Input phase loss failure is one of the common failures of inverters, involving the input detection of three-phase products. Output phase loss will lead to motor failure, the motor current will increase by 1.2 times, and the heat will be serious.
Input Input Phase Loss Fault Overview
Input phase loss fault is one of the common faults of inverters, which involves the input detection of three-phase products.
Output phase loss impact
Output phase loss will cause motor failure, the motor current will increase by 1.2 times, and the heat will be serious.
Enter the phase detection method
The input phase loss detection can be judged by observing the change of Udc voltage waveform.
Software detection method
The software detects the phase loss by analyzing the periodic changes of the Udc AC component.
