Each degree-of-freedom in a kinematic-chain has a power-source.

In the default case, the power-source is a motor at the joint whose motion you control with a Motion-Dimension FB. Frequently, the motor is at a different joint, or a Cam provides the power to move a kinematic-chain.

If the power-source for a degree-of-freedom is not the correct element, you must use the Configure Power Source dialog to move it to the correct element.

The elements that can be a power-source are: Pin-Joints, Slide-Joints, 2D-Cams, Springs, and pulleys.

In the default case, the Power-Source is at the joint whose position and motion you control with a Motion-Dimension FB.

A Motor-Symbol represents a Power-Source at the joint.

To see the Motor-Symbol, toggle on:

•Forces toolbar > Force-Vectors: Calculate

•Force toolbar > Force-Vectors: Display

1.Click the Kinematics-Tree in the Element-Explorer

2.Click the Kinematic-Chain for which you want to control the Power-Source.

The Kinematic-Chain should be Blue.

3.Right-click the  Kinematic-Chain  in the Kinematics-Tree

4.Click Configure Power Source in the shortcut menu (see image, left)

OR

3.Press the ALT+P keyboard shortcut

The Configure Power Source dialog is now open.

See Configure Power Source dialog.

In the Kinematics-Tree:

1.Click the Kinematics-Tree in the Element-Explorer

2.Click the Kinematic-Chain

The  Kinematic-Chain  should be Blue.

3.Click Force toolbar (or menu) > Configure Power Source icon.

or
