Configuring the SCIM Model
In this example, the SCIM model has been pre-configured. For more information about machine configuration, please refer to the SCIM Section. Explore the machine configuration described below.
- In the Configuration Tree, expand Circuit Model >> Machines and click SCIM 1 to open the configuration page for the machine.
- Observe the configured machine parameters. The Input Mapping subsection allows the outputs of the circuit model to be easily connected to the inputs of the machine.
- In the Configuration tree, expand SCIM 1 and click Mechanical Model to view the mechanical model parameters.
- Confirm that the parameter values match those in the table below.
