hi expert

When i turn off epwm,i used the following code,

EPWM_forceTripZoneEvent(obj->pwmHandle[0], EPWM_TZ_FORCE_EVENT_OST);
EPWM_forceTripZoneEvent(obj->pwmHandle[1], EPWM_TZ_FORCE_EVENT_OST);
EPWM_forceTripZoneEvent(obj->pwmHandle[2], EPWM_TZ_FORCE_EVENT_OST);

Is there any other way to turn off PWM？suah as outmask?

Hi Youjun,

This is one of the most common ways to turn off the PWM by the trip zone submodule. To turn off the PWM there are two common ways. Using turning off the outputs via the action qualifier or trip zone configurations.

If PWM complementary output is used，how to used the action qualifier to turn off the pwm?

Hi Youjun,

If you're using PWM complementary where the dead band is sourced by either 1A or 1B and inverting one of the outputs then the trip zone has to be used.
