To restrain a device from becoming large-sized when drive capability such as a motor and a power converter increases due to a uniform increase in rated speed of an elevator regardless of its in-car load.SOLUTION: A speed pattern forming section 303 forms, when a lifting direction destination command signal is generated, a provisional speed traveling pattern for traveling at a second rated speed of faster, and forms a provisional speed command signal composing the provisional speed traveling pattern. Further, when a light-load estimating signal is generated from a rated load determining section 240, the speed forming section shifts from the provisional speed traveling pattern, forms a maximum speed traveling pattern for traveling at a maximum speed exceeding the second rated speed according to a torque current detecting signal from a torque current detecting section 230, and generates a maximum speed command signal composing the maxim speed traveling pattern.SELECTED DRAWING: Figure 3

    【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、電力変換器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】速度パターン生成部303は、上昇方向行先指令信号が発生すると、第2の定格速度以上により走行する暫定速度走行パターンを生成し、この暫定速度走行パターンを成す暫定速度指令信号を発生すると共に、定格負荷判断部240から軽負荷推定信号が発生すると、暫定速度走行パターンから移行して、トルク電流検出部230からのトルク電流検出信号に基づいて第2の定格速度を越えて最高速度により走行する最高速度走行パターンを生成し、この最高速度走行パターンを成す最高速度指令信号を発生する。【選択図】図3
