This feature is mandatory in applications that require the
motor to operate in the flux-weakening region. In these
conditions, the back-EMF generated by the rotor spinning is
greater than the bus voltage and the brake feature prevents
the motor from acting as a generator destructively charging
the bus capacitance.
