ABSTRACT:
The present invention relates to a motor control method and apparatus therefor in a numerical control system of using an exclusive computer equipped with a built-in program, where an administration computer calculates an initial value corresponding to a displacement amount to be driven by each axis of a motor, and where a motor control computer controls a driving of the motor in accordance with the displacement amount of the motor corresponding to the initial value calculated from the administration computer, thereby enabling to perform the numerical control function by sharing the same between computers, so that an execution velocity needed for the numerical control can be reduced and an adaptive control can be swiftly performed to meet instantly-changing situations as well.
