<P>PROBLEM TO BE SOLVED: To provide a synchronous control method of a numerical control apparatus, which improves synchronous accuracy in synchronous control, when there is a difference between a control cycle of a position control part and a detection cycle of a position sensor. <P>SOLUTION: The numerical control apparatus 1 is provided with a position instruction output part 3 for outputting position instructions to a controlling shaft with regard to a plurality of motor controllers 2, 2' having independent position control parts 4, 4' every controlling shaft. In the synchronous control method of the numerical control apparatus for instructing the same position instruction to a plurality of the motor controllers at the same time and performing synchronous control between multiple shafts by independently performing position control using the motor controllers 2, 2', position control loop gains 9, 11 are corrected for delay time in the position control part of each controlling shaft on the basis of an expression (1). <P>COPYRIGHT: (C)2004,JPO |
