安装说明原版说明书译文Hiperface-to-DSL 反馈整流器套件产品目录号 2198-H2DCK变更摘要在后盖板增加了 EAC 徽标。
关于反馈整流器套件本套件适用于 Allen-Bradley® 2090 系列电机反馈电缆，且配备 10 个 Hiperface 编码器信号的接线端子。
Hiperface 编码器信号被转换成兼容的数字伺服链路 (DSL) 反馈信号。
必须为 10 针整流器套件连接器接线，并在正确放置电缆屏蔽层和电缆护套的情况下组装连接器壳体。
准备电缆如要将反馈整流器套件用于现有 Bulletin 2090 电缆，需要进行一些准备工作，以确保电缆屏蔽层、导线长度和剥线长度正确无误。
准备反馈电缆时，请遵循以下说明：•将屏蔽层修剪平整，以免绞线造成相邻端子短路。
•测量导线长度，确保其足够长，以提供工作回路。
•在每根导线上将剥掉足够长的屏蔽层，以提供合适的剥线长度。
反馈电缆尺寸单位为 mm (in.)在电缆护套上的位置2罗克韦尔自动化出版物 2198-IN006D-ZH-P - 2019年10 月Hiperface-to-DSL 反馈整流器套件安装整流器套件按照以下步骤安装整流器套件。
1.拆下保护盖，将信号线连接至合适的端子，为每个连接端留出工作回路。
有关 10 针端子插脚引线，请参见第 第3 页 页的 连接器数据。
2.以 0.25 N•m (2.2 lb•in) 的最大扭矩，拧紧端子螺丝。
3.将屏蔽夹夹到 12 mm (0.5in.) 的裸露电缆屏蔽层上，以在屏蔽编织层和屏蔽夹之间实现高效搭接。
4.连接扎带 (随套件一起提供)，以消除应力。
5.以 0.3 N•m (2.6 lb•in) 的最大扭矩，拧紧屏蔽夹螺丝。
6.更换保护盖，然后安装保护盖螺丝。
以 0.3 N•m (2.6 lb•in) 的最大扭矩，拧紧保护盖螺丝。
7.将 2 针 DSL 连接器插入驱动连接器，然后将安装支架安装到其中一个安装位置 (共 3 个) 上。
汽车起重机平衡回路分析
5.方茴说：“那时候我们不说爱，爱是多么遥远、多么沉重的字眼啊。
我们只说喜欢，就算喜欢也是偷偷摸摸的。
”6.方茴说：“我觉得之所以说相见不如怀念，是因为相见只能让人在现实面前无奈地哀悼伤痛，而怀念却可以把已经注定的谎言变成童话。
”7.在村头有一截巨大的雷击木，直径十几米，此时主干上唯一的柳条已经在朝霞中掩去了莹光，变得普普通通了。
8.这些孩子都很活泼与好动，即便吃饭时也都不太老实，不少人抱着陶碗从自家出来，凑到了一起。
9.石村周围草木丰茂，猛兽众多，可守着大山，村人的食物相对来说却算不上丰盛，只是一些粗麦饼、野果以及孩子们碗中少量的肉食。
汽车起重机平衡回路分析一.前言在液压系统工作时，如果液压缸或液压马达的负荷为垂直水平的载荷，并且运动方向和重力与作用力方向一致时，就要用平衡阀使回路上产生油流阻力，防止运动失去控制。
平衡阀在液压起重机的起升、变幅和伸缩油路中应用较多。
例如在起升油路中，重物下降时，如果在起升马达的回路上没有设平衡阀，则在重力作用下，液压马达会越转越快，甚至产生事故。
平衡回路要求结构简单，闭锁性能好，工作可靠无冲击。
二.平衡回路作用任何平衡回路工作过程中,均有三种运动状态：即举重上升、承载静止、负载下行。
1.举重上伸在汽车起重机的伸缩、变幅、起伸3种机构中，平衡阀前端(油源方向)经高压软管与中心回转接头、操纵阀相连，后端经高压钢管与执行元件、液压缸或马达相连。
当机构运动方向与负载重力作用方向相反时，即当外伸、起升、变幅缸上举时，平衡阀只起通路作用，同时，执行元件有杆腔液压油经另一条油路流回油箱;当平衡阀与手动换向阀之间的管路(多为高压软管)损坏漏油时，平衡阀能封闭无杆腔油液，使负载停留在空中原位置不动，避免造成坠落事故，可起到安全保护作用。
2.承载静止当机构停止工作时，平衡阀内部油路被锁死封闭，其顺序阀也是完全关闭的，截止了执行元件的回油路，使机构和负载按需要停留在任意位置，称其为“位置锁定”。
