Causes and solutions to the failure of no output voltage of SEW inverter
The causes of no output voltage failure of SEW inverter can generally be divided into two categories: internal fault and external fault.
1.1 Internal Failures.
Internal fault refers to the damage caused by the internal electronic components or modules of the inverter, such as IGBT module failure, control circuit failure, etc.
1.2 External faults.
External faults refer to faults caused by the external environment or equipment around the inverter, such as unstable power supply voltage, overload, overheating, etc.
2.The solution to the failure of the output voltage of the SEW inverter.
2.1 Resolution of internal failures.
For internal faults, careful fault diagnosis and repair are required, and the faulty component or module may need to be replaced, which requires a professional technician to operate.
2.2 Resolution of external failures.
For external faults, it is necessary to check one by one from the aspects of power supply and load to ensure that the environment and equipment around the inverter are in good working condition.
3.Precautionary measures.
3.1 Regular check-ups.
Regular inspection and maintenance of the SEW inverter, timely detection and solution of problems, can effectively prevent the occurrence of no output voltage failure.
3.2 Increase overload protection.
In the design and use of the inverter, the overload protection and short-circuit protection functions are added, which can effectively reduce the failure rate of the inverter.
