<p>PURPOSE:To attain a high-speed operation by discriminating whether an NC processing program from a host computer is NC processing data to be processed by an NC program analyzing part or NC processing data to servo control parts and distributing it directly to the shaft servo control part when it is the NC processing data to the servo control parts. CONSTITUTION:A communication control part 3 discriminates whether NC processing data 12 transmitted from a host computer 1 through a communication line are NC processing data 13 to be processed by an NC program analyzing part 4 or NC processing data 17 to the servo control parts and transfers them to a servo position command distribution part 16 when they are the NC processing data to shaft control parts 6-8. The servo position command distributing part 16 transfers the NC processing data 17 from the communication control part 3, namely, a servo position command to the servo control parts 6-8 synchronously. Thus, the high-speed operation of a servo shaft is attained without being restricted by the processing time of the NC program analyzing part 4 and the 1-block data transfer time to an interpolation control part 5.</p> |
