财产损失或经济损失。电击危险标签可能位于驱动器上或内部，以提醒人们可能存在危险电压。第1章介绍手册目标本文档旨在作为1336 PLUS 6.1故障排除指南的补充补充。本补充内容涵盖了您需要的其他信息，以帮助排除或维修Allen-Bradley Bulletin 1336 PLUS II可调频率交流驱动器（A1-A4框架）。谁应该使用本手册本手册适用于负责1336 PLUS II可调频率交流驱动器故障排除和维修的合格维修人员。您应该：•在对驱动器进行维护或维修之前，请阅读整个手册。•具有电气术语、程序、所需故障排除设备、设备保护程序和方法以及安全预防措施的经验和基本理解！注意：某些印刷电路板和驱动组件可能包含危险的电压水平。在断开或重新连接电线之前，以及在拆除或更换保险丝和电路板之前，请断开并锁定电源。通过测量端子块TB1上的+DC和-DC之间的电压来验证总线电压。在总线电压放电到零伏之前，不要尝试维修驱动器。注意：不当使用示波器和其他测试设备可能会导致潜在的致命电压。如果未正确接地，示波器机箱可能处于潜在的致命电压。如果使用示波器测量高电压波形，则在X 100探头的差分模式下仅使用双通道示波器。建议示波器在A减B准差分模式下使用，示波器底盘正确接地。注意：只有熟悉1336 PLUS II交流驱动器和相关机械的人员才能计划或实施系统的安装、启动和后续维护。不遵守可能导致人身伤害和/或设备损坏。1336 PLUS-6.16-2001年9月1-2简介静电放电静电产生的静电放电会损坏各种驱动板上的互补金属氧化物半导体器件。建议您执行以下步骤，以防止在拆卸或安装电路板时发生此类损坏：•佩戴与驱动器底盘接地的腕带。•连接腕带
, property damage, or economic loss. Shock Hazard labels may be located on or inside the drive to alert people that dangerous voltage may be present. Chapter 1 Introduction Manual Objectives This document is intended as a supplementary addition to the 1336 PLUS 6.1 Troubleshooting Guide. This supplement covers the additional information you will need to help troubleshoot or repair an Allen-Bradley Bulletin 1336 PLUS II Adjustable Frequency AC Drive with A1 - A4 Frames. Who Should Use This Manual This manual is intended for qualified service personnel responsible for troubleshooting and repairing the 1336 PLUS II Adjustable Frequency AC Drive. You should: • Read this entire manual before performing maintenance or repairs to drives. • Have previous experience with, and basic understanding of, electrical terminology, procedures, required troubleshooting equipment, equipment protection procedures and methods, and safety precautions. ! ATTENTION: Some printed circuit boards and drive components may contain hazardous voltage levels. Remove and lock out power before you disconnect or reconnect wires, and before you remove or replace fuses and circuit boards. Verify bus voltage by measuring the voltage between +DC and -DC on Terminal Block TB1. Do not attempt to service the drive until the bus voltage has discharged to zero volts. ATTENTION: Potentially fatal voltages may result from improper useage of oscilliscope and other test equipment. The oscilliscope chassis may be at a potentially fatal voltage if not properly grounded. If an oscilliscope is used to measure high voltage waveforms, use only a dual channel oscilliscope in the differential mode with X 100 probes. It is recommended that the oscilliscope be used in the A minus B Quasi-differential mode with the oscilloscope chassis correctly grounded to an earth ground. ATTENTION: Only personnel familiar with the 1336 PLUS II AC Drive and associated machinery should plan or implement the installation, start-up and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage. 1336 PLUS - 6.16 - September, 2001 1-2 Introduction Electrostatic Discharge Electrostatic discharge generated by static electricity can damage the complimentary metallic oxide semiconductor devices on various drive boards. It is recommended that you perform these procedures to guard against this type of damage when circuit boards are removed or installed: • Wear a wrist-type grounding strap that is grounded to the drive chassis. • Attach the wrist strap
