Abstract

PURPOSE:To diagnose and display the malfunction of a chopper controller by comparing data obtained by sequentially operating the controller in quasi manner with a discrimination value stored in a memory. CONSTITUTION:A command from the central processing unit CPU of a malfunction diagnosing unit ANL is outputted through an input/output interface IOb to quasi control circuits GC, SL, CTC, DC, OC, thereby partly falsely operating a chopper controller CHP. Then, a voltage signal to be read in the controller CHP is inputted to the unit ANL through an analog input circuit AI and a digital input circuit DI. The inputted data is compared with a discrimination value stored in a memory, and the discriminated result is indicated on an indicator ID.
