Transition from Active Short Circuit to PWM Operation

What is the control method of an inverter to transition from Active short circuit mode to PWM operation mode while the motor is spinning at high speed without causing an overvoltage on the DC link?

Do you have a model number for the inverter? Without it, we can only make wild guesses.
If there is an active short circuit across the motor, it won't spin for very long!

Hi Keith. I am just looking from a control design point of view irrespective of a model.
