摘要： PROBLEM TO BE SOLVED: To detect a fault by comparing the actual state of a car and an output value irrespective of an input command value. SOLUTION: A fault decision means 4D of a main circuit control device 4 determines the occurrence of an abnormality when a value of a current flowing to a main motor 6 is less than 100 A though the speed of a car is determined as 'on accelerating' with not less than 0.3 m/s2. When a state that the value of the current flowing to the main motor 6 is less than 100 A continues for not less than 10 seconds, a counter counts 1 as the occurrence of one abnormality. When an abnormality successively occurs three times and the counter counts 3 and more, the fault decision means determines the occurrence of a fault and lights a fault-indicating light 5b by a notifying means 4H, or displays an indication of the occurrence of the fault in a monitoring means 5c to call attention of a trainman, a maintenance man or the like.

摘要： PROBLEM TO BE SOLVED: To evaluate acceleration in power running to detect the main control system state indirectly and estimate the loaded state on the main circuit system. SOLUTION: Each time the drive instruction is issued by the acceleration estimation means, acceleration estimation is carried out to detect the speed lower than the standard acceleration. When small acceleration is detected, it starts counting. If the frequency of running at low speed exceeds the set frequency during power run of certain times in the past, protection means controls the control means, and the current to the main motor is decreased lower than in the normal state (the normal acceleration other than the low speed run).
