Abstract

PURPOSE: To permit a spindle to be stably stopped at a predetermined position by using the output of a rotational position detector provided on the spindle and the actual rotational speed of the spindle to control the decelerating operation of the spindle in response to the inertia of load of the whole rotary system.
CONSTITUTION: Signals a, b generated by a rotary code disk 11a having a rotational position detector 11 of a spindle motor 1 built in itself and a spindle stopping command c are supplied to the input of a preset count control circuit 15 to control and preset deduction count pulses to first and second deduction counters 16, 31. Also, a speed error detecting circuit 25 detects the difference between the rotation command value of the spindle and actual rotational speed in the deceleration of the spindle to feed back it to a frequency dividing ratio controlling circuit 13 and change the frequency dividing ratio to control the rotational deceleration of the spindle due to the first deduction counter 16. Thus the decelerating operation is controlled in response to the inertia of load of the whole rotary system so that the spindle motor can be stably stopped at a predetermined position.
