Abstract:
An average value of differences between command current values acquired at a plurality of timings when the motor is controlled at a rotation speed within a preset fixed range in a preset period and an average value of the command current values in the period is acquired, and the average value of the differences is accumulated in an order of the acquisition. When a difference between an accumulated value of the average values of the differences up to an N−1th time and an accumulated value of the average values of the differences up to an Nth time becomes greater than or equal to a preset value, and then become less than the preset value, and then again becomes greater than or equal to the preset value, a notification of an abnormality sign in the robot arm is transmitted.

Claim (Index 5):
An abnormality sign determination system of a robot arm comprising:\n a motor; a control unit configured to control the motor based on data indicating a command current value; an arm configured to operate based on a driving force of the motor, a connecting part connecting the motor to the arm and including a lubricant; and a server communicably connected to the robot arm, wherein the control unit acquires an average value of differences between the command current values acquired at a plurality of timings when the motor is controlled at a rotation speed within a preset fixed range in a preset period and an average value of the command current values in the period, and transmits data indicating the average value of the differences to the server, and the server accumulates the average values of the differences in an order in which the control unit acquires the average value of the differences, and when a difference between an accumulated value of the average values of the differences up to an N\u22121th time (N is a natural number of two or greater) and an accumulated value of the average values of the differences up to an Nth time becomes greater than or equal to a preset value, and then become less than the preset value, and then again becomes greater than or equal to the preset value, the server determines that there is an abnormality sign in the robot arm.
