What are the most common faults on inverters?
In this article we look at the 3 most common faults on inverters and how to fix them: 1. Overvoltage and Undervoltage Overvoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage.
What causes overvoltage & undervoltage?
1. Overvoltage and Undervoltage Overvoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on.
What is inverter over-voltage protection?
Everyone often encounters the problem of inverter over-voltage protection when dealing with inverter faults. The over-voltage of the inverter means that the inverter voltage exceeds the rated voltage. The over-voltage protection of the inverter is caused by the over-voltage of the inverter.
What is overvoltage error?
Overvoltage error in English is called Over Voltge (OV), so with common inverter lines, it will be reported as OV or OV1-2. As for the inverters made by some manufacturers, the inverters with overvoltage error are recorded as E7 (E here is error) or F4 (F stands for Fault).
What does overvoltage mean in an inverter?
The over-voltage of the inverter means that the inverter voltage exceeds the rated voltage. The over-voltage protection of the inverter is caused by the over-voltage of the inverter. There are two main reasons for the inverter overvoltage: the inverter power supply overvoltage and the inverter regenerative overvoltage.
What causes inverter overvoltage?
There are two main reasons for the inverter overvoltage: the inverter power supply overvoltage and the inverter regenerative overvoltage. The overvoltage of the power supply means that the DC bus voltage exceeds the rated value because the power supply voltage is too high.
