6. USING THE OPERATION PANEL (BASIC OPERATIONS) 6-2-3. Setting the zigzag width Set the zigzag width after selecting the pattern number. The zigzag width is defined as the distance between the leftmost needle drop point and the rightmost needle drop point. If the zigzag width is increased or reduced, the width of the sewing pattern is also increased or reduced by the same proportion. * The zigzag width will be automatically set to [0.0 ] only when the straight stitch has been selected as the sewing pattern. Zigzag width Zigzag width Zigzag width Zigzag width 1335M 1336M 2162M The currently-set zigzag width will appear in the main display (1). (For example, [5.0 ] represents 5.0 mm.) * When the zigzag width is being displayed, the zigzag width icon (2) will illuminate. Press the selection keys (3) to change the zigzag width. 3430M The standard setting range for the zigzag width is set to 0 - 8 mm at the factory. 3423M NOTE: • The zigzag width cannot be changed if the indicator is not illuminated, even when the zigzag width is being displayed in the main display . When changing the zigzag width, press the zigzag width/zigzag base line position key so that the indicator is illuminated, and then change the setting. • If the needle bar is at the needle up stop position, the needle bar will move to the sewing start position when the zigzag width is changed. If the needle bar is not at the needle up stop position, the needle bar will move to the sewing start position after it next moves to the needle up stop position. Sewing speed limits The sewing speed is limited by the amount of zigzag movement. Accordingly, the actual sewing speed may differ from the setting speed for the following sewing patterns as a result of the zigzag width setting. The speeds are controlled automatically as shown below. * For straight stitches and 3-step zigzag stitches, the sewing speed is not limited by the zigzag width setting. For plain zigzag and blind stitch Zigzag width 0-4 mm Sewing speed 5000 rpm 4.1-5.0 mm 4000 rpm 5.1-6.0 mm 3500 rpm 6.1-9.0 mm 3000 rpm 9.1-10.0 mm 2500 rpm For 2-step zigzag Zigzag width Sewing speed 0-8 mm 5000 rpm 8.1-10.0 mm 4000 rpm 31 Z-8550A, 8560A
