    May 28, 2009 A good VFD with dynamic braking will do it. But if you want it to take place at the fastest possible speed, i.e. plug reversing with no ramp up or down, the motor will require Locked Rotor Current from the VFD. So you would need to size the VFD based upon the OL capacity being 6X the motor FLA.
