If the unit is provided with Reverse power / Anti-motoring protection, it will operate.
When the machine is accidentally energised, the Excitation is OFF. So, Field failure protection is another one that could operate.
The new machines often are provided Protection against Accidental energisation. If the subject unit has this, then this will be the fastest one to operate.
