An apparatus for controlling an emergency stop of an elevator car 11 is connected in an elevator system 10 including a drive motor 15 coupled to the car, a drive control 18 connected between the drive motor and an AC electrical power source 17 for operating the drive motor and an elevator control 19 connected to the drive control for controlling starting, running and stopping of the elevator car. A controlled emergency stop circuit 21 has a battery supply 28 connected to receive and store electrical power from the power source 17 and is connected to provide electrical power to the elevator control 19. A normally open switch 33,34,36,37 is connected between the battery supply 28 and the drive control 18. A controller is connected to the switch and receives a power failure signal representing a loss of electrical power at the drive control 18. The controller responds to the power failure signal by closing the switch to connect the battery supply 28 to the drive control 18 to supply electrical power to the drive means and the elevator control 19 which controls an emergency stop of the elevator car 11 at a predetermined deceleration rate.
