PROBLEM TO BE SOLVED: To attain quick and precise synchronization control between motors by a simple and versatile numerical controller system. SOLUTION: This numerical controller system is constituted of a numeral controller 1, a plurality of motor controllers 2, 3 and 4, and a communication device 15, and executes control for dividing a positional command in a received control command from a control period of positional command of the numerical controller 1 into a control period of positional command for the plurality of motor controllers 2, 3 and 4, by a positional command dividing part 20 in the communication device 15, and for transmitting the positional command to the plurality of motor controllers 2, 3 and 4. In the numerical controller system, the communication device 15 is provided with a synchronization control part 21 for computing a synchronization error of a shaft to be synchronization-corrected based on detection data of the plurality of motor controllers 2, 3 and 4, and for adding the synchronization error to the control period of positional command for the motor controllers 2, 3 and 4 of the shaft to be synchronization-corrected.
