  • the CPU 7 inputs an output of the current sensor 9 through an A/D converter and an interface, which are not shown in the figure.
  • the CPU 7 obtains a rate of change of current in accordance with an output signal from the current sensor 9, and when the rate of change of current exceeds a set value, the CPU 7 judges occurrence of a broken-state of thread, and then stops supply of power to the spindle motor 2 of the corresponding spindle and also turns on the display portion 10a for displaying the broken-state of thread. Further, the spindle motor 2 is provided with a sensor (not shown) for detecting its rotational speed. In the case where the rotational speed of the spindle motor 2, which is detected by the sensor, largely deviates from a predetermined value, the CPU 7 judges that an abnormality has occurred, and then stops the spindle motor 2 and also turns on the display portion 10b for notifying abnormality.
