    摘要： An elevator car and a counterweight is suspended on a sheave by means of a rope in a well-rope faashion. In dependence on the number of passengers on the car, the sheave is applied with an unbalance torque making appearance between the car and counterweight. Upon starting of the elevator operation by releasing a brake, upward or backward bouncing of the car takes place due to the unbalance torque. For preventing such bouncing of the car, a start compensation is performed by generating a motor torque which can cancel out the unbalance torque in precedence to the releasing of the brake. The brake is installed swingably on a winding equipment. Displacement of the brake during actuation thereof indicates the presence of the unbalance torque. By taking advantage of this displacement, the start compensation is carried out by increasing the motor torque progressively in the direction depending on the displacement and by holding the motor torque constant at a value attained when the displacement becomes smaller than a predetermined value.

    摘要： Elevator starting compensation for preventing bounding and dash-out phenomena of an elevator cage possibly occurring due to unbalanced torque produced by a difference in weight between the cage and a counter weight. Adjusting quantities utilized in the starting compensation are arithmetically determined by a microcomputer employed for the elevator control, the result of the arithmetic operation being are stored in an electrically erasable programmable read-only memory. The starting compensation is performed on the basis of the adjusting quantities stored in the memory. The adjustment is facilitated.

    摘要： An elevator control system which is installed in a pit of an elevator shaft in an elevator system is protected from flooding in the pit with the provision of an immersion proof structure for the control system. The elevator control system has a control device which can be installed in the pit of the elevator shaft so as to enhance the maintainability thereof since the necessity of a machine room can be eliminated from the elevator system. The immersion proof structure has a bag-like member which covers the control device and which has a top part opened for heat radiation from the elevator control device, the top part being located above the level of the floor of a lowermost one of stories of a building in which the elevator system is installed.
