Servo control device, spindle failure detection method using servo control device, and non-transitory computer readable medium encoded with computer program

摘要: To provide an arrangement capable of detecting spindle failure in a machine tool using existing servo control device, without providing separate external sensors, analysis device or the like. A (22), which detects including spindle, feed shaft, and positioning servomotor that is installed to shaft for deciding position includes: feedback acquisition unit (222) acquires signal servomotor; analysis/detection 226 analyzes acquired detect spindle.
