Check DC buss voltage. If DC Voltage is 141% of input voltage check the DC wave form and verify that it is good. If all of input is good and output IGBT's fail to fire make sure that programing is intact. If you are sure that the drive is not overheating for some reason.. Then replace the main board. Does the drive give you any alarms??? Fuji has an excellent technical support team.
