Column Description
Master/In

The time is located in the Master/In column.

It is the X-axis of the cam profile graph.

Slave/Out

The positionClosed 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. is located in the Slave/Out column.

It is the Y-axis of the cam profile graph.

Type

The Type column defines whether this element is a point or a line.

  • If the element is a line, In/Out specifies the start point of the line.
  • The next element in the table defines the end of the line.
  • The last element type in the table cannot be changed, since a line cannot exist as the last element.
Vel

The VelocityClosed 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 of the current element (first derivative).

Accel

The AccelerationClosed 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) of the current element (second derivative).

Cyclic Cam Element

Cyclic Selection

If the Cyclic check box is selected, the cam profile is executed cyclically.

  • This means that, when the axis attached to this cam runs continuously, the same profile is executed again.
    • In this case, the first and last element must have the same Vel and Accel values.
    • Changing the Vel or Accel value of the first or last elements automatically changes the other elements' value.

  • When Cyclic is first turned on, the Vel/Accel values are automatically copied from the first element to the last element when they do not match.
    A warning dialog opens indicating this change has happened.
    This alert cannot be suppressed until KASClosed Kollmorgen Automation Suite is closed.

There are some combinations of points and lines where Cyclic is automatically turned off.

If this occurs, the Cyclic checkbox label is changed to Cyclic (automatically turned off).

These changes to the profile automatically turn off Cyclic:

  • The first element has been changed from a point to a line.
    • If needed, Cyclic can be manually turned back on.
      This will affect the velocity of the last element.
  • The next to last element has been changed from a point to a line and now both first and next to last elements are lines.
  • The first element is a line and the first element is moved.
    • If needed, Cyclic can be manually turned back on.
      This will affect the velocity of the last element.
  • The first element is a line and the second element is moved.
    • If needed, Cyclic can be manually turned back on.
      This will affect the velocity of the last element.
  • The first element is a line and the last elements velocity (or slope line) has changed.
    • If needed, Cyclic can be manually turned back on.
      This will change the velocity setting just made.
