see Add Motion FB
A Motion FB is a direct a link to a Motion, which is identified by its Motion name-tab in MotionDesigner.
After you edit a Motion FB to select a Motion:
•The motion-data at the input-connector to the Motion FB control the X-axis of the Motion
•The motion-data at the output-connector from the Motion FB correspond to the Y-axis of the Motion
Note: The Motion FB selects the left-most Motion name-tab as the default motion.
To open the Motion FB dialog
The Motion FB dialog is now open.
Motion FB dialog
After each Motion Cycle:
* You must select Linear or Rotary if you connect a wire from a Motion FB to a Motion-Path or a Math FB.
Ignore this separator
Enter a Y-axis value
This is best explained with an example model:
1.Design an Indexing Motion in MotionDesigner with two Segments:
Segment 1: Index (X-axis: 0-240; Y-axis: 0-90)
Segment 2: Dwell (X-axis: 240-360, Y-axis: 90).
2.Connect a Linear-Motion FB to a Gearing FB. Connect the Gearing FB to a Motion FB. Connect the Motion FB to a Motion-Dimension FB which controls an rotating Motion-Part.
3.Edit the Motion FB.
Select the Indexing Motion you have designed.
Select Reset as the After each motion-cycle parameter
4.Edit the Gearing FB.
Edit the Gearing Ratio. Enter 4
As the MMA increases from 0 to 360, the output from the Gearing FB increases from 0 to 1440 ( Gearing Ratio × 360 )
As the MMA increases from 0 to 360, the output from the Motion FB increases from 0 to 90, and jumps to 0 again each time the input is an integer multiple of 360.
The indexing-shaft resets its position 4 times.
Now, select Accumulate Output as the after each Motion Cycle parameter
The indexing-shaft indexs 4 times, to make one complete revolution, as the input increases from 0 to 1440.
