| 粉末机械主电机不能启动 I. The main motor of powder machine cannot be started 产生原因：开车程序有错。主电机线程有问题，熔断丝是否被烧环。 Cause: wrong driving procedure. There is a problem with the main motor thread and whether the fuse is burnt. 处理方法：检查程序，按正确开车顺序重新开车。检查主电机电路。检查润滑油泵是否启动，检查与主电机相关的连锁装置的状态。变频器感应电未放完，关闭总电源等待5分钟以后再启动。检查紧急按钮是否复位。 Handling method: check the procedure and restart according to the correct starting sequence. Check the main motor circuit. Check whether the lubricating oil pump is started, and check the status of the interlocking device related to the main motor. The induction power of the frequency converter is not discharged, turn off the main power supply and wait for 5 minutes before starting. Check whether the emergency button is reset. 二、主电机发出异常声音 II. Abnormal sound from main motor 产生原因：粉末机械主电机轴承损坏。主电机可控硅整流线路中某一可控硅损坏。 Cause: main motor bearing of powder machine is damaged. One of the thyristors in the main motor thyristor rectifier circuit is damaged. 处理方法：更换主电机轴承。检查可控硅整流电路，必要时更换可控硅元件。 Treatment: replace the main motor bearing. Ch |
