However, inverters may encounter various faults during operation. This article will introduce the common faults of inverters in detail, including electrical quantity faults, current problems, frequency and voltage problems, internal component faults, grounding faults and other problems, and provide corresponding solutions. 1.
In addition to the above common faults, the inverter may also encounter other problems, such as communication failure, overheating failure, etc. These problems may be caused by various factors such as equipment design, manufacturing process, and use environment. Handling method:
The system does not store minor faults; the alarms are automatically cleared once the fault disappears. When a minor fault alarm occurs during inverter operation, the system will not shut down. 3. What are the major faults?
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.
What is an Overvoltage Error? Inverters use DC bus capacitors to store electrical energy. When the voltage on the DC bus exceeds the permissible threshold (typically > 400V for 3-phase 220V
