Abstract
Stepper motor in the digital control system has a wide range of applications, the traditional stepper motor control circuits of the multi-use interface chip microcontroller or exclusive. However, such control methods SCM vulnerable to electrical interference, flexibility in the use of special interface chip poor shortcomings. This paper presents a CPLD on the stepper motor control, on the stepper motor control hardware circuits and control module, using VHDL language stepper motor speed control, and positive and shows, and other parts of the design and MAXPLUS2 To achieve the ideal simulation. The control CPLD as a core device used to reduce the use of discrete components, in real-time performance and flexibility, and so on have greatly improved. At the same time, VHDL language can be used in accordance with the different stepper motor, the change process parameters can be achieved different models stepper motor control and is conducive to the broad application of stepper motor
