An elevator system having speed control apparatus providing first, second and third acceleration modes which provide progressively higher maximum speeds for an elevator car. Control circuitry associated with each landing to be served by the elevator car is successively enabled in response to the location and movement of the elevator car, with the number of floors from the last stop of the elevator car to the floor of the next stop being used to select one of the three acceleration modes. Protective apparatus responsive to the voltage across the armature circuit of the elevator drive motor is also provided which stops the elevator car when the rate of change of this voltage exceeds a predetermined magnitude, or the magnitude and polarity of the voltage indicates the elevator car is traveling at or above a predetermined speed in a direction opposite to the travel direction selected by the control circuitry.
