PURPOSE:To preserve a detector to a set position by a saved data with nonvolatile state, by producing a control signal through the comparison of a detection data from a position set detector and a saved data and forwarding or reversing a motor through the generation of a drive circuit signal with the control signal. CONSTITUTION:A position is arbitrarily set with a position detector 10 such as a potentiometer and a detection signal is outputted. The detection signal is digitized at an AD converter 11, inputted to a microcomputer 12, compared at an internal saved data, and a control signal of a specified voltage is outputted from a DIO2 terminal. A pulse signal is applied to a DC motor 14 from a terminal M1 of a pulse drive circuit 13, the DC motor 14 is forwarded and the potentiometer is turned to the objective direction. The saved data is converted to a set position of a position set detector with the feedback control. Thus, the study control of a car or the like using a microcomputer can be attained. |
