Abstract

PURPOSE: To accurately perform adjustment for a rope elongation detector or a releveling device with an easy operation by computing the adjusting factor of a second position detector by a microcomputer and storing this in a nonvolatile memory. CONSTITUTION: An elevator car 1 and a balance weight 2 are connected to each other by a rope 4, and arranged in a well bucket shape by a hoist 3. A controller 7 controls the speed of an induction motor 8 according to its rotation, in other words, the output of a pulse generator 9 for generating a specified pulse according to the speed and position of an elevator, and returns position and speed signals to the controller 7, and then the speed of the induction motor 8 is controlled. Second position detectors POSi1 and POSi2 are provided on the car 1, and generate specified output signals by shutting off with a shutting plate 5 in a hoistway. By this output characteristic, the level error of the car 1 or the elongation/contraction of the rope 4 following a change in load in the car is detected.
