Delta VFD inverters have established extensive brand recognition in the industrial automation market. Each series of products is designed for different operational needs such as torque, loss, overload and overspeed operation, and is adjusted according to different industrial machinery properties; it can provide customers with diversified choices and is widely used in industrial automation control. It has the characteristics of high power-to-volume ratio, excellent quality and the ability to develop special products for different industries.
Tada inverter overcurrent fault: Overcurrent fault can be divided into acceleration, deceleration, constant speed overcurrent. It may be caused by the acceleration/deceleration time of the inverter being too short, the load is abrupt, the load is not evenly distributed, and the output is short-circuited. At this time, it is generally possible to extend the acceleration/deceleration time, add energy-consuming braking components, perform load distribution design, and inspect the line. If the load inverter is disconnected or the overcurrent fault occurs, the inverter inverter circuit has been looped and the inverter needs to be replaced.
A Delta Inverter Overload Fault: Overload faults include variable frequency overload and motor overload. It may be caused by the acceleration time being too short, the grid voltage being too low, and the load being too heavy. Generally, the acceleration time can be extended, the braking time can be extended, the grid voltage can be checked, and the like. If the load is too heavy, the selected motor and inverter cannot be dragged by the load, or it may be caused by poor mechanical lubrication. If the former, the high-power motor and inverter must be replaced; if the latter, the production machinery should be repaired.
Inverter undervoltage of Delta: It indicates that there is a problem with the input part of the inverter power supply, and it needs to be checked before it can run.
The output of Delta's inverter is ignited: After disassembling and checking, it is found that the IGBT inverter module breaks down, and the printed circuit board of the drive circuit is seriously damaged. The correct solution is to first remove the damaged IGBT inverter module. When disassembling, the printed circuit board should be protected from artificial secondary damage as much as possible. The damaged electronic components on the drive circuit should be replaced one by one and the open circuit on the printed circuit board should be connected with wires (this should be noted to burn) The part is scraped clean to prevent re-ignition.) The resistance of the six-way drive circuit is the same. When the voltage is the same, the waveform is measured by the oscilloscope. However, when the inverter is turned on, the OCC fault is reported. Variable module open opportunity alarm) Use the light bulb to connect the P1 and the printed board of the module. The other wires are connected, restarted and jumped again. It is determined that there is still a problem with the drive circuit. The optocoupler is replaced one by one, and the optocoupler of the drive circuit is found. With detection function, one of the optocoupler detection functions is damaged. After replacing the new one, it starts normally.
