Abstract

Die Erfindung betrifft ein Verfahren und eine Steuerung (22) für eine elektrische Hand-Werkzeugmaschine (10) , die einen Anschluss für eine eine Anzahl wiederaufladbarer elektrischer Speicherzellen (21) aufweisende Stromspeichereinrichtung (20) aufweist, wobei die Steuerung (22) Steuermittel (36) zum Steuern eines Antriebsmotors (11) der Hand-Werkzeugmaschine (10) aufweist, wobei die Steuerung (22) Detektionsmittel (35) zur Ermittlung eines Unterspannungswertes (Umin) und/oder eines Dauerstromwertes (Imax) der Stromspeichereinrichtung (20) aufweist, wobei der Stromspeichereinrichtung (20) bis zum Erreichen des Unterspannungswerts (Umin) elektrische Energie entnehmbar ist und wobei der Dauerstromwert (Imax) einen maximalen Strom repräsentiert, der der Stromspeichereinrichtung (20) dauerhaft entnehmbar ist, und wobei die Steuermittel (36) zum Steuern und/oder Regeln des Antriebsmotors (11) anhand des Unterspannungswertes (Umin) und/oder des Dauerstromwertes (Imax) ausgestaltet sind. The invention relates to a method and a controller (22) for an electric hand tool machine (10) having a terminal for one of a number of rechargeable electrical storage cells (21) current memory means (20), wherein the controller (22) control means (36 ), for controlling a drive motor (11) of the hand tool machine (10) wherein the controller (22) detecting means (35) for determining a lower voltage value (Umin) and / or a constant current value (Imax) of said power storage device (20), wherein the electricity storage unit (20) until it reaches the lower voltage value (Umin) is removable electrical energy and wherein the continuous current value (Imax) represents a maximum current which is permanently removed, the current storage means (20), and wherein said control means (36) for controlling and / or regulating the drive motor (11) based on the lower voltage value (Umin) and / or of the continuous current value (Imax) are designed.
