PURPOSE:To detect anomaly such as non-measured place or no-measuring in an early stage. CONSTITUTION:A temperature sensor 12 for detecting the temperature of a load motor 3 is provided. When an endurance test is started, the temperature detected by the temperature sensor 12 is stabilized and becomes constant after the elapse of a certain time. Thereafter, if any abnormal mechanical loss occurs in the mechanism of torque sensor 4, reduction gear 5, coupling 6 and so forth, the load of a load motor 3 becomes lighter and the temperature drops temporarily. This drop is found by the temperature sensor 12, and the host computer 11 judges 'presence of anomaly in the mechanism'. |
