Abstract
PURPOSE:To improve the work precision and to absorb the variance of work precision among individual machines with respect to high speed positioning work by dynamically rewriting an optimum servo parameter constant value by a work program (pitch). CONSTITUTION:One-block components of data are read out from a work command (program) storage part 1, and preprocessed date 6 is generated in a preprocessing part 3 by this read-out block data and is transferred to an interpolator 4. A pitch P of the movement command quantity, which indicates the extent of movement of the table of a punch press, in block data is compared with pitch range parameter values in a parameter register part 2 to obtain a pertinent pitch range, and a corresponding servo parameter constant value 8 is selected, and the servo constant of a servo processor is rewritten with the selected servo parameter constant value 8 before a command pulse train 7 is outputted to the servo processor 5 from the interpolator 4. Thus, the variance of work precision due to the positioning pitch is uniformized.
