三菱plc编码器梯形图程序
旋转编码器的通常介绍

　　其首要有两种,一种是增量型,另一种是推重型。增量型的特征是只需在旋转时期会输出对应旋转视点脉冲,间断是不会输出。它是运用计数来丈量旋转的办法；报价比照廉价。推重型的的特征是不管是不是旋转,能够将对应旋转视点进行平行输出的类型,不需求计数器可供认旋转方位；它还有不受机械的晃动或轰动以及开关等电器烦扰的功用,报价贵。在挑选运用时,可参阅以下几点。包含本钱、分辩率、外形规范、轴负荷及机械寿数、输出频率、环境、轴旋转力矩、输出回路等等。

运用举例

　　它通常运用在对机器的动作操控。我那一个实例具体阐明一下。我刚刚改造一台机器,机器在作业进程中先要对工件进行处理,然后加工。它早年是用光电开关做的,机器的电路就比照杂乱,并且本钱添加,保护调校费事。所以我就对机器的电路进行改造,首要是用一个编码器来替代早年的光电开关。此套体系由OMRON的PLC与编码器构成。下面是PLC程序。
