STATUS DIAGNOSING SYSTEM FOR ROLLING GUIDE DEVICE AND STATUS DIAGNOSING METHOD

摘要

The state diagnosis system including: a sensor configured to detect a physical quantity exhibited when the moving member is moving along the track member; and a diagnosis processing unit configured to take in an output signal from the sensor, to thereby generate analysis data, compare the analysis data with threshold value data, determine whether the rolling guide device has an abnormality in accordance with a comparison result, and output a determination result, wherein the diagnosis processing unit has: a first processing mode of taking in the output signal from the sensor for a data collection time period T1, to thereby generate the analysis data; and a second processing mode of taking in the output signal from the sensor for a data collection time period T2 longer than the data collection time period Ti, to thereby generate the analysis data, and wherein the diagnosis processing unit outputs the determination result.
