直流辅助传动系统零点漂移浅析

Analysis on Zero─Point Drift of Aided Driving System of Direct Current

本文描述了直流辅助传动控制系统零点漂移（零漂）产生的原因，零速继电器与ＰＬＣ的关系，零漂与给定信号的关系，零漂对设备的影响及克服和合理的应用零点漂移，减小零漂对生产设备的危害，保证生产的正常运行．

The reason of causing zero point drift is described. The relationship between zero speed relay and PLC, zero point drift and given signal and its influence on the equipment are also elaborated. How we overcome it and how we use it reasonably are introduced so as to decrease its harm to the equipment and ensure normal production.
