Control of stepper motor based on VC++ and PCI-1240

With the platform of industrial PC and VC++ software, this paper researches on how to use PCI-1240 motor control card to achieve the control of stepper motor by sending control signals to stepper motor controller. A control system to realize the accurate control of the motion of stepper motor is designed. It is proved that this method is accurate, reliable, easy to operate, and practical in industry.
