Abstract: This method relates to the disconnection of a manual control unit of a multi-axis robot, including a connecting cord for connecting the unit to a controller. The cord includes an input power line and output power line for each of the two cabling circuits of an emergency stop button, and an input power line and output power line for each of the two cabling circuits of a dead man contactor. The method comprises successive steps, in which: a) an operator makes a request to disconnect the unit, b) during a predetermined length of time, the safety controller does not trigger an emergency stop based on the control of the electrical cabling circuits, c) at the end of the predetermined length of time, the safety controller does not trigger an emergency stop if and only if, on the one hand, only one of the two cabling circuits of the emergency stop button is open and, on the other hand, only one of the two cabling circuits of the dead man contactor is open.

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.
