Trip-zone in epwm1 2 3 modules

Hi I want to activate trip zone units in epwm1, 2, 3 modules. When I input the numerical values explained in simulink into the TZSEL input, I cannot obtain the desired low state. I have tried both one-shot and cbc, but I cannot get the results I want. Is there a setting I missed? Are there any places I need to change in the model settings? Can you help me?
