Summary:A motor control device (1) for controlling a motor (21) that moves a conveyance part of a crane (2) is provided with: a command generation unit (11) which generates a speed command for the motor (21) on the basis of acceleration/deceleration characteristics of the conveyance part; a notch filter (12) which removes a vibration frequency component of a load from the speed command; a parameter setting unit (16) which sets, for the notch filter (12), a notch parameter (42) designating filter characteristics; and a correction information calculation unit (17) which, on the basis of the notch parameter (42) and a deceleration parameter included in a speed command parameter (41) designating acceleration/deceleration characteristics in a case where the notch filter (12) is not applied, calculates and outputs a movement distance and/or movement time between when the conveyance part starts deceleration and when the conveyance part stops in a case where the notch filter (12) is applied and the motor (21) is driven. 对使起重
