see Add Graph FB
Use a Graph FB to plot Kinematic Motion-Data, Kinetostatic Force-Data and Cam-Data.
4 × Y-axis input: the top four(4) input-connectors are for four different graphs.
1 × X-axis input: the bottom input-connector is the X-axis for all of the graphs. If you do not connect a wire to this input-connector, the X-axis is a machine-cycle, 0 – 360.
Edit the Graph FB:
The Graph interface is now open. |
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 |

Vertical-Cursor
When you click or drag your pointer in the graph-area •the Vertical-Cursor will move with your pointer •the Digital-Readouts •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
To list the graph data-values •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 or as a List segment-type. |
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 increment of the machine-step 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 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-Blocks (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 •Pressure Angle. •Cam Radius-of-Curvature. •Contact Cam Force •Maximum Contact Shear Stress. •Sliding-Velocity. 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: ☑Total Force ( FT = √(FX2 + FY2) ☑Force along the X-coordinate of a Point: FX ☑Force 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. |
