Patent ID: 10935956

Abstract:
A positioning control device mounted on an industrial machine including a driver including a motor, a movable body movable by the driver, a first detector that detects a position of the movable body based on the amount of driving of the driver, a servo amplifier that performs first feedback control of feedback-controlling driving of the motor based on a first detection value by the first detector, and a second detector that detects a position of the movable body when the movable body comes closer to a target position within a distance or shorter. The positioning control device is configured to position the movable body at the target position and includes a controller that controls the servo amplifier. The controller includes a switching unit that switches control modes between a first control mode performing the first feedback control and a second control mode disabling the first feedback control of the servo amplifier and performing second feedback control of feedback-controlling driving of the motor based on a second detection value by the second detector.
