    • A motor drive control device is provided in which if any abnormality occurs in a drive control circuit, drive command signals the drive control circuit generates are interrupted at once, so that an AC motor can be stopped in safety. A monitor control circuit and drive command signal interruption circuit are provided to the drive control circuit that takes variable-speed control of the AC motor supplied with power from a DC drive power source via a semiconductor bridge circuit. If any abnormality occurs in the drive control circuit, the drive command signals the drive control circuit generates are interrupted at once. When starting operation, the drive control circuit and monitor control circuit cooperate with each other to conduct preliminary check as to whether or not the drive command signal interruption circuit operates normally, base on a predetermined time schedule, and stop the AC motor without fail if any abnormality occurs during operation.
    • 提供一种电动机驱动控制装置,其中如果在驱动控制电路中发生任何异常,驱动控制电路产生的驱动指令信号立即被中断,从而安全地停止AC电动机。 向驱动控制电路提供监视控制电路和驱动指令信号中断电路,该驱动控制电路经由半导体电路电路对从DC驱动电源供电的交流电动机进行变速控制。 如果驱动控制电路发生任何异常,则驱动控制电路产生的驱动指令信号立即中断。 启动时,驱动控制电路和监视控制电路相互协作,对驱动指令信号中断电路是否正常运行,基于规定的时间表进行初步检查,如果有任何异常,则停止交流电动机 操作过程中发生异常。

    • Respective positive terminal electric potentials of exhaust gas sensors are sequentially selectively inputted to an analog input terminal of a multi-channel AD converter through a multiplexer. An offset voltage is applied to respective negative terminals of the exhaust gas sensors. This offset voltage is inputted to another input terminal of the multi-channel AD converter. A microprocessor detects a generating voltage of the exhaust gas sensors by the difference between a digital converting value of the positive terminal electric potential and a digital converting value of the negative terminal electric potential. The microprocessor also individually judges that each of the digital converting values is excessively small and excessively large. Thus, the microprocessor judges the existence of ground, sky short circuit and disconnection abnormalities of the negative terminal and the positive terminal.
    • 废气传感器的正极端子电位通过多路复用器依次选择性地输入到多通道AD转换器的模拟输入端。 对排气传感器的各负极施加偏移电压。 该偏移电压被输入到多通道AD转换器的另一个输入端。 微处理器通过正极端子电位的数字转换值与负极端子电位的数字转换值之差来检测废气传感器的发电电压。 微处理器还单独地判断每个数字转换值过小和过大。 因此,微处理器判断负极和正极端子的接地,天线短路和断线异常的存在。
