Creating motion axes with "Constrain"

In the procedure described below, the constraint of the movable part is set with the "Constrain" function and thus the parameter is created.

Creating motion axes with "Constrain" 1:

For the simulation, it does not matter which units are set in the assemblies. The motion axis and displacement sensor units are set in TwinCAT.

The part must be able to be rotated or displaced in the desired direction of movement.
1. Click the Constrain function.

2. Create a parameter by selecting one of the following constraint types:
Mate for translatory motion – with Mate and Flush modes
Angle for rotational motion – with Directed Angle, Undirected Angle, and Explicit Reference Vector modes.
Creating motion axes with "Constrain" 3:
3. In this example, select Flush.
4. Select the reference edge or plane on the part to be moved (purple).

5. Select the reference edge or plane on the part that the part (blue) will move in relation to.
Creating motion axes with "Constrain" 5:
After placing the constraint, the parameter is added to the constrained parts in the model tree as a constraint.
A parameter representing the constraint is appended to the parameter list.
6. Rename the parameter by double-clicking the name so that you can find it more easily for linking.
A parameter representing the constraint is appended to the parameter list.

7. If necessary, configure the TwinCAT 3 Interface for Inventor® before initializing the runtime.
8. Initialize the runtime from Autodesk® Inventor® or use the ScanIO function in your TwinCAT project.
9. Link the I/O master inputs to the relevant inputs in the PLC project. Link the individual I/O master outputs with an output of an NC axis or a suitable output in the PLC project.
See chapter I/O master set up in TwinCAT.
10. Activate the TwinCAT project.
The query asking whether the TwinCAT system should be started in Run Mode appears.
11. Confirm with OK.
The simulation is activated, but is in the pause state.
12. To trigger the runtime, click the Continue button in the TE1130 Inventor® add-in.
The simulation is active and the TwinCAT project is triggered by the Usermode Runtime.
