<p>Provided is a control system for an elevator, capable of performing speed control while balancing rope tension applied to two hoists. The control system for an elevator two hoisting machines; two ropes looped around the two hoisting machines respectively; a car engaged with each of the two ropes at one end thereof; counterweights engaged with each of the two ropes at the other end thereof; a drive control device for driving the two hoisting machines; tension detectors for detecting respective rope tensions of the two ropes; and a compensator for outputting a feedback control signal to the drive control device in accordance with a difference between the tensions of the two ropes detected by the tension detectors to control rotational speeds of the hoisting machines with a view to balancing the rope tensions with each other.</p> |
