Cam Profile Editor

To open the cam profile The position of a slave axis is mathematically linked to the position of a master axis. Example: A system where two rotating drums turn at a given ratio to each other. A more advanced case of electronic gearing is electronic camming. With electronic camming, a slave axis follows a profile that is a function of the master position. This profile need not be linear but it must be a mathematical function. editor in a new tab of the workspace, double-click a profile in the Project Explorer.

The cam profile editor is used to create and/or modify a profile definition that describes the position Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different. evolution of the cam.

• This evolution is displayed in a 2D graphical format.
• You can add, delete, or modify cam elements which consist of points and lines.
  • Based on those elements and some constraints, the KAS-IDE Kollmorgen Automation Suite - Integrated Development Environment calculates a complete cam shape.
  • See Cam Profile Segment Overview for more information on the segment types.
• Master/Input (X-Axis) and Slave/Output (Y-axis) coordinates can be specified to define the position.
• It is also possible to visualize the velocity For a group of axes this means: In ACS the velocities of the different axes. In MCS and PCS it provides the velocity of the TCP, acceleration A change in velocity over time. Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, acceleration is the rate at which something speeds up or slows down. However, more generally, acceleration is a vector quantity expressing the change with time of the velocity both in magnitude and in direction. See these Wikipedia articles for more information: http://en.wikipedia.org/wiki/Velocity http://en.wikipedia.org/wiki/Euclidean_vector http://en.wikipedia.org/wiki/Rate_(mathematics), and jerk In physics, jerk is the rate of change of acceleration. More precisely, the derivative of acceleration with respect to time. diagrams.

Windows Overview

Figure 2: Cam Profile Editor Main Window

The cam profile editor contains these distinct areas separated by splitters:

1. The cam table (see call out ) displays each element and allows editing of the cam.
2. The Graphical Area for the cam profile
   The upper graph displays a graphical representation of the cam elements
3. The Curve Selection and Color Table allows you to select which plots (velocity, acceleration and jerk) are displayed
4. The Graphical Area for Curves
   The lower graph displays a graphical representation of the velocity, acceleration and jerk plots

• Undo (Ctrl+Z) and Redo (Ctrl+Y) operations are available for any changes you make to the cam profile.

Splitters allow you to resize each part.
