Motion-Dimension FB

see Add Motion-Dimension FB


Motion-Dimension FB

A Motion-Dimension FB

identifies a Part [Motion-Part] you want to move with motion-values.
specifies its starting-position
specifies its positive direction for increasing motion-values

When the Motion-Dimension FB specifies the:

Angular Position of Part, it is a Rocker

Icon-FB-MotDim-Rocker

<< the Motion-Dimension FB in the graphic-area

When the Motion-Dimension FB specifies the:

Linear Position of a Part, it is a Slider

Icon-FB-MotDim-Slider

<< the Motion-Dimension FB in the graphic-area


Edit the Motion-Dimension FB

Edit the Motion-Dimension FB:

1.Double-click the Motion-Dimension FB in the graphic-area or Assembly-Tree

- or -

The Motion-Dimension dialog-box is now open.

Motion-Dimension FB dialog-box

The Motion-Dimension FB function is:

Output  = Input + Base-Value

Dialog-13.2-Motion-DimensionFB

1s-red Base-Value:

The 'constant' contribution to the Motion-Dimension

2s Motion-Value: (read-only)

The 'motion' contribution to the Motion-Dimension at the input-connector to the Motion-Dimension FB.

2s Base-Value + Motion-Value

∑ Base-Value + Motion-Value = Motion-Dimension

∑ 74 + 91.559104 = 84.159921


Note: Units are determined by the data-type at the input-connector


 Directions 


Note: I generally do not use  Directions  - I prefer to arrange the model so that I can predict the positive directions.


5s Negate Motion-Values:

Positive Motion-Values : Motion-Value × 1 [default]
Negative Motion-Values : Motion-Value × –1

6s Negate Base-Values

Positive Base-Value : Base-Value × 1 [ default ]
Negative Base-Value - Base-Value × –1

Notes:

The Positive direction of a Motion-Dimension:

Rocker - counter-clockwise angle

Slider  - direction of arrowhead on Slide-Joint  - See Positive Direction of Sliders
