检查系统参数设置是否正确 1、参数设置对伺服系统的性能影响很大,因此,必须按照设定要求来进行参数设置。如果参数设置错误,将会造成电机运行不正常或机械传动机构不能正常工作等问题。 2、在伺服驱动系统中,用户经常需要对一些重要的参数进行设定,如速度设定、位置设定等,如果这些重要参数不正确或设定错误将会导致电机运行出现问题。 3、为了提高伺服系统的控制性能,可以将某些伺服电机的驱动程序增加一些参数设置。 4、为了使系统工作可靠,有必要检查和测试伺服电机的各种保护功能是否有效。 5、当伺服系统出现故障时,应及时停止设备运行并进行修理。 检测伺服电机的参数是否有变化 1、伺服电机参数包括:负载扭矩、输入频率、转矩/速度比、大转矩/转速、输出电压(V)和电流(A)等; 2、如果有变化,应该根据伺服电机的型号和参数设置来设定; 3、如果参数变化,先检查电源是否正常,然后检查伺服电机和驱动器的连接是否正常,后再检查伺服电机的参数设置是否正确。 对电机进行启动试验 1、接通电源,观察电流表的示数,观察电机的转动方向和有无异常现象。 2、用万用表测量电机的绝缘电阻值,不得低于2MΩ。 3、用示波器观察电机的启动过程,在启动过程中检查电流是否正常,有无冲击及过流现象。 4、用示波器观察电机转子转速信号是否正常。
