    • An adapter includes a cord, a fitting portion, a voltage setting unit, and a fitting prevention mechanism. The cord is adapted to connect to a DC power source unit in order to receive DC voltage from the DC power source unit. The fitting portion is for insertion into the battery holding space of any one of a plurality of cordless power tools. The fitting portion receives the DC voltage received through the cord and supplies the DC voltage to a cordless power tool in which the fitting portion is properly inserted. The voltage setting unit is for setting voltage supplied through the fitting portion to the cordless power tool. The fitting prevention mechanism operates in linked association with operation of the voltage setting unit to prevent proper insertion of the fitting portion into a cordless power tool that has a rated voltage different from the voltage set by the voltage setting unit.
    • 适配器包括电线,配件部分,电压设定单元和配件防止机构。 线路适于连接到直流电源单元,以便从直流电源单元接收直流电压。 装配部分用于插入到多个无绳电动工具中的任何一个的电池容纳空间中。 装配部分接收通过绳索接收的直流电压,并将直流电压提供给无线电动工具,其中装配部分被正确插入。 电压设定单元用于将通过嵌合部供给的电压设定为无绳电动工具。 配合防止机构与电压设定单元的操作相关联地操作,以防止配件部分正确插入到具有与电压设定单元设定的电压不同的额定电压的无绳电动工具中。

    • A method of controlling a mounting unit having a shaft operated under servo control using a current driven actuator, comprises the steps of detecting interrruption of the servo control, and switching from a positioning control mode to a constant current control mode for supplying an constant amount of current to the shaft actuator to suspend the shaft. In an embodiment the method further includes engaging a gripping device, for holding the shaft, so as to keep the shaft from free-falling when interruption of the servo control is detected, and maintaining the constant current control mode at least until the gripping device grips the shaft. Still further, the current control mode optionally includes the steps of maintaining the supply of the constant amount of current for a predetermined period of time, and disengaging power supplied to the actuator after the predetermined period of time has elapsed.
    • 一种控制具有使用电流驱动致动器在伺服控制下操作的轴的安装单元的方法包括以下步骤:检测伺服控制的中断,以及从定位控制模式切换到恒定电流控制模式,以提供恒定量的 电流到轴致动器以悬挂轴。 在一个实施例中,该方法还包括接合用于保持轴的夹紧装置,以便在检测到伺服控制的中断时保持轴免于自由落下,并且保持恒定电流控制模式至少直到握持装置抓握 轴。 此外,电流控制模式可选地包括以下步骤:在预定时间段内保持恒定电流量的供应,并且在经过预定时间段之后分离供给到致动器的电力。
