PROBLEM TO BE SOLVED: To solve the problem that processing is complicated in the case of verifying suitability of processing in each of controllers when plural controllers exist. SOLUTION: Suitability of processing in two CPUs is divided to that to be verified by one CPU itself and that to be verified by the other CPU. Whether an arithmetic and logic operating circuit in a main motor control CPU 262 rightly operates or not, for example, is decided by judging the result operated by an arithmetic and logic operating block 404 while using a value stored in a ROM 402 for constant storage by a comparing part 410 provided in a master control CPU 272. In this case, the main motor control CPU 262 verifies suitability of a signal inputted thereto by judging the range of its value or the like. It is not necessary for the master control CPU 272 provided in the other control part to receive data or signal inputted by the main motor control CPU 262 and processing can be simplified. |
