The number of intersects measuring means measures the number of times when the d-q coordinate currents and the first predetermined value intersect each other in a predetermined time. The number of times of matching measuring means measures the number of times when the number of intersects measured by the number of intersects measuring means is matched with a second predetermined value. The number of times of matching comparing means compares the number of times of matching measured by the number of times of matching measuring means with a third predetermined value. If the number of times of matching becomes equal to or exceeds the third predetermined value, the number of times of matching comparing means detects step-out.  <P>COPYRIGHT: (C)2004,JPO
