To suppress increase in size of a device due to increase in driving capability of a motor, a power converter, and the like when a rated speed of an elevator is uniformly increased regardless of the load inside a car.SOLUTION: In a winding drum type elevator for driving a winding drum by rotating a motor 11 by a power converter 500, a control device 100 includes a speed switching determination unit 220 generating a speed switching OFF signal when a rising OFF signal or a load OFF signal is input and generating a speed switching ON signal when a rising ON signal and a load ON signal are input. A speed pattern generation unit 303 creates a first speed traveling pattern for traveling a car at a rated speed based on the speed switching OFF signal, generates a first speed command signal forming the first speed traveling pattern, creates a second speed traveling pattern for traveling the car faster than the rated speed by the speed switching ON signal, and generates a second speed command signal forming the second speed traveling pattern.SELECTED DRAWING: Figure 2

    【課題】かご内負荷にかかわらずエレベータの定格速度を一律に速くすると、モータ、電力変換装置などの駆動能力が増加して、装置が大型化することを抑制する。【解決手段】電力変換装置500によりモータ11を回転して巻胴を駆動する巻胴式エレベータにおいて、制御装置100は、上昇オフ信号又は荷重オフ信号が入力されると、速度切換えオフ信号を発生すると共に、上昇オン信号及び荷重オン信号が入力されると、速度切換えオン信号を発生する速度切換え判断部220を備え、速度パターン生成部303は、速度切換えオフ信号に基づいてかごを定格速度により走行する第1の速度走行パターンを生成し、第1の速度走行パターンを成す第1の速度指令信号を発生し、速度切換えオン信号により定格速度よりも速くかごを走行する第2の速度走行パターンを生成し、この第2の速度走行パターンを成す第2の速度指令信号を発生する、ものである。【選択図】図2
