SPEED CONTROL METHOD FOR STEPPING MOTOR, WEAVING CONTROL METHOD FOR WELDER, AND METAL TO BE WELDED

PROBLEM TO BE SOLVED: To provide a speed control method for a stepping motor which realizes large acceleration and deceleration without a step out. SOLUTION: Values a1-a4 in buffers are output pulse numbers in a long period computed last time and are integers, and values b1-b4 in buffers are output...
