Configuring the RRSM Model

In this example, the RRSM model has been pre-configured. For more information about machine configuration, please refer to the IM SM Section. Explore the machine configuration described below.

In the Configuration Tree, expand Circuit Model >> Machines and click IM SM 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 connected to the inputs of the machine.
In the Configuration tree, expand IM SM 1 and click Mechanical Model to view the mechanical model parameters.
Confirm that the parameter values match those in the table below.
