A control method, for controlling a movable member 2() of an excavator, said control method including a step of: - providing an excavator including at least: - a movable member (2, 4, 6, 7, 8, 10) configured to hold a load when said excavator is in service, - an electric actuator (20, 20.4, 20.6) configured to actuate said movable member, said electric actuator comprising: i) an electric motor which is reversible and which is configured to apply a motor force (F21.20) on said electric actuator, and ii) a static brake configured to generate a brake force (F22.21) so as to brake said electric actuator, - a control unit configured to control, said electric motor and said static brake, and - a motion sensor unit configured to detect a motion of said electric actuator and to send motion signals to said control unit, wherein said static brake is configured to generate an upper threshold brake force and said electric motor is configured to generate an upper threshold motor force, said upper threshold brake force being inferior to said upper threshold motor force, and wherein said control method includes at least: - performing an immobilization step wherein said control unit controls said static brake to generate said upper threshold brake force, - performing a slippage detection step wherein said control unit checks said motion signals in order to detect whether said electric actuator is moving in a slippage direction despite said static brake generating said upper threshold brake force, - in case said control unit detects that said electric actuator is moving in said slippage direction, performing a motor energizing step wherein said control unit controls the power supply to said electric motor so that said electric motor generates a motor force substantially equal or superior to said upper threshold brake force in a direction opposite to said slippage direction, and - after start of said motor energizing step and in case said electric motor generates a non null motor force, performing a brake release step wherein said control unit releases at least partially said static brake. - providing an excavator including at least: - a movable member (2, 4, 6, 7, 8, 10) configured to hold a load when said excavator is in service, - an electric actuator (20, 20.4, 20.6) configured to actuate said movable member, said electric actuator comprising: i) an electric motor which is reversible and which is configured to apply a motor force (F21.20) on said electric actuator, and ii) a static brake configured to generate a brake force (F22.21) so as to brake said electric actuator, - a control unit configured to control, said electric motor and said static brake, and - a motion sensor unit configured to detect a motion of said electric actuator and to send motion signals to said control unit, - performing an immobilization step wherein said control unit controls said static brake to generate said upper threshold brake force, - performing a slippage detection step wherein said control unit checks said motion signals in order to detect whether said electric actuator is moving in a slippage direction despite said static brake generating said upper threshold brake force, - in case said control unit detects that said electric actuator is moving in said slippage direction, performing a motor energizing step wherein said control unit controls the power supply to said electric motor so that said electric motor generates a motor force substantially equal or superior to said upper threshold brake force in a direction opposite to said slippage direction, and - after start of said motor energizing step and in case said electric motor generates a non null motor force, performing a brake release step wherein said control unit releases at least partially said static brake.
