    • A controlled method of operating a programmable controller containing a program storage section including memory means in which a plurality of programs are stored with each program having a master reset flag and corresponding to a stage consisting of one or more control programs for performing control functions when the control programs in each stage are executed. In accordance with the method, a series of programs each corresponding to a stage is read out from the memory means with the control programs of each stage executed when both a master reset flag for a stage, which is reset in initialization, and a stage status corresponding to each of the read out stages meet a predetermined relationship. When executing a control program, a status for a subsequent macro-block is set or reset. The macro-block consists of a plurality of stages. When the status of the macro-block is set, the master reset flag for a stage is subsequently reset at the beginning of the macro-block. When the status of the macro-block is reset, the master reset flag for a stage is subsequently set at the beginning of the macro-block. A plurality of stages included in the macro-block are then executed provided that the status of the macro-block is set and the master reset flag for a stage is reset.

    • When stopping operation of an electric power steering apparatus, a motor relay is kept in an on-state even after a power supply relay is in an off-state. A drive control portion sets a target value of a d-axis current to a value other than zero and sets a target value of a q-axis current to zero, and performs a processing same as that at the time of rotating a motor. MOS-FETs contained in a motor driving circuit are controlled such that each of driving currents of the two phases or more is not zero and the brushless motor does not rotate even supplied with these driving currents. Electric charge accumulated in a capacitor is discharged via the MOS-FETs each in an on-state, a motor relay and the windings of the brushless motor. The electric charge accumulated in the capacitor may be discharged via the excitation coil of the motor relay.
    • 在停止电动转向装置的动作时,即使电源继电器处于关闭状态,电动机继电器也保持接通状态。 驱动控制部将d轴电流的目标值设定为零以外的值,将q轴电流的目标值设定为零,并进行与电动机旋转时相同的处理。 控制电动机驱动电路中包含的MOS-FET,使得两相或更多相的驱动电流不为零,并且无刷电动机即使被这些驱动电流提供也不旋转。 电容器中累积的电荷通过MOS-FET各自在导通状态,电动机继电器和无刷电动机的绕组中放电。 蓄积在电容器中的电荷可以通过电动机继电器的励磁线圈放电。
