Title:
モータ制御装置およびモータ制御装置の制御方法
Document Type and Number:
Japanese Patent JP6698732
Kind Code:
B2
Abstract:
A motor control device for controlling a servomotor to axially move a movement target object includes: a speed detector for detecting the movement speed of the movement target object; an abnormality detector for detecting an abnormality of the speed detector; a motor controller for performing deceleration control on the servomotor to decelerate the movement target object, upon detection of the abnormality; a reference speed generator for generating a reference speed that decreases with passage of time, based on the movement speed when the movement target object decelerates and a predetermined deceleration; a speed monitor for monitoring the movement speed and determining whether or not the movement speed is equal to or greater than the reference speed; and a brake controller for actuating a brake for braking axial movement of the movement target object when the movement speed is determined to be equal to or greater than the reference speed.
