<p>A numerical value control device synchronization control method for improving a synchronization accuracy of synchronization control when the position control section has a different control cycle and the position detector has a different detection cycle. In the synchronization control method of a numerical value control device (1) having a position instruction output section (3) for outputting a position instruction of the control axes to a plurality of motor control devices (2, 2’) having position control sections (4, 4’) independent for each of the control axes, the same position instruction is simultaneously instructed to the plurality of motor control devices (2, 2’), so that they are position-controlled independently from each other so as to perform inter-axes synchronization control and position control loop gains (9, 11) are corrected, considering the delay of the position control sections (4, 4’) of the respective control axes.</p> |
