Abstract

PURPOSE:To make it possible to smoothly return to the state before misoperation by resetting a timer at every fixed time while a microprocessor is in the normal operation and by initializing the performance of program for momentary misoperation. CONSTITUTION:In a device controlling a motor 5 by a microprocessor CPU1 performing a program by turns, the CPU puts out the count reset signals at every fixed time to give the interface 3 an instruction for putting out the current reference voltage Eo. Said Eo is amplified by a motor driving unit 4 using an inverter and such to control the motor 5. And while resetting the count by said count-resetting signals by means of counting the trunk output with a fixed period through the timer 2, the program performance is initialized by giving the offering signals to the CPU. Thereby for the momentary misoperation of the CPU it is possible to make to return to the state before misoperation.
