TIM1_BKIN Behavior When Fault is Detected

War_Babylon! · ‎2021-06-04

Please I want to Know how TIM1_BKIN for example in STM32F103C8T6, behavior when it detects fault and when the Fault disappears? What is the approximate Time it may take to turn off the TIM1 PWMs Channels ant when the fault disappears, does it delay to turn the TIM1 Back on?

The effect of Break coming active is immediate (asynchronous) but what exactly happens next depends on several configuration bits. If AOE is set and Break gets inactive, MOE gets set at the next Update event (usually next timer overflow).

Read the Using the break function subchapter of TIM chapter in RM.

Thanks @Community member for the answer.

+ Read the application note AN4277 Using STM32 device PWM shut-down features for motor control and digital power conversion.

@War_Babylon! : it will explain more the break feature based on some examples.
