A method for disconnecting a manual control unit of a multi-axis robot, the manual control unit including: - an emergency stop button, - a dead man contactor, - a connecting cord for connecting the manual control unit to a robot controller, the cord including: - an input power line (eAU1, eAU2) and output power line (sAU1, sAU2) for each of the two cabling circuits (AU1, AU2) of the emergency stop button, and - an input power line (eHM1, eHM2) and output power line (sHM1, sHM2) for each of the two cabling circuits (HM1, HM2) of the dead man contactor, the robot controller including: - a central processing unit able to execute programs for commanding the robot arm, and - a safety controller able to test the two cabling circuits (AU1, AU2) of the emergency stop button and the two cabling circuits (HM1, HM2) of the dead man contactor, and trigger an emergency stop of the robot arm, characterized in that it comprises successive steps, in which: - a) an operator makes a request to disconnect the manual control unit, - b) during a predetermined length of time started upon the disconnection request, the safety controller suspends the control of the two electrical cabling circuits (AU1, AU2) of the emergency stop button and of the two cabling circuits (HM1, HM2) of the dead man contactor so as not to trigger the emergency stop, - c) at the end of the predetermined length of time, the safety controller does not trigger an emergency stop of the robot arm if and only if, on the one hand, only one of the two cabling circuits (AU1, AU2) of the emergency stop button is open and, on the other hand, only one of the two cabling circuits (HM1, HM2) of the dead man contactor is open. - an emergency stop button, - a dead man contactor, - a connecting cord for connecting the manual control unit to a robot controller, the cord including: - an input power line (eAU1, eAU2) and output power line (sAU1, sAU2) for each of the two cabling circuits (AU1, AU2) of the emergency stop button, and - an input power line (eHM1, eHM2) and output power line (sHM1, sHM2) for each of the two cabling circuits (HM1, HM2) of the dead man contactor, - an input power line (eAU1, eAU2) and output power line (sAU1, sAU2) for each of the two cabling circuits (AU1, AU2) of the emergency stop button, and - an input power line (eHM1, eHM2) and output power line (sHM1, sHM2) for each of the two cabling circuits (HM1, HM2) of the dead man contactor, - a central processing unit able to execute programs for commanding the robot arm, and - a safety controller able to test the two cabling circuits (AU1, AU2) of the emergency stop button and the two cabling circuits (HM1, HM2) of the dead man contactor, and trigger an emergency stop of the robot arm, characterized in that it comprises successive steps, in which: - a) an operator makes a request to disconnect the manual control unit, - b) during a predetermined length of time started upon the disconnection request, the safety controller suspends the control of the two electrical cabling circuits (AU1, AU2) of the emergency stop button and of the two cabling circuits (HM1, HM2) of the dead man contactor so as not to trigger the emergency stop, - c) at the end of the predetermined length of time, the safety controller does not trigger an emergency stop of the robot arm if and only if, on the one hand, only one of the two cabling circuits (AU1, AU2) of the emergency stop button is open and, on the other hand, only one of the two cabling circuits (HM1, HM2) of the dead man contactor is open. - a) an operator makes a request to disconnect the manual control unit, - b) during a predetermined length of time started upon the disconnection request, the safety controller suspends the control of the two electrical cabling circuits (AU1, AU2) of the emergency stop button and of the two cabling circuits (HM1, HM2) of the dead man contactor so as not to trigger the emergency stop, - c) at the end of the predetermined length of time, the safety controller does not trigger an emergency stop of the robot arm if and only if, on the one hand, only one of the two cabling circuits (AU1, AU2) of the emergency stop button is open and, on the other hand, only one of the two cabling circuits (HM1, HM2) of the dead man contactor is open.
