设计了一种基于频压变换芯片VFC320的超速检测装置,该装置可将编码器信号的频率线性地转换为电压信号,逻辑电路部分由可编程逻辑器件完成,为安全性要求高的运动控制系统提供了一路冗余保护信号。
An overspeed detection device based on VFC320 is designed. The device can convert the frequency of encoder signal into voltage signal linearly, and the logic circuit is partly realized by programmable logic device. It is a safety-oriented motion control system Provides all the way to redundant protection signals.
