PURPOSE:To accelerate and to stably drive by detecting whether next incremental command is high or low speed, applying a temporary brake command pulse signal when the command is high speed to shorten the present total incremental time. CONSTITUTION:Command pulse signals P7, P8 from a constant time brake command pulse signal forming circuit 10 and command pulse signals P7', P8' from a temporary brake command pulse signal forming circuit 11 are input to a pulse selector 12. If the next incremental command (a) is high speed, the signals P7', P8' are immediately output during the decelerating tie Tb by the previous incremental command (a). Accordingly, the signals P7', P8' are previously input to the selector 12 to pass. Since the present increment is judged to be low or high speed by the incremental command given next, a stable operation can be performed. |
