Circuit breakers in" Specialized power systems" cause PMSM motor graphs to stop display

Hello,

I am trying to simulate a PMSM with a speed control.

when I intreduced a circuit breaker before the motor, once the breaker is activated, the displays of the motor parameters (e.g., speed) stops.

I tried also with Ideal switch but it doesnt work.

Does anyone have an idea how to solve it?

Thank you very much!

The parameter file is missing; therefore, it is not possible to simulate and reproduce the problem. It is possible to use a breaker to disconnect the PMSM. The issue may be related to the parameterization of components, especially the breaker, which could be causing difficulties.

Please note that Speed Controller (AC), DC Bus, and other blocks have been removed in R2024b:

I do not understand what you mean by the phrase "The parameter file." ?? It looks as if some words got skipped ?

I am also unclear what is meant by "it may be parameterization" ?

@Walter Roberson, Thank you for pointing this out; there were indeed some words missing. I have now updated the text.
