Abstract
Official abstract text for this publication.
A robot control system includes an operation command output unit which outputs an operation command of a motor, a position detection unit which is provided on the motor to detect the position of a control shaft, a stop signal output unit which outputs a stop signal to stop the robot when the speed of the control shaft acquired from the position detection unit exceeds a speed threshold value, and an operation command interruption unit which interrupts the operation command outputted from the operation command output unit when the stop signal is outputted.
First claim
Opening claim text (preview).
What is claimed is: 1 . A robot control system which controls a robot having at least one control shaft driven by a motor, comprising an operation command output unit which outputs an operation command of the motor; a position detection unit which is provided on the motor to detect the position of the control shaft; a stop signal output unit which outputs a stop signal to stop the robot when the speed of the control shaft acquired from the position detection unit exceeds a speed threshold value; and an operation command interruption unit which interrupts the operation command outputted from the operation command output unit when the stop signal is outputted. 2 . A robot control system according to claim 1 , further comprising a reference position storage unit which stores therein the position of the control shaft detected by the position detection unit at the time when the stop signal is outputted as a reference signal; and a power interruption unit which interrupts a power supply to the robot when a deviation between the position of the control shaft detected by the position detection unit and the reference position stored in the reference position storage unit exceeds a deviation threshold value while the stop signal is outputted. 3 . A robot control system according to claim 2 , wherein when the operation command is outputted from the operation command output unit while the stop signal is outputted, the operation command interruption unit commands the power interruption unit to interrupt the power supply to the robot.
