if the current length pulse P3 is smaller than the high-speed length pulse P2, the high-speed counter outputs high-speed operation, and the color steel tile is cut at high speed; if the current length pulse P3 is greater than or equal to the high-speed length pulse P2, the high-speed counter outputs low-speed operation, and the color steel tile is cut at low speed; if the current length pulse P3 is greater than or equal to the set length pulse P1, the output of the high-speed counter stops running, and the color steel tile is stopped being cut;
