摘要
通过分析水平驱动剪刀撑升降台的特点及技术要求,提出了变频器PROFIBUS DP现场总线控制系统.控制系统采用S7300PLC作为中央控制器,PⅢ工控机作为监控计算机,SIEMENS6SE70系列变频器作为DP从站,构成了一个基于PROFIBUS DP现场总线的控制网络.该系统可实现台面的匀速运动和准确定位,且接线简单、维护方便、工作可靠.
An on-site bus control system with frequence converter PROFIBUS-DP FIELDBUS was presented on the basis of analyzing the characteristics and technical specifications of horizontally driven elevator with scissors-truss support.The S7300 PLC was used as central controller,PⅢIPC as monitoring machine,and SIEMENS 6SE70 series frequence converter as DP slave station to compose a PROFIBUS-DP FIELDBUS control network.The control system can not only make the elevator move uniformly and be positioned exactly but also make the wiring simple,maintenance convenience,and operation safe.
