PROBLEM TO BE SOLVED: To build an inexpensive motion control system that unnecessitates a real time OS, a network capable of performing high-speed synchronous communication, and an exclusive NC board, and uses a PC operated at low real time. SOLUTION: The PC 10 is provided with a position command buffer 112 storing a plurality of position commands, and a position command request receiving means 104 for extracting the position commands from the position command buffer 112 when receiving a request of a servo drive 20. The servo drive 20 has a position command request means 203 for periodically outputting the position command request to the PC 10. COPYRIGHT: (C)2007,JPO&INPIT
