4.3.1Fixed Point Definition
Definition
The cam consists of individual cam segments. Under SIMOTION CamTool, you can use fixed points, straight lines, sine curves, arc sine curves and interpolation points as cam segments.
A fixed point is a specified position of the slave axis for a certain position of the master axis. You can specify the velocity and acceleration at the fixed point position.
Notice
With a fixed point, you define a single fixed position. The transitions between adjacent cam segments are optimally calculated by CamTool.
If you want to specify an arbitrary characteristic, you must use interpolation points. The individual interpolation points are connected by CamTool with cubic splines in order to generate a curve specified by the interpolation points which is as exact as possible.
4.3.2Insert fixed point
Requirements
The cam is opened with SIMOTION CamTool.
Insert fixed point
To insert a fixed point:
1.Click in the S diagram (distance diagram) to activate the diagram.
2.Click under menu Cam > Insert at fixed point. The mouse pointer changes.
3.With the changed mouse pointer, click the position in the S diagram (distance diagram) at which you want to insert the fixed point.
