ABNORMALITY MONITOR FOR CPU IN CONTROLLER OF TRAVELING OBJECT USING MOTOR

摘要

PROBLEM TO BE SOLVED: To prevent the reset of mutual CPU from being endlessly continued in a controller using plural CPU for monitoring each other. SOLUTION: Plural mutually connected CPU including first and second CPU 272 and 262 are used for controlling the operation of a motor. The first CPU 272 is provided with a first reset executing means for executing the first reset phenomenon causing reset in a prescribed range of circuit including the second CPU 262 when a reset signal is applied. The second CPU 262 is provided with a second reset executing means for supplying a reset signal to the first CPU 272 at the time of detecting the abnormality of the first CPU 272 without supplying any reset signal to the first CPU 272 when the second CPU 262 is reset in the first reset phenomenon.
