ピンドル制御装置。A first motor for rotating the spindle for turning, a first motor drive circuit for driving the first motor, a second motor for positioning the spindle, and a second motor drive circuit for driving the first motor. In a spindle control device for a machine mechanism, the device includes a second motor drive circuit for driving the motor, and a clutch for selectively connecting the first motor and the second motor to the spindle. a pulse generator that is permanently connected and generates a number of feedback pulses proportional to the rotational angle of the spindle and a specific rotational position pulse; and a pulse generator that is reset by the specific rotational position pulse from the pulse generator and that counts the feedback pulses to counting means for detecting the current rotational angular position of the spindle; storage means for storing the positioning command value of the spindle; a motor, and adds the difference amount between the positioning command value stored in the storage means and the current rotational angular position according to the count contents of the counting means to the second motor drive circuit, and performs positioning by the second motor. 1. A spindle control device for a machine tool, comprising: means for performing control.
