Condition-detecting device, method, and program, and information-recording medium

摘要

There is provided a condition detection apparatus for detecting a present operating condition of a linear rolling motion guide apparatus, and the condition detection apparatus includes an AE sensor 1 for detecting a waveform elastically generated at least due to rolling of balls included in the linear rolling motion guide apparatus and mutual collision of the balls and generating an electric detection signal corresponding the detected waveform, a waveform shaping unit 2 , an A/D converter 3 , and a signal processing unit 4 judging a content of the operation condition in response to the generated detected signal Sae.
