What causes a DC inverter to overvoltage?
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. Check supply voltage for constant or transient high voltage. Increase deceleration time.
Can a DC inverter overvoltage be measured?
One thing to keep in mind with the overvoltage fault is that it only happens instantaneously at a certain time. Therefore you can only monitor the DC bus voltage stored on the inverter at the time of failure, it is not possible to measure the overvoltage at this time.
How to check if an inverter is overvoltage?
Then measure the input voltage or check the DC bus parameter at fault (you can check this parameter in the monitor parameter set of the inverter). Input overvoltage of the inverter is usually caused by a problem with the substation that increases the voltage at the inverter power supply.
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.
