1. A setting tool for driving fastening elements into a substrate, comprising a holder for holding a fastening element; a drive-in element for transferring a fastening element held in the holder into the substrate along a setting axis; a drive for driving the drive-in element toward the fastening element along the setting axis, wherein the drive comprises an electrical capacitor, an excitation coil, and an element arranged on the drive-in element and configured to provide a circulating current upon induction by an excitation magnetic field to create a force that repels the element from the excitation coil wherein, during rapid discharge of the electrical capacitor, current flows through the excitation coil and generates a magnetic field that accelerates the drive-in element toward the fastening element; the setting tool further comprising a control unit configured to control an amount of energy of the current flowing through the excitation coil during the rapid discharge of the electrical capacitor.
