B60P8000-2 overvoltage protection cannot reach the required 73.5V.
The inverter can start and run normally, but overvoltage protection is carried out at more than 70 volts, which cannot reach the required 73.5V.
Solutions and steps
1，The overvoltage protection value setting on the front control board is too low.
Change the R13 resistance on the front control board and adjust the overvoltage protection value to 73.5V.
