Abstract

PURPOSE:To detect the stepping out of a pulse motor for elevating or lowering of a fuel rod and the like as its load by forcedly accelerating or decelerating the motor at predetermined period or predetermined pulse interval and varying the speed pattern at the time of gravity fall for determination whether the rotation pulse and the position signal match each other. CONSTITUTION:A drive circuit 20 of a step motor 1 rotates the motor corresponding the normal or reverse turn instruction of terminals 51 and 52. The signal of a position detector 21 is added to a counter 24 via an AND gate 28 while the output signals of the counter 23 and 24 are given to a deviation operating circuit 25 which performs a predetermined operation taking in a signal from a timing pulse generator 26 to determine the stepping out of the pulse motor.
