<P>PROBLEM TO BE SOLVED: To provide an inverter device capable of reducing the number of control terminals and of achieving a downsizing without a changeover switch provided. <P>SOLUTION: An inverter device comprises: an analog output circuit capable of changing an output voltage; an analog output terminal which outputs the output voltage of the analog output circuit to the outside; a reference potential terminal which specifies a reference potential of the analog output circuit; an output resistance connected between the analog output circuit and the analog output terminal; and a voltage detection part provided between the analog output terminal and the reference potential terminal. In the inverter device capable of outputting a voltage to an external device connected between the analog output terminal and the reference potential terminal in accordance with an operational status or an operating state, by applying the analog output voltage output from the analog output terminal to a sensor connected in place of the external device between the analog output terminal and the reference potential terminal, a divided voltage produced in the sensor is detected by the voltage detection part, and a protection operation is performed based on the detected voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
