Abstract
A self diagnosis method and control apparatus for positive self diagnosis of equipment having complicatedly interlaced mechanical portions. Equipment under diagnosis is divided into a plurality of areas under diagnosis, each of which is assigned an evaluation variable. Diagnosis is executed in units of diagnostic steps classified for each area under diagnosis. Based on an execution result, points are allotted to the evaluation variable. Based on the evaluation variable, or a sum of allotted points, each area under diagnosis is diagnosed and a diagnostic result is displayed for self diagnosis. Meanwhile, those diagnostic steps which are determined invalid by an execution result of another diagnostic step will not be executed. The equipment under diagnosis includes those which contain mechanical portions.
