The system includes ADLINK motion control card PCI-8134, LEETRO stepper motor drivers DMD 402A, and tables with LEETRO DM4240A stepper motors. The system uses ADLINK PCI-8134 to send stepping pulse signal PUL and direction level signal DIR to control the stepper motor’s rotation angle and direction, achieving the motor’ positive and negative rotation, acceleration, constant speed and deceleration, then achieving the radial motion of table’s Z-axis slider along the surface of the measured part, the axial motion of X-axis slider along the surface of the measured part and the spindle rotation for the measurement of roundness and cylindricity. ? 2011 Published by Elsevier Ltd.

Because of its simple structure, reliability, well controlled, anti-interference ability, no accumulated error and direct digital control, the stepper motor is widely used in automatic control systems. In the design of stepper motor control system, the traditional method is to use logic circuits or single chip to control stepper motor, conditioning the input analog signals and converting the signals into digital signals by the A / D, then a microprocessor in accordance with the function requirement does necessary analysis and processing on the collected data, and then the processed data is stored and displayed or output the analog signals converted by
