Abstract

A method for an electric power tool includes providing a main current pulse (A) in a first direction driving a rotating shaft in a first direction to add torque to a joint; after providing the main current pulse (A), providing a current pulse (C) in an opposite direction to the first direction; immediately prior to providing the current pulse (C) in the opposite direction, providing a first pre-pulse current pulse (B) that is in the same direction as the current pulse (C) in the opposite direction and of a magnitude lower than the current pulse (C) in the opposite direction; and immediately prior to providing the main current pulse (A), providing a second pre-pulse current pulse (D) that is in the same direction as the main current pulse (A) and of a magnitude lower than the main current pulse.
