【摘要】 目前大多数运动控制卡只能使用专用的上位机控制软件和控制固定的运动轴数,存在轴数控制范围少,难以进行二次开发和扩展的问题。基于对新型运动控制卡PMAC 2A-PC/104的分析,从运动控制卡的硬件结构及上位机的控制软件两个方面入手,解决了运动控制轴数不能变化的问题。方法是:在运动控制卡上调整硬件和添加扩展硬件;用现有的Visual Basic语言把上位机控制软件编制成为一个既易操作又可扩展的友好界面。通过在运动控制卡上作硬件调整和添加扩展硬件,并结合上位机的相关参数设置,就可方便地实现变轴控制。更多还原

【Abstract】 Today’s most movement control cards need special control software of topper computers, and are only suitable for fixed-axis controls. So the number of the axes which can be controlled are limited. Based on the analysis of the new-type movement control card PMAC 2A-PC/104, two aspects relevant to the hardware structure of movement control card and the interrelated software of the topper computers were described. Then two ways to solve the problems were given. The first way was to adjust and expand its hardware on the movement control cards. The second way was to program applied software with existing Visual Basic programming language, and this program was much easier to be operated and expanded by its users. So through adjusting and expanding the hardware of the movement control cards, and through changing parts of the parameters in control software of topper computers, the users can choose different axes which can be controlled, and it is easy to realize multi-axis control.更多还原
