First, the winding machine failure caused by electromagnetic interference
The winding machine is an electrical equipment integrating electrical control and precision machinery. Therefore, the requirements for the environment and supporting power supply are very high. Due to the load characteristics of the factory power supply, there are a series of shocks and disturbances, the most common of which is electromagnetic interference. The winding machine is frequently stopped due to its interference, and the set parameters are not saved or chaotic. It has no effect on the equipment in a short time, but the winding machine has been subjected to excessive power grid interference pulses for a long time, so that the controller is internally Premature aging and failure of components.
Under normal circumstances, it can solve this problem well by separately supplying power to the winding machine or adding a capacitor.
Second, the winding machine failure caused by excessive grid fluctuations
Any equipment has a rated working range. If it exceeds the rated range, equipment anomalies will occur. Under the influence of excessive grid fluctuations, the controller, inverter and sensor of the winding machine will be abnormal. The main performance is that the controller has no Output signal, the inverter has an overvoltage or undervoltage alarm. For the inspection of the grid, the oscilloscope can be used to check the grid voltage waveform. If the grid fluctuation is too large, corresponding measures should be taken to avoid equipment anomalies.
A conventional approach is to add an AC voltage regulator to the power input of the winding machine.
Third, the fault caused by the abnormal input of the external signal
The winder controller will perform system self-test after power-on to detect whether the signal of the peripheral sensor is normal. Whether the normal start-up work depends on the position sensor of the cable system and the signal input of the operation panel button. When the sensor signal is abnormal, the controller The error code will be displayed. The signal of the external button needs to be judged by the detection tool. After the fault is removed, the controller can start normally.
