A method for setting a hoist having an encoder for detecting the rotation of a drive motor and rotating a load pulley by the drive of the drive motor to wind up or unwind a load chain to raise or lower goods, the method comprising: a driving step for driving the load chain while applying tension to the load chain, and driving the load chain to rotate the load pulley while applying tension to the load chain; one side drives the driving motor at a fixed rotation speed; a storage step in which a motor torque command value for controlling the drive motor is stored in a storage unit in association with position information obtained from the encoder in the driving step; and a speed correction curve calculation step for calculating a speed correction curve for driving the drive motor on the basis of the periodic variation of the motor torque command value stored in the storage step.

    一种卷扬机的设定方法,该卷扬机具有检测驱动电动机的旋转的编码器,并且,通过驱动电动机的驱动使负载滑轮旋转,由此将负载链卷起或解绕解绕,从而使货物上升或下降,该卷扬机的设定方法包括:驱动步骤,其一边对负载链施加张力,一边以固定的旋转速度驱动驱动电动机;存储步骤,其将用于控制驱动电动机的电动机转矩指令值与驱动步骤中从编码器获得的位置信息相对应地存储于存储单元中;速度校正曲线计算步骤,其根据存储步骤中存储的电动机转矩指令值的周期性变动,计算驱动驱动电动机的速度校正曲线。
