Abstract

본 발명은 전동기의 정지 시간을 짧게 실현할 수 있는 전동기의 위치 제어 방법에 관한 것으로, 정상적인 전동기(1)의 구동 속도에서 발자체(7) 신호에 따른 엔토더(2)의 출력펄스 수를 측정하여 기억시킨 후 외부의 정위치 정지 명령이 들어오면 준비 속도 시작지점(A)까지 감속하는 단계, 매순간 감속완료 여부를 확인하여 감속완료시 그 감속 완료된 지점(A)에서 직선 감속 시작지점(B)을 예측하여 예측된 지점(B)까지 등속회전하는 단계, 직선 감속 시작지점(B)이 되면 직선 감속하여 발자체(7) 신호가 검출된 발자체(7) 신호를 따라 감속하여 목표지점(C)에서 정지하는 단계로 이루어진다.The present invention relates to a method for controlling the position of a motor that can realize a short stop time of the motor, by measuring the number of output pulses of the encoder 2 according to the signal of the footer 7 at a normal driving speed of the motor 1 When the external exact position stop command comes in after storing, decelerate to the preparation speed start point (A), and check whether the deceleration is completed every moment.When the deceleration is completed, the linear deceleration start point (B) is The step of predicting and rotating at a constant speed to the predicted point (B), and when the linear deceleration start point (B) is reached, decelerates linearly and decelerates according to the footstep (7) signal from which the footstep (7) signal is detected. It is made to stop at.

Claims

After measuring and storing the number of output pulses of the encoder 2 according to the footer 7 signal at the normal driving speed of the motor 1, if an external exact stop command comes in, the motor decelerates to the preparation speed start point A. Step to check whether the deceleration is completed every moment, and when the deceleration is completed, the step of predicting the linear deceleration start point (B) from the deceleration completed point (A) to rotate at constant speed to the predicted point (B), and the linear deceleration start point (B) The motor control method according to claim 1, wherein the motor decelerates linearly and decelerates according to the signal of the footer (7) and stops at the target point (C).
