WebSlow decay uses the same FET topology than brake, but they are two different scenarios. On slow decay, both same side FETs are ON and the current decays slowly. The key work here is "current decays". Once current reaches zero, then Brake occurs and this is when you see the BACK EMF taking over and pushing a current opposing to the initial current. WebIf NF is detected in the early period of the fchop cycle, the Slow Decay will be longer. If NF is detected in the late period of the fchop cycle, the Slow Decay will be shorter, as shown above.
