Press the operation panel to display OE; the indication shows DC overvoltage. The voltages of the three phases are normal, and it is not possible to measure the voltage at the DC terminals

OE is a DC overvoltage; the possible causes are: 1. Fault in the DC voltage detection circuit; 2. Fault in the rectification circuit; 3. Aging of the smoothing capacitor.
