Abstract

The subject of the invention is to easily adjust a velocity mode of a stepping motor when the stepping motor drives driven parts such as a sewing machine and the like to prevent maladjustment, vibration and the like. When drive is tested, the drive pulse number which is provided to the stepping motor and time series data of a practical rotation angle of the motor at present are collected and then a picture display is made out in a chart mode. The output time of each drive pulse is also displayed together, which can be changed.

Description

(1) Technical field [0001] The present invention relates to a stepping motor control device, and more particularly, to a control device capable of easily adjusting the reference speed pattern when the stepping motor is rotated by a predetermined amount or moved linearly according to a predetermined speed pattern, and a sewing machine using the same . (2) Background technology [0002] A stepper motor can also be called a pulse motor, which is a motor that rotates or moves linearly at an angle proportional to the number of drive pulses output by the control device (hereinafter, the combination of rotation and linear movement is expressed as movement) . Therefore, the control device can control the speed and the moving amount by open-loop control without detecting the actual moving amount of the pulse motor. This open-loop control is simpler than the feedback control that feeds back the actual movement amount to the control device, so most industrial equipment uses a steppin...
