Abstract: PURPOSE: A vibration reducing device is provided to reduce the vibration generated by the completely closed state of a check valve through slowly decreasing motor current regardless of the opened state of a check valve caused by wrong load compensation. CONSTITUTION: A load compensating operation is performed as a car operation command is generated. After finishing the car compensating operation, an operation mode is set for generating a car speed command value. The errors of car speed and motor speed are calculated for driving a motor with a motor current command value. As a car stop command is generated, a clamp mode is performed for outputting a final torque current value in the load compensating operation. The final torque current value is reduced to a specific value while outputting a torque current value for a specific time. As the torque current value is under zero, the motor is stopped. Even though a check valve is open by wrong load compensation in a settling mode of a car, the vibration generated during the complete closing of the car is reduced by slowly reducing the motor current.
