Y–axis Scales

•A Y-Scale for each input – from left to right, Y1 to Y4 (Y1 is the top input-connector to the Graph FB).

•The color of the Y–axis scale is the same as the graph-line. You can edit the colors with the Graph Setting dialog.

•The default setting is to auto-scale the Y-axis. You can specify a minimum and maximum with the Graph Setting dialog.

Y–axis Data-Channel (Drop-Down list): See also Y–axis Data-Channel Display Options

•Each wire that you connect to an input-connector has 3 Data-Channels.

•You can select the Data-Channel with the drop-down.

Digital Readout (D.R.O.):

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

•The Number-Format for the X–axis, Y–axis, is configured in Application Settings | Number Format tab.

Graph Area:

•The graphs for each wire you connect to a Y-axis input-connector

Toolbar:

•Save, Print, Graph Settings, Zoom Extents, Pan Left, Pan Right, 'Copy Graph Data to Clipboard' – see below

Vertical-Cursor:

When you click or drag your pointer in the graph-area:

•the Vertical-Cursor will move with your pointer

•the Digital-Readouts will continuously equal the Y-axis values at the position of the Vertical-Cursor on the X–axis

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

•the kinematically-defined Chains will move to agree with the Master Machine Angle.

Graph Data in Clipboard

•When you click the right-most tool/icon in the toolbar above the Graphs, the graph data is copied to a list and to your clipboard.

•There is one data-point, for each Machine Step - see Machine-Settings dialog > Number-of-Steps.

Paste this Data to Excel, or to MotionDesigner Data-Transfer table, where you can plot it as a Motion-Overlay.

Why are the Y–axis values given by the D.R.O. slightly different to values for vectors I can see in the graphic-area?

The values may be slightly different because, in the graph, the X–axis and Y–axis values at the D.R.O. must jump from 'machine -step' to 'machine-step', with each machine-step-increment a function of the Machine Settings dialog-box > Number-of-Steps.

In the graphic-area, the vector values are calculated for the value of the Master Machine Angle, which may not coincide with a machine step.

The Y-Axis Data-Channels for each Y-axis Input are in the drop-down boxes, to the right of the graph plots.

You can plot up to three data-channels available at each output-connector of one Function-Blocks

To show up to three data-channels from one output-connector of one Function-Block, drag three wire from the same output-connector to three different input-connectors of the Graph FB.

Kinematic-Function-Block (Linear-Motion, Gearing, Motion, Motion-Dimension) you can plot:

•Linear or angular position

•Linear or angular velocity

•Linear or angular acceleration

Measurement FB or Point-Data FB you can plot

•Linear or angular position

•Linear or angular velocity

•Linear or angular acceleration

Cam-Data FB

•Pressure Angle.
You can plot three Pressure Angles – See Pressure Angle

•Cam Radius-of-Curvature.
You can plot two Radii-of-Curvature: Cam 1 and Cam 2.

•Contact Cam Force

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

Force-Data FB

The output form a Force-Data FB is a function of the element with which it is linked. See Force-Data FB dialog-box

If you link a Force-Data FB to a:

ŸPin-Joint with a Motor, you can plot Motor Load.

ŸSlide-Joint with a Motor, you can plot Motor Load

ŸJoint that does not have a Motor, you can plot:

oTotal Force ( FT = √(FX2 + FY2)

oForce along the X-coordinate of a Point: FX

oForce along the Y-coordinate of a Point: FY

Ÿ2D-Cam: you can plot the Cam Contact Force

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