伺服电机运行时出现异常声音或抖动现象，如何处理?①伺服配线: a.使用标准动力电缆，编码器电缆，控制电缆，电缆有无破损; b.检查控制线附近是否存在干扰源,是否与附近的大电流动力电缆互相平行或相隔太近; c.检查接地端子电位是否有发生变动，切实保证接地良好。② 伺服参数: a.伺服增益设置太大，建议用手动或自动方式重新调整伺服参数; b.确认速度反馈滤波器时间常数的设置，初始值为 0，可尝试设置值; c.电子齿轮比设置太大，建议恢复到出厂设置: d.伺服系统和机械系统的共振，尝试调整陷波滤波器频率以及幅值。③机械系统: a.连接电机轴和设备系统的联轴器发生偏移，安装螺钉未拧紧: b.滑轮或齿轮的咬合不良也会导致负载转矩变动，尝试空载运行，如果空载运行时正常则检查机械系统的结合部分是否有异常 c.确认负载惯量，力矩以及转速是否过大，尝试空载运行，如果空载运行正常，则减轻负载或更换更大容量的驱动器和电机。410-4 MODICON CONTROLLERS REMANUFACTURED
