Electrical parts themselves caused by quality problems, these problems often appear after the use of equipment for a period of time, without any early warning, these faults are often caused by the quality of the winding machine manufacturer's products themselves. In the normal use of the winding machine, the user should pay close attention to the various running conditions of the equipment, whether there is abnormal noise, smell and other abnormal conditions, early detection of problems can be controlled in a small range of fault.

   Winding vendors would winding machine is the collection of electrical control and precision machinery electrical equipment, so a high requirement on the environment and supporting the power, because the factory power supply load characteristic determines the existence of a series of impact and interference, is among the common electromagnetic interference, interference often frequent downtime, driven by the winding machine setting parameters not to keep or field, such as chaos, and in a short period of time of equipment is of no effect, but the coiling machine long-term excessive grid disturbance pulse, the controller internal components such as the occurrence of premature aging and failure.

   Common electric actuating parts are in winding machine controller, inverter, spindle motor, stepping motor, electromagnetic brake, electromagnetic valve, etc., these are also at the heart of the factory house of the winding machine winding electric components, they play an important role in the performance of these parts at the same time also determines the working performance of the winding machine, the controller is the brains of the winding machine which is responsible for control power, wiring, etc., at present there are two types of common winding machine controller, one is general controller by integrating suppliers, another kind is their own research and development of the controller, the controller generally common failures are high voltage control part and buttons, General users can not solve these problems themselves, need to notify the manufacturer to repair; Inverter fault is more common, you can view the inverter display interface to judge the fault; Motor fault users should pay attention to the motor in the process of use whether there is abnormal sound, temperature rise is normal to judge, the use of equipment to prevent overload work; Brake belong to vulnerable parts, in the winding machine after a period of time should be timely adjustment, replacement if necessary.

   Among the reasons why the main motor cannot start normally due to the differential protection of the protection device, except the motor's own fault, most cases are caused by the differential protection circuit. In the actual production process, due to the large vibration of the vertical mill, differential protection tripping is likely to occur due to the loose connection terminal of the current transformer on the motor side. Therefore, during the maintenance of equipment at ordinary times, it is an important maintenance to tighten the connection terminal of the current transformer on the motor side.
