ABSTRACT:
Objects of the present invention are to provide an inverter apparatus in which the specification thereof can be readily changed without changing an inverter basic unit, and to provide an inverter apparatus in which an inverter basic unit and an I/O block unit can be readily separated and the number of degrees of freedom of installation can be increased. An inverter apparatus of the present invention is constituted by an inverter basic unit and an I/O block unit which is connected to the inverter basic unit separately therefrom. The inverter basic unit is constituted by a power module which includes a DC/AC converter and a controller including a microcomputer for managing the DC/AC converter. The I/O block unit is constructed in the form of an I/O block unit which includes an input/output interface unit having signal connection terminals. Since the plurality kinds of I/O block units can be connected to the inverter basic unit and also the software of the microcomputer can be changed with the microcomputer mounted on the associated substrate, the specification and the performance of the inverter apparatus can be readily changed.
