Common faults of the inverter one, 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 inverter acceleration and deceleration time, reduce the sudden change of the inverter load, add the energy consumption braking component, carry out the load distribution design, and check 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.
Inverter common fault 2, overload fault: overload fault includes inverter 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 common fault three undervoltage: It indicates that there is a problem in the input part of the inverter power supply, and it needs to be checked before it can run.
The common faults of the inverter are the above, please refer to it.
