福州卓凯电子科技有限公司
我公司主要经营西门子，欧姆龙，倍加福，横河川仪，abb,施耐德等国外多家知名品牌，产品涉及变频器，仪器仪表，变送器，可编程控制器plc和人机界面，工控机及气动阀门等。产品广泛应用于全国各地，如：钢铁厂，石油厂，化工厂，水泥厂，啤酒厂，冶金厂，造纸厂，电力，监控，水利水电，机械等各种不同的工业部门系统需要。
● 输入/输出线不能用同一根电缆，输入/输出线要分开。
● 尽可能采用常开触点形式连接到输入端，使编制的梯形图与继电器原理图一致，便于阅读。
输出连接
● 输出端接线分为独立输出和公共输出。在不同组中，可采用不同类型和电压等级的输出电压。但在同一组中的输出只能用同一类型、同一电压等级的电源。 ● 由于PLC的输出元件被封装在印制电路板上，并且连接至端子板，若将连接输出元件的负载短路，将烧毁印制电路板。
● 采用继电器输出时，所承受的电感性负载的大小，会影响到继电器的使用寿命，因此，使用电感性负载时应合理选择，或加隔离继电器。随着我国各地用电量的大幅攀升和配电线路的增加，配网调度的工作量明显增加。
● PLC的输出负载可能产生干扰，因此要采取措施加以控制，如直流输出的续流管保护，交流输出的阻容吸收电路，晶体管及双向晶闸管输出的旁路电阻保护。
四、如何让PCL变频器实现多电机控制通信系统是主站系统与配电网终端设备联接的纽带，主站与终端设备间的信息交互都是通过通信系统完成，因此必须有稳定可靠的通信系统，才能实现配网自动化的功能。
1、在传统的传动系统中，要保证多个执行元件间速度的一定关系，其中包括保证其间的速度同步或具有一定的速比，常采用机械传动刚性联接装置来实现。但有时若多个执行元件间的机械传动装置较大，执行元件间的距离较远时，就只得考虑采用独立控制的非刚性联接传动方法。主不分从，各电动机的轴端均套装码器及各变频器中加装测速反馈选件卡FR—A5AP，并将编码器输出端与测速反馈选件卡输入端相连，使每台电动机和编码器各自构成闭环装置，可按照它们不同的速度增益比例同时给予变频器主速设定，产同时起动和停止。虽然在系统中相对独立，并无负载上的关联，但由于同时给定主速信号，在此大前提下，可根据各自的负载情况进行闭环型的速度调整，也能达到多台同速的要求。
