Abstract

The invention relates to a method for commanding the brakes (F1, F2, F3) of the motors (M1, M2, M3) of a multi-axis robot (R1), comprising:

a robot arm (B) comprising at least two degrees of freedom each associated with an electric motor (M1, M2, M3), a sensor (C1, C2, C3) for measuring movement information, and a brake (F1, F2, F3),an interfacing unit (4) of the brakes (F1-F3) able to control the supply of electricity to the brakes (F1-F3),a central processing unit (2),variable drives (V1, V2, V3) having a torque off function of the motors (M1-M3),a security system (4, 5),the method comprising the following successive steps:6a) selecting a motor (M1-M3),6b) activating an electric braking function using the selected motor (M1-M3),6c) opening the brake (F1-F3),6d) comparing the movement information delivered by the sensor (C1-C3) to a threshold,6e) closing the brake (F1-F3) when the movement information exceeds the threshold.
