Powerstage Protection of RTBox in Simulation

General

Hi,

I wanted to test my Powerstage Protection linked to a PWM output of RTBox1 in Simulation. But it didn’t work as expected.

So a made a simple example in the attachement.

I have the system separated into a Controller and a Plant. The Controller and Plant are set to code generation and to normal simulation mode.

Simulation start:

  • Enable Input = 0
  • Trip Input = 1
    ——————————-
  • Power Stage Output = 0
  • BUT: PWM is already running

after 5ms

  • Enable Input = 0
  • set Trip Input = 0
    ——————————-
  • Power Stage Output = 0
  • BUT: PWM is still running

after 10ms

  • set Enable Input = 1
  • Trip Input = 0
    ——————————-
  • Power Stage Output = 0
  • BUT: PWM is still running –> I would expect that the PWM output would start only now after a rising edge on the Enable Input

But the PWM Capture in the Plant sees the PWM starting at Simulation start immediately.

I tried also switching from HIL to RCP and back.

Is there something I messed up in wiring / parameter settings? Can someone help me please?
