【正文】 g to prearrange, the expectation active status movement, must control to its actuation power source, the user needs to develop once more. In view of this, has designed a step of machine universal controller which realizes based on the MSP430F149 monolithic integrated circuit, may satisfy the majority controllingfield originally request. The controller main function is: 外文資料原文 (1) May control the multi wraps step of machine actuation system。 At present may simultaneously control 3 sets of systems. (2) work way is flexible, may according to the hypothesis curve movement, the curve most reach 8 sections。 Definitely may realize this system all signals input, the output, does not need the hardware to expand, P1, the P2 eight bit parallel ports each mouth line all has the severance function, softly causes the keyboard, the hardware design to change is extremely simple. (2) 12 A/D switch ADC。 MSP430F149 provides the rich resources, the periphery hardware expands only must do the 外文資料原文 very few work, not only designs changes extremely imply, and moreover this controller volume small, the reliability is high. steps of machine starting and add/decelerate the control plan The step of motive highest starting frequency (step frequency) generally is arrives 34KHz, but the highest movement frequency may achieve N*102 KHz. Surpasses the highest starting frequency the frequency directon starting, will appear\ Falls out of step \ Phenomenon, even is unable to start. The more ideal starting curve should be according to the index rule starting. But the practical application to starts the section processing to be possible to use according to the fitting a straight Line method, namely \ Steps and ladders law \”. May according to two kind of situations processing, (1) known frequency press t
