中国经济持续快速的增长,为线缆产品提供了巨大的市场空间,中国市场强烈的诱惑力,使得世界都把目光聚焦于中国市场,在改革开放短短的几十年,中国线缆制造业所形成的庞大生产能力让世界刮目相看。随着中国电力工业、数据通信业、汽车业以及造船等行业规模的不断扩大,对电线电缆的需求也将迅速增长,未来电线电缆业还有巨大的发展潜力。
plc是现代工业的基础,虽然它是第二次工业革命的产物,但是经历了近一个世纪的风风雨雨,它不但没有消失,而且越来越强大,不但工业生产广泛使用,在生活中也应用广泛。很多在工厂从事维修保养的电工朋友,以及刚从学校毕业的学生想从事自动化行业,PLC是绕不开的坎。可苦于没有相关经验,更没有前辈带路,再加上现在大师专家满天飞,导致走了很多弯路,为此小编特意整理希望能给大家带来帮助。纠结品牌这是常见,也是LOW的问题了,经常在后台留言上有人如此提问,入门是学习三菱plc还是西门子plc好?我有三菱的基础了,多久能学会西门子PLC?对于此等入门的低级问题,不想再重复,等你纠结好了,估计黄花菜都腐烂了。

为了省钱有时还得用步进驱动来控制,两个不同型号驱动器对同一型号的步进电机的设置。步进电机的型号:原来老机器上配的步进驱动器型号:2HB808MAE新造几台机器老型号驱动器订不到了,电机还能订到。新的驱动器型号:MA860H这一看和我原先的不一样。我开始旋转大脑,从网上查资料得知对于电机的步距角是1.8度,也就是转一圈要200个脉冲。而老的型号设的是1,3,4,6,7,9为ON我对照了一下老的是设为:也就是9*200=1800个脉冲转一圏。
