Abstract: A method for recovery of a frictional brake device of an industrial device, the method including executing a recovery operation, the recovery operation including at least one movement of a second member of the industrial device relative to a first member of the industrial device, while engaging the brake device to apply braking energy to the movement; monitoring an actual value related to braking energy of the brake device during the recovery operation, the actual value being not related to speed of the movement; and stopping the recovery operation when the actual value reaches the at least one target value. An industrial device is also provided.

Abstract: A method for determining a dynamic friction torque of a frictional brake device of a joint of an industrial robot, the method including performing a disengaged brake movement of an electric motor of the joint while the brake device is disengaged; determining a disengaged brake torque value based on a torque reference of a control loop of the electric motor during the disengaged brake movement; performing an engaged brake movement of the electric motor while the brake device is engaged; determining an engaged brake torque value based on a torque reference of the control loop during the engaged brake movement; and determining the dynamic friction torque of the brake device based on a difference between the engaged brake torque value and the disengaged brake torque value. A control system and an industrial robot are also provided.
