To highly accurately diagnose a state of a motion guide device having track members and movement members.SOLUTION: A parameter acquisition section acquires a predetermined diagnostic parameter correlated with a friction force fluctuation to occur when movement members move on track members in a motion guide device. A signal processing section extracts a first diagnostic signal being the signal of a first predetermined frequency band and a second diagnostic signal being the signal of a second predetermined frequency band that is lower than the first predetermined frequency band, from a signal related to a predetermined diagnostic parameter. A diagnosis section diagnoses a state of the motion guide device on the basis of the first diagnostic signal and the second diagnostic signal.SELECTED DRAWING: Figure 11 【課題】本発明は、軌道部材と移動部材を有する運動案内装置の状態をより高精度で診断することを目的とする。【解決手段】パラメータ取得部が、運動案内装置において軌道部材上を移動部材が移動する際に生じる摩擦力変動と相関のある所定の診断パラメータを取得する。信号処理部が、所定の診断パラメータに係る信号から、第１所定周波数帯域の信号である第１診断用信号と、該第１所定周波数帯域よりも低い第２所定周波数帯域の信号である第２診断用信号とを抽出する。診断部が、第１診断用信号および第２診断用信号に基づいて運動案内装置の状態を診断する。【選択図】図１１
