Title:
MOVING SPEED COMMAND GENERATION METHOD AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP3618558
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress a sudden change of moving speed commands in an overlap part based on a plurality of moving quantity commands by dividing the respective moving quantity commands into a plurality of speed commands being speed distribution changing at every prescribed acceleration on a time sequence.
SOLUTION: When a moving quantity command L and a speed command F are inputted, a primary division means 1 divides the moving quantity command L with the speed command F as a unit and sequentially outputs primary division speed ΔL based on the respective moving quantity commands. A secondary division means 3 divides the primary division speed ΔL with unit speed A stored in a unit speed storage means 2 as the unit and sequentially outputs secondary division speed Δ2 based on respective primary division speeds ΔL. Respective secondary division speeds ΔL2 are accumulated/added in fine periods for the number of secondary divisions with a speed memory pointed by an iterator storage means 5 as a first one. An output means 6 outputs the accumulation speed ΔM of the speed memory, at which pointing by the iterator storage means 5 passes, as the moving speed commands for every fine interval.
