    摘要: The invention relates to a method and an apparatus. In the method there is determined a speed limit or an acceleration limit for an elevator car based on elevator state information, the elevator state information comprising at least information on whether the elevator car is being driven or whether the elevator car is in a floor. Power supply to the motor is disabled and brakes are applying for braking movement of the elevator car. Speed or acceleration of the elevator car is measured, in response to the applying of the at least one brake and the disabling of the power supply to the motor. It is determined whether the at least one of speed and acceleration of the elevator car exceeds the respective at least one of the speed limit and the acceleration limit. Thereupon, power supply to the motor is enabled for stabilizing movement of the elevator car.
