Abstract

Eine multifunktionale Handwerkzeugmaschine mit einer zumindest teilweise axial schlagenden Werkzeugaufnahme (7), einer zwischen dieser und einem Elektromotor (6) im Kraftfluss angeordneten Sicherheitskupplung (8), einem handgeführten Gehäuse und einem ATC ("ANTI-TORQUE CONTROL")-Sicherheitsmodul (1) mit einem für eine Winkelbewegung empfindlichen Verdrehsensor (3), wobei das ATC-Sicherheitsmodul (1) mit einem Axialbewegungssensor (4) verbunden ist sowie das zugeordnete Steuerverfahren bei Überschreitung eines Axialgrenzwertes (13b) durch die Axialbewegung das binäre Steuersignal (5) unterdrückt.

Figure imgaf001
A multifunctional hand tool machine with an at least partially axially impacting tool holder (7), a safety clutch (8) arranged between the latter and an electric motor (6) in the power flow, a hand-held housing and an ATC ("ANTI-TORQUE CONTROL") safety module (1) with a rotational sensor sensitive to an angular movement (3), the ATC safety module (1) being connected to an axial motion sensor (4) and the associated control method suppressing the binary control signal (5) if an axial limit value (13b) is exceeded by the axial movement.
