To facilitate lifting and lowering of an article by lifting and lowering it with slight force when the article is balanced in an arbitrary position and is set in a prescribed state.SOLUTION: An electrical angle calculation unit 215 calculates a set electrical angle θ by referring to a noise removal signal of a subtraction signal obtained by subtracting a weight registration value registered in a weight registration unit from a weight signal W including a weight which an operator applies and referring to an input signal transmitted from an operation unit 190. A torque current command value generation unit 212 generates a noise removal weight signal obtained by removing high frequency noise of the weight signal W including the weight which the operator applies, and calculates a torque current command value Iq* by referring to the noise removal weight signal and the input signal transmitted from the operation unit 190. A motor controller 200 controls a motor 120 by vector control by using the set electrical angle θ and the torque current command value Iq*, which are thus calculated, and performs balance control of a lifting and lowering device.SELECTED DRAWING: Figure 5

    【課題】物品を任意の位置でバランスさせたり、所定の状態にしているときに、僅かな力で昇降移動させて、物品の昇降移動を容易にする。【解決手段】電気角算出部215は、作業者が印加した重量を含んだ重量信号Wから重量登録部に登録された重量登録値を差し引いた減算信号のノイズ除去信号、及び、操作部190から送られた入力信号を参照して、設定電気角θを演算する。また、トルク電流指令値生成部212は、作業者が印加した重量を含んだ重量信号Wの高周波ノイズを除去したノイズ除去重量信号を生成し、ノイズ除去重量信号及び操作部190から送られた入力信号を参照して、トルク電流指令値Iq*を演算する。モータ制御装置200は、こうして演算された設定電気角θ及びトルク電流指令値Iq*を用いて、ベクトル制御によりモータ120を制御し、昇降装置のバランス制御を実行する。【選択図】図5
