Active Motion Settings

Edit Toolbar : Active Motion Settings

To open the Active Motion Settings dialog-box

1.Click Edit toolbar > Active Motion Settings.
Active Motion Settings dialog-box

Active Motion Settings dialog-box

There are four tabs in the Active Motion Settings dialog-box.

Dialog Separators

The Dialog Separators are Horizontal Orange Bars.

Click the orange separator to show the contextual parameters.

For example, the separators in the image to the left are:

Motion Name
Motion Cycle Data
Motion Units

The two buttons at the bottom of the Active Motion Settings dialog-box are:

'Save as Defaults': ['Defs' is 'Defaults'].

Use this button to make the changes become the new Active Motion Settings.

'Load Defaults':

Use this button to load new, saved, Active Motion Settings.

Note: The Active Motion Settings become the default settings when you save a model and then exit MechDesigner.



Motion Name

Motion Name [Read / Write]

1.Enter a new name with your keyboard.
2.Press the Enter [also called 'Return'] key on your keyboard.


Motion Cycle Data

Number-of-Steps [Read / Write]

The number of points along each motion graph.

Note: MotionDesigner evaluates motion-values at all and ANY value of the X–axis.

Cycles / Min: [Read Only]

See MechDesigner >Edit menu > Machine Settings]

Seconds / Cycle [Read Only]

Seconds / Cycle = 1÷ Cycles/Min

IMPORTANT: 'Cycle/Minute' [MechDesigner] and 'Motion-Width' [MotionDesigner]

To make sure the duration of the motion is correct in MotionDesigner, you must edit the machine-speed in MechDesigner. See MechDesigner > Edit menu > Machine Settings so that Seconds/Cycle is = the Motion Width.

For example: If you want a cycle time of 1200ms (milliseconds), then enter (60*1000)/1200 = 50 Cycles/Minute.

Then, if you change the X–axis units to msecs, one cycle will equal 1200msecs, and not 1000msecs.


Position Units: Units
Y Velocity Units: Units/sec
Y Acceleration Units: Units/sec/sec
Y Jerk Units: Units/sec/sec/sec

Note: The scale of the model does not change when you edit 'Units'.

For example: 90mm becomes 0.090m or 3.543inches.
