A communication control system and method of communicating between a numerical control device and a plurality of servomotors, includes connecting the numerical control device to a plurality of servoamps of the plurality of servomotors in a loop configuration via bi-directional serial communication cables, splitting command data in the numerical control device, outputting a first portion of command data to one of the plurality of servoamps from the numerical control device in a counter-clockwise direction and a second portion of command data to one of the plurality of servoamps from the numerical control device in a clockwise direction, splitting feedback data in one of the plurality of servoamps, transmitting a first portion of feedback data to the numerical control device in a counter-clockwise direction from the one of plurality of servoamps in response to the first portion of command data, and transmitting a second portion of data to the numerical control device from the one of the plurality of servoamps in a clockwise direction in response to the second portion of command data, whereby splitting command data and feedback data and transmitting the split portion of data in clockwise and counter-clockwise directions to a servoamp reduces total transmission time.
