Kinematic FB | Add Graph FB

Add Graph FB

MD-Icon-FB-Graphs

Kinematics FB toolbar > Graph FB

Menu :

Add menu > Add Graph FB

STEP 1: Add a Graph FB to the graphic-area

1.Click Add menu > Add Graph FB

- or -

Click Kinematics FB toolbar > Add Graph FB

2.Click the graphic-area

The Graph FB is now in the graphic-area.

STEP 2: Connect wires to the input-connectors of the Graph GB

The Graph FB has five(5) input-connectors.

From the top, the input-connectors are:

•#1 –# 4 : Y-axis inputs - See Below: Y-axis Data-Channel Options

•#5 : X-axis input - See below X-axis Data-Channel Options

Note:  Options for the X-axis (#5 input-connector)

Option 1: no input (not connected): the X-axis will follow the Master-Machine-Angle

Option 2: input increase steadily. e.g. from the output-connector of a Linear-Motion FB, or Gearing FB.

Option 3: input increase and decrease with a range of values. e.g. from the output-connector of a Motion FB, Measurement FB, or Point-Data FB

Note: if there is a fly-back across the graph, click Rebuild Now - this command will often remove the fly-back.

If that fails, increase the number-of-step along the graph to ~360  with Machine-Settings > Number-of-Steps.3

STEP 3: Open the Graph FB

1.Double-click the Graph FB in the graphic-area

- or -

See How to open a Dialog-Box

The Graph dialog-box is now open.

STEP 4: See: Graph FB Interface.

To review the kinematic, kinetostatic and Cam-Data that you can plot with a Graph FB.

Graph FB:

1r Y–axis : Scales

•Maximum 4 scales, that correspond to motion-value at input-connectors Y1 to Y4

•The color of the Y–axis and the plot-line are the same.

2r Y–axis : Digital Readout (D.R.O.)

•The X-axis and the Y1 – Y4-axis values at the position of the vertical cursor Red-14-6.

•The Number-Format for the X–axis, Y–axis, and data in ClipboardRed-14-7 are configured in Application Settings | Number Format tab.

3rData-Channel Selector

•Each wire that is connected to an input-connector has up to 3 Data-Channels

•Select the Data-Channel in the drop-down box - see Y–axis Data-Channel Options

4r The Graph Area:

•The color-coded graphs for each Y–axis input

•Vertical-CursorRed-14-6 - see more below

5r Toolbar:

•Save, Print, Graph Settings, Zoom Extents, Pan Left, Pan Right, Copy Graph Data to Clipboard – see Red-14-7 below

6r Vertical-Cursor

When you click in the area of the GraphRed-14-4, the Vertical CursorRed-14-6 will snap to your mouse pointer

When you drag your pointer in the graph :

•the Vertical-Cursor will follow your pointer

•the Digital ReadoutsRed-14-3 will continuously update to indicate the Y-axis values at the X-axis position of the Vertical-Cursor

•the Master Machine Angle will update to the value of the X-axis position of the Vertical Cursor

•the kinematically-defined Chains will move to value of the Master Machine Angle

7r Copy Graph Data to Clipboard

•When you click the right-most icon in the toolbarRed-14-5, the graph data is copied to the ClipboardRed-14-7.

•Paste this data to Excel, or

•To MotionDesigner in the Data Transfer table. You can plot it as an overlay or use it as a Motion (use Z Raw-Data).

Notes:

•Configure the Number-Format for the X–axis, Y–axis, and 'Data in Clipboard' in Application Settings | Number Format tab.
2r tog_minusY-Axis Data-Channel Options:

Each wire you connect to the Graph FB has three Data-Channels.

Use the Y-axis Selector to select which data-channel to plot.

The data-channels that are available with each wire are a function of the FB from which you connector the wire to the Graph FB input-connector.

If the wire you connect to the Y–axis input-connector is from a:

•Function-Block (Linear-Motion, Gearing, Motion, Motion-Dimension):

oLinear position, velocity, acceleration of the Measurement Dimension or Point.

oAngular position, velocity, acceleration of the Measurement Dimension.

•Measurement FB or Point-Data FB:

oLinear position, velocity, acceleration of the Measurement or Point

oAngular position, velocity, acceleration of the Measurement

•Cam-Data FB

oPressure-Angle.
You can plot three Pressure Angles – See Pressure Angle

oCam Radius-of-Curvature.
You can plot Radii-of-Curvature for Cam 1 and Cam 2.

oContact Cam-Force

oMaximum Contact-Shear-Stress.
You must know the material-properties to obtain this data. See 2D-Cam dialog-box.

•Force-Data FB

If the Force-Data FB references a:

oPin-Joint with a motor, and gearbox  you can plot Motor Drive Torque.

oSlide-Joint with a motor, you can plot Motor Drive Linear Force

oJoint

▪Total Force ( FT = √(FX2 + FY2), or

▪Force in the X-axis direction : FX

▪Force in the Y-axis direction: FY

o2D-Cam: you can plot the Cam Contact Force

oSpring FB: you can plot the Total Force, the X Force and the Y Force acting on the Point.

Note:

To show all three Data-Channels from one output-connector a Function-Block, then drag a wire from the same output-connector to different input-connectors on the Graph FB.
