PROBLEM TO BE SOLVED: To provide an inverter device which can perform a test trial operation of a monitor output function beforehand even in the state where a load cannot be operated, and can perform a test trial operation of a program of a control system using monitor output.SOLUTION: When performing a test trial operation of a monitor output function for a wiring connection or a signal line of a monitor output signal in a state where a load cannot be operated and when performing the test trial operation of the monitor output function beforehand according to a control program that is updated during periodic maintenance, a simulation operation mode is commanded to the inverter device. In a state where output of a switching signal to an inverter circuit is prohibited by output prohibition means, simulation operation means executes the simulation operation mode in which a parameter stored in parameter storage means is output to monitor output means. Thus, since the monitor output means outputs the parameter as a monitor value, the monitor output function can be inspected by confirming the parameter.SELECTED DRAWING: Figure 2 |
