Abstract

PURPOSE:To ensure the accurate and easy control of a motor before and after the positioning of an object to be driven, by controlling the rotation of the motor based on the output of a storage circuit that stores the state of rotation of the motor. CONSTITUTION:The output voltage of a tachogenerator 14 attached to a motor 2 is connected to the input side of a comparator COM 13. The voltage polarity of the generator 14 is always coincident with the rotating direction of the motor 2, and accordingly this polarity can be set coincident with the rotating direction of the motor 2 before the positioning by using the voltage of the generator 14 as a speed command and regardless of a speed command 4, a forward turn command 3 and a backward turn command 12. The rotating direction of the motor 2 in case a positioning command is given immediately after the power source is applied is decided by applying the initial reset pulse 17 to the comparator COM13 through SW4(15) or SW5(16).
