Some VFD's require external braking resistors for fast stops, the one on my mill apparently does, as it won't decel the motor at all if it's spinning fast. ANY 3 phase motor is reversable by simply reversing the 2 of the 3 leads, but that's done by the VFD if you're driving the motor with one.

The extra FET (IGBT) on a dynamic braking-enabled VFD is internal to the VFD, and you have to explicitly enable the feature on the VFD menu (at least, on all 4 of mine, all different vendors). That leads me to believe that the dynamic braking FET is triggered by the STOP or E-STOP function, instead of waiting for a bus overvoltage condition.

The critical role of Dynamic Braking Resistors During the braking process of the motor, the operational mode changes from motoring (power flow from VFD to motor) to re-generating (from motor to VFD). While in the regenerative mode, the energy fed back tends to increase the DC bus voltage of the VFD.
