More Information
Summary:Provided is a drive control device capable of maintaining a drive control system in a safe state even on the occurrence of a malfunction in which a control processor cannot be reset in a normal manner or a malfunction which cannot be eliminated even if the control processor is reset. The control processor 11 has: an actuator control processing unit 113 for generating control signals for controlling a drive circuit 4 and an actuator 5 which are devices to be controlled; and a diagnostic processing unit 114 for performing a diagnosis of the actuator control processing unit. When the control processor 11 is operating normally, the diagnostic processing unit 114 periodically outputs a reset signal to a watchdog timer (WDT) 12. When this periodic reset signal is stopped, the WDT 12 continuously outputs a cutoff signal for cutting off the supply of the control signal from the control processor 11 to the devices to be controlled. 提供种驱动控制装置，即便当在控制处理器中发生控制处理器的重置未正常工作的工作异常或即使控制处理器进行了重置也未消除的工作异常时，也能够将驱动控制系统维持在安全状态。控制处理器
