REDUCING SPEED AUTO CORRECTION METHOD FOR DIRECT LANDING OF ELEVATOR

摘要

PURPOSE: An automatic deceleration compensation method of an elevator is provided to automatically concentrate deceleration of an elevator. CONSTITUTION: An automatic deceleration compensation method of an elevator is as follows. The normal deceleration obtains deceleration pattern from a speed and distance graph in a deceleration section. The area at a fixed section of a constant deceleration section of a speed and distance graph is calculated. The calculation is performed based on a speed control cycle of an inverter in order to reduce an error of distance. The elevator is automatically recompensed in order to have a fixed speed and the fixed location.
