<P>PROBLEM TO BE SOLVED: To solve the problem that in outputting command value information from an ECU 30 to each of conversion microcomputers 46a, 46b, 46c for operating each of a plurality of inverters INVa, INVb, INVc, the number of communication means increases, which may cause increase the size and cost of an apparatus. <P>SOLUTION: An ECU 30 outputs command values of each of inverters INVa, INVb, INVc to a communication microcomputer 44 through an external communication line Lc1 and a photocoupler 42. A communication protocol used at this time is LIN. The communication microcomputer 44 changes a format of received data to I2C and outputs it to conversion microcomputers 46a, 46b, 46c. <P>COPYRIGHT: (C)2013,JPO&INPIT |
