摘要:
The invention relates to a control method for a handheld power tool (1), which has a motor (5) for rotationally driving a tool holder (2) about a working axis (12), which control method comprises the following steps: sensing a rotational motion of the handheld power tool (1) about the working axis (12); sensing a rotational or pivoting motion about a transverse axis (18) extending transversely to the working axis (12); triggering a protective function for reducing the torque output of the motor (5) if the rotational motion about the working axis (12) exceeds a limit value, and suppressing the protective function if the rotational or pivoting motion about the transverse axis (18) is greater than a threshold value.
摘要:
The control method for a hammer drill (1) provides the following steps. In basic operation, the motor (5) rotates at an operating speed for drill bit operation to rotatingly drive the tool receptacle (2) and to drive the striking mechanism (6) with a nominal striking power. The torque coupling (21) is monitored by a sensor (26). If the torque coupling (21) is released, then the striking power of the striking mechanism (6) is reduced to below 10% of the nominal strike power during a release of the torque coupling (21), and the torque coupling (21) is rotatingly driven. When the release of the torque coupling (21) ends, the striking power of the striking mechanism (6) is increased to the nominal striking power and the torque coupling (21) is driven at the operating speed for drill bit operation.
