An emergency stop in a forward-reverse motor control circuit is a safety device that cuts the control power, removing drive signals from both direction contactors. When pressed, it de-energizes both contactors, so neither forward nor reverse is energized and the motor stops, even if it was running in one direction or coasting. This guarantees a quick, safe stop in all situations. It may be accompanied by braking if the system has a brake, but the core action is removing control power to stop movement in both directions. The other options describe energizing both directions, automatic reversal, or speeding up, which do not reflect how an emergency stop functions.
