Inverter apparatus having a separate controlling application program for performing specification dependent control

Abstract

An inverter apparatus which is capable of easily structuring a controlling program for controlling the inverter apparatus to cope with various specifications. The inverter apparatus is comprised of a control section including a CPU 1 serving as a computing means for controlling a converter unit 31 and an inverter unit 33, a memory 2, a memory 3 serving as a first storage unit for storing an inverter-controlling basic program, a parameter storage unit 4 for storing parameters, and an AP S/W storage unit 5 serving as a second storage unit for storing a plurality of inverter-controlling application programs, and a display device 6 for such as a parameter unit and having a display portion and an input portion. An inverter-controlling application program is transferred from outside the inverter apparatus to the AP S/W storage unit 5 through a telecommunication means.
