Title:
MALFUNCTION DETECTION/DIAGNOSIS METHOD AND DEVICE FOR SERVO CONTROL SYSTEM, AND AUTOMATIC RECTIFICATION METHOD AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP3970829
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high-reliability servo control system by facilitating cause investigation in trouble occurrence by generating a parameter abnormality alarm when a detector type designated by a parameter is different from that of a detector actually connected.
SOLUTION: Transmission-side connection states of a plurality of receiving circuits for detectors are detected to automatically determine the type number of the detector actually connected in turning power on, and when the detector type designated by a parameter is different from that of the detector actually connected, the parameter abnormality alarm is generated.
