ends, sewing stops and the sewing speed becomes the start backtacking
(constant) speed
1: When the treadle is returned to the neutral position, start backtacking can
be stopped before it is finished, and the speed during start backtacking
becomes the speed corresponding to the treadle depression amount (low
