Hi, how do I adjust the FPGA prescaler for the variable PWM block?

Could you elaborate on the question? I might be able to provide additional guidance if you can tell me what you are trying to achieve.

There is no direct access to any pre-scaler or internal FPGA settings for the RT Box, but the frequency output can be manipulated through the f' input into the PWM Out (Variable) component.

Hi Bryan Lieblcik

Please find the conditions from the screenshot below: We use 4e-6sec as the simulation step. 

Basically, I want to maintain the switching frequency at 10kHz and sampling frequency at 250kHz without disabling the PWM synchronization with model steps.

Thank you,

Battur
