对于伺服控制系统都需要配备速度反馈及位置反馈的编码器,我们在选择编码器时,不仅要考虑编码器的类型,还要考虑编码器的接口、分辨率、精度、防护等级等方面,以满足用户的控制要求。尤其是编码器的分辨率和精度与运动控制有着密切的联系,今天我们就跟大家聊聊伺服编码器的分辨率和精度。分辨率(resolution)分辨率是指编码器每个计数单位之间产生的距离,它是编码器可以测量到的最小的距离。对于旋转编码器来说,分辨率一般定义为编码器旋转一圈所测量的单位或者脉冲(如,PPR)。
其他结构:根据使用场合、用户要求,可提供各种形式的电缆,以满足各种敷设环境条件的要求。综合布线、安防工程、监控工程、弱电系统工程、银行监控、网络工程、音响工程、远程三表抄送、消防工程、楼宇防盗监控、门禁可视对讲等专用、音、视频电线电缆。

举个简单的例子更加容易说清楚:按钮或者接近开关的接线所示:PLC开关量接线,一头接入PLC的输入端(X0,X1,X2等),另一头并在一起接入PLC公共端口(COM端)。模拟量信号:一般为各种类型的传感器,:压力变送器,液位变送器,远传压力表,热电偶和热电阻等等信号。模拟量信号采集设备不同,设备线制(二线制或者三线制)不同,接线方法也会稍有不同输出端口接线PLC输出端口接线一般可以分为以下三种情况:继电器输出晶体管输出晶闸管输出PLC输出方式不同,输出负载所接的电源类型也不同。
