PROBLEM TO BE SOLVED: To provide an inverter device, in which a variety of peripheral equip ment can be connected, without adding signal conductors to each interface section of a control board and which can correspond to diverse applications. SOLUTION: Even if a main circuit board 14L having the different kinds of machines such as a low-functionality types, general-purpose types and high- functionality-type can be connected in common with control board 21, by constituting an interface section 26 for driving as the connectors of 22 pins and defining the connection number of the interface section 26 as a 'a current-detecting signal (form discrimination)', and a control circuit 22 conducts control for each kind of machines by starting different control programs through referring to the voltage level of 'a current-detecting signal 2' and discriminating the machines kinds of a main circuit section 9 and a drive circuit section 10L are connected. |
