Claim Text:
1. An abnormality diagnosis device for a servo control device that is connected to the servo control device and a statistical data server, the abnormality diagnosis device comprising: a factor-data storage unit that stores therein factor data including at least one candidate of an alarm-generating factor corresponding to an alarm number that indicates a type of an alarm in the servo control device and a counter-alarm measure to handle the alarm-generating factor; a stored-data storage unit that stores therein, as stored data, statistical data acquired from the statistical data server, the statistical data including the alarm number corresponding to a system configuration number of the servo control device classified based on a system configuration of the servo control device, a candidate of the alarm-generating factor corresponding to the alarm number, and a generation probability of the candidate of the alarm-generating factor; a display unit; and an abnormality-diagnosis processing unit that acquires the alarm number from the servo control device when an alarm is generated, and based on the alarm number, the factor data, and the stored data, adds the generation probability, a search method for the alarm-generating factor, and the counter-alarm measure to each of the at least one candidate of the alarm-generating factor and displays, on the display unit, the candidate of the alarm-generating factor with the generation probability added.
