4.8 Optimizing a Cam
Parameters
You can specify the parameters of the interpolation curve for the transition here.
You can set the following parameters:

| Field/button | Explanation/instructions |
Jerk at boundary point |
| ||
(allow interpolation by target device |
| ||
deactivated) |
|
| |
(for 6th degree polynomial) |
| ||
| Automatically | If you activate Automatically, the jerk value at the boundary points is | |
|
|
| calculated by the system. A polynomial of the 5th degree is used for the |
|
|
| calculation. |

| Left |
| If you activate Left, you can specify the jerk at the left boundary point of |
| (automatically deactivated) | the interpolation curve. Enter the jerk value in the input field. | |
| Right |
| If you activate Right, you can specify the jerk at the right boundary point |
| (automatically deactivated) | of the interpolation curve. Enter the jerk value in the input field. | |
| (Jerk value) | If you activate the option Left or the option Right, you can enter the jerk | |
| (automatically deactivated) | value here. | |
|
|
| Note: |
|
|
| To specify an absolute jerk value, you must select an absolute master |
|
|
| velocity for calculations in the Simulation Settings window. |
Curve point of inflexion |
| ||
(allow interpolation by target device |
| ||
deactivated) |
|
| |
(for inclined sine curve) |
| ||
(for modified sine curve) |
| ||
(for modified acceleration trapezoid) |
| ||
(for harmonic combination) |
| ||
| Valid values are between 0 and 1 | You can enter the turning point of the curve here. | |
| Optimum value | If you click this button, the optimum value for the turning point of the | |
|
|
| curve is calculated by the system and entered under Valid values are |
|
|
| between 0 and 1. |
