    • Control data is efficiently serially transferred to a motor drive device (12) for driving a motor without involving the CPU. Specific memory addresses are allocated to data buffers (BF1 - BFn). An address decoder (42) decodes a memory address output to an address bus (30) and applies a write enable signal to the corresponding data buffer to write data to the data buffer by DMA transfer. When data is written to any data buffer, a sequencer circuit (44) stores control data compiled based on data in data buffers BF1 - BFn in a shift register 46, and serially transfers the control data to a serial transfer line (20) synchronized to a clock.
    • 控制数据被有效地顺序地传送到用于驱动马达而不涉及CPU的马达驱动装置(12)。 具体的存储器地址被分配给数据缓冲器(BF1-BFn)。 地址解码器(42)对输出到地址总线(30)的存储器地址进行解码,并将写使能信号施加到对应的数据缓冲器,以通过DMA传输将数据写入数据缓冲器。 当数据被写入任何数据缓冲器时,定序器电路(44)将基于数据编码的控制数据存储在移位寄存器46中的数据缓冲器BF1-BFn中,并且将控制数据串行地传送到串行传输线(20) 一个钟。

    • A high-speed memory (4) is constructed so that it is provided with at least a first data-storage region (4a) which is accessed by a processor (1) and a second data-storage region (4b) into which data in a low-speed memory (5). is transferred and stored. The processor (1) reads data out of the first data-storage region (4a) of the high-speed memory (4), then transfers the data in the second data-storage region (4b) of the high-speed memory (4) into the first data-storage region (4a), and also accesses the low-speed memory (5) to transfer data therein into the second data-storage region (4b) of the high-speed memory, so that the processor can continuously read out data regardless of any access to the low-speed memory.

    • Every time the total number of rotations of a spindle motor (11) reaches a value set in a positional data table (T), a CPU (22) reads out the movement positions of a work and a tool at the reached total number of rotations and the movement positions at the total number of rotations to be reached next from a positional data storage section (25) and reads out the moving speed characteristics between the reached total number of rotations and the next total number of rotations to be reached from a moving speed characteristics storage section (27) according to an auxiliary operation command on the positional data table (T). Subsequently, the CPU (22) divides the interval between as a starting point, the time of the reached total number of rotations and, as a finish point, the time of the next total number of rotations with specified timings and defines the movement positions of the work and the tool at the division timings based on the read movement positions of the work and the tool and the read moving speed characteristics.
