WIPO Patent Application WO/2017/216938
Kind Code:
A1
Abstract:
This servo control diagnostic system (10) comprises: an integrator (102) for integrating the rotation speed of a servomotor (2) which drives a machine end (3) and outputting the result as motor end position data; a first diagnostic unit (204) which compares a degree of change of a value of machine end position data which is position data of the machine end (3) from a time at which a trigger has occurred with a predetermined position data threshold (207); and a second diagnostic unit (205) which compares a degree of change of a motor end position data value from the time at which the trigger has occurred with the position data threshold (207).
