Abnormality monitoring apparatus for a mobile body drive control system

摘要

PROBLEM TO BE SOLVED: To reduce a abnormality detection delay time of a computer, to reduce an idle running time from abnormality detection to a deceleration stop operation start of a servomotor, and to reduce a shock at the time of an abnormal stop, in a servo system controlled by a computer (a CPU).;SOLUTION: The mobile body driving control system includes: a servo amplifier 12 driving the servomotor 11; a servo instruction part 13 outputting a speed instruction to the servo amplifier 12; and the CPU (the computer) 14 controlling the servo instruction part 13. The servo instruction part 13 includes a function as: an abnormality monitoring means 22 monitoring whether the CPU 14 malfunctions or not; and an abnormality deceleration stop means 23 changing the speed instruction output to the servo amplifier 12 such that the servomotor 11 is decelerated and stopped according to a predetermined deceleration stop profile, when the abnormality of the CPU 14 is detected by the abnormality monitoring means 22.;COPYRIGHT: (C)2011,JPO&INPIT
