Abstract
PURPOSE:To enable clearing up the cause of a failure on the basis of the kind and order of occurrence of said failure also in a state where the power is OFF, by storing a non-volatile storage element with the kind and order of occurrence of a failure at the time of its occurrence. CONSTITUTION:An inverter controller 6 controls an inverter 1 according to a detection signal from a sensor part 5. When an abnormality occurs, a storage element RAM is cause to store the kind and order of occurrence of a failure. When the power is OFF, the kind and order of occurrence of a failure stored in the storage element RAM are transferred to a non-volatile storage element NVRAM 9 which is then caused to store said data. When the power is again ON, the order of occurrence of an abnormality having occurred before the power was cut OFF, which is stored in the non-volatile storage element NVRAM, is indicated in a display 7.
