Title:
運動案内装置の状態診断装置
Document Type and Number:
Japanese Patent JP6947474
Kind Code:
B2
Abstract:
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
