Title:
MOTOR DRIVE CONTROL DEVICE, CONTROL METHOD OF THE SAME, CONTROL PROGRAM OF THE SAME, AND METHOD OF DETERMINING DIVISION NUMBER OF BASIC STEP ANGLE
Document Type and Number:
Japanese Patent JP2018148749
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor drive control device capable of taking measures against vibration or noise of a motor.SOLUTION: The motor drive control device for driving a stepping motor in a micro step controls the number of PWM (Pulse Width Modulation) periods included in one micro step period. More specifically, in order to prevent a vibration included in a current waveform determined by the number of PWM periods included in one micro step period to be close to the natural frequency of a stepping motor, the number of PWM periods included in one micro step cycle is controlled.SELECTED DRAWING: Figure 3
