<p>Even when an inverter device cannot be connected to a commercial power source or a control power source is cut off, it is possible to check and modify the setting state of a microcomputer and a peripheral circuit of the inverter device. The inverter device includes external power source unit connection connectors (24, 45, 30, 46, 41, 51) capable of connecting external power source units (32, 48) to one of an inverter main body (1), a built-in option (37), and a parameter unit (27). The external power source unit connection connectors (24, 45, 30, 46, 41, 51) are connected to the control power source.</p> |
