Abstract
All correction data is stored in the main memory of a numerical controller in advance. Of all correction data, the minimum data required for correction is transferred, for each interpolation cycle, to a built-in memory of a peripheral control LSI included in a servo control unit. A servo control processor performs repetitive control using the data transferred to the memory.
Claims6
A servo motor control system including a numerical control processor and a servo control processor, the numerical control processor creating an instruction for controlling a servo motor and outputting the created instruction to the servo control processor, the servo control processor controlling the servo motor based on the output instruction, the servo motor control system comprising:
- a first memory to which the servo control processor configured to refer;
- a second memory to which the numerical control processor configured to refer;
- a memory transfer means for transferring data from the second memory to the first memory;
- and
- a timing notification means for notifying the memory transfer means of a timing of memory transfer,
- wherein, when the timing notification means instructs the memory transfer means to transfer memory, the memory transfer means transfers data from the second memory to the first memory and the servo control processor controls the servo motor using the data transferred from the second memory to the first memory.
