I've encountered two articles, one here and one by TI, saying slow (current) decay mode (circulating currents in the top or bottom of the bridge) stops motors faster than fast (current) decay mode (using the bridge diodes or transistors to connect the supply voltage so it opposes the established current). A motor will stop faster if the current (torque) is reversed more quickly. By definition, a fast decay mode reduces the current (torque) faster than a slow decay mode. How is it possible that a motor would stop faster when the current (torque) driving the rotation in the direction of the inertia is higher?
Am I missing something?
