no rectangle is displayed at all.
The types correspond to those of VDI Guideline 2143; additionally, there are the cubic splines, with the boundary conditions of natural, tangential and periodical.
Type |
Description |
Boundary condition |
---|---|---|
Synchronous |
Synchronous movement (constant transmission ratio between slave and master, corresponds to normalised velocity) |
Constant velocity v, acceleration a=0 |
Automatic |
Automatic adaptation to the boundary values (velocity, acceleration) | |
Spline |
Internal section of a cubic spline | |
Spline Natural |
Initial or end section of a natural cubic spline |
a=0 |
Spline Tangential |
Initial or end section of a tangential cubic spline | |
Spline Periodic |
Initial or end section of a cyclic cubic spline |
Changing the type of spline at the first point implies that the spline type as a whole is changed, including that of the end point.
