For the purpose of composing a precise positioning control conveying manipulator,the positioning control design of using PLC’s high speed pulse train output to control servo drive is proposed,with the example of S7 200 series PLC and Panasonic servo drive.%为了建成一套精确定位的输送机械手控制系统,以西门子S7200系列PLC和松下 MI-NASA5系列交流伺服驱动器为例,提出了使用PLC主机单元的高速脉冲输出端口控制伺服驱动器实现定位控制的方案。
