    • 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.
    • 本发明的目的是提供一种逆变器装置,其中可以容易地改变其规格而不改变逆变器基本单元,并且提供一种逆变器装置,其中逆变器基本单元和I / O块单元可以容易地分离 并且可以增加安装的自由度。 本发明的逆变器装置由与逆变器基本单元分开连接的逆变器基本单元和I / O块单元构成。 逆变器基本单元由包括DC / AC转换器的电源模块和包括用于管理DC / AC转换器的微计算机的控制器构成。 I / O块单元以I / O块单元的形式构成,其包括具有信号连接端子的输入/输出接口单元。 由于可以将多种I / O块单元连接到逆变器基本单元,并且也可以通过安装在相关基板上的微型计算机来改变微型计算机的软件,因此可以容易地改变逆变器装置的规格和性能 。
