振幅位相でなくて、かつ刺繍枠が出ている場合は、表
示装置に「U/Dを押して下さい」を表示する。If it is not the amplitude and phase and the embroidery frame is displayed, "Press U / D" is displayed on the display device.
U/Dスイッチを押したかどうかチェックして押してい
なければ初めにもどり、押していれば「U/Dを押して下
さい」の表示を消去して、ミシン上軸を回転させて針を
上に上げる。Check whether the U / D switch has been pressed and return to the beginning if it has not been pressed. If it has been pressed, clear the display of "Please press U / D" and rotate the upper shaft of the sewing machine to raise the needle.
再び振幅位相をチェックして振幅位相ならば全ステッ
ピングモータの初期セットを行い、振幅位相でない場合
