Abstract

12 PURPOSE:To simplify a circuit configuration and to reduce a cost, by storing in advance a loading program in a subporcessor SPC for sharing a load of a main processor MPC, and executing the LPG by the SPC. CONSTITUTION:LPG is stored in advance in a vacant area of an ROM61 of an SPC60 for sharing a load of an MPC10. When an electric power supply of a numerical control device is turned on, a switching circuit 80 is switched to the side of the SPC60, the LPG in the ROM61 is executed by the SPC60, and a control program stored in advance in a nonvolatile memory 30 is transferred to an RAM40, by which loading is executed. In this way, an ROM to be exclusively used for the LPG becomes unnecessary, the circuit configuration is simplified, and the hardware cost is reduced.
