伺服电机失速有哪些原因？

<p>1、速度反馈的极性搞错；&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</p><p>2、编码器速度反馈时，编码器电源失电。处理方法：检查连接5V编码器电源。确保该电源能提供足够的电流。如使用外部电源，确保该电压是对驱动器信号地的。</p>
