Hi
check the main voltage supply. If the fuses are ok and you not have DC voltage at DC bus, probably you have one damage on the input rectifier bridge in your drive.
Please do not forget that to better understand your problem, it would be advisable for you to describe the size of the inverter, if it is a drive that has already worked, if there have been events that may have caused the problem you describe.
Furthermore, IMHO the convenience of repair also depends on the size of the drive, on small sizes the costs of labor and spare parts sometimes do not justify a repair.
Hope this help you
