26 5. Detailed explanation of selection of functions Selection of the soft-start function (Function setting No. ) The needle thread may fail to interlace with the bobbin thread at the start of sewing when the stitching pitch (stitch length) is small or a thick needle is used. To solve such problem, this function (called soft-start ) is used to limit the sewing speed, thereby assuring successful formation of the starting stitches. 0 : The function is not selected. 0 to 9 : The number of stitches to be sewn under the soft-start mode. The sewing speed limited by the soft-start function can be changed. (Function setting No. 37) Data setting range to MAX rpm <50 rpm> 2 Material end sensor (ED : optional) function (Function setting No. 2 to 4) This function is possible when the material end sensor (ED) is attached. As for the details, refer to the instruction manual for the material end sensor. ENGLISH (Caution) Setting will be invalid when the material end sensor is not attached, or CP-60 is connected. 3 Flicker reducing function (Function setting No. 5) The function reduces flickering of the hand lamp at the start of sewing. The higher the set value increases, the more effective the function will work. Setting range 0 to 8 0 : Flicker reducing function does not work. 5 0 to 8 : Flickering is effectively reduced. (Caution) The more effective the flicker reducing function works (the more the set value is made), the lower the start-up speed of the sewing machine will become. 4 Bobbin thread counting function (Function setting No. 6) When the control panel (CP-60) is used, the function subtracts from the predetermined value and indicates the used amount of bobbin thread. For the details, refer to the instruction manual for the control panel. (Caution) If 0 is set, the LCD indication on the control panel will go out and the bobbin thread counting function will be invalid. 5 Thread trimming prohibiting function (Function setting No. 9) This function turns OFF thread trimming solenoid output and wiper solenoid output when thread trimming is actuated. [If the control panel (CP-60) is used with the sewing machine, this function will work in accordance with the function setting on the control panel.] By this function, separate sewing material can be spliced and sewn without trimming thread. 0 : off Thread trimming is operative. (thread can be trimmed). 9 0 : on Thread trimming is inoperative. (thread can not be trimmed). 6 Setting of the needle bar stop position when the sewing machine stops (Function setting No. 0) The position of the needle bar when the pedal is in its neutral position is specified. 0 : Down The needle bar stops in the lowest position of its stroke. 0 0 : Up The needle bar stops in the highest position of its stroke. (Caution) If the stop position of the needle bar is set to the highest position, the thread trimming action will be taken after the needle bar comes down once to the lowest position. 24

27 7 Sound of click of the key switch mounted on the PSC box (Function setting No. ) This function selects whether the sound is effective or ineffective when operating the four key switches mounted on the PSC box. 0 : off The sound of click is ineffective. : on The sound of click is effective. 8 Optional switch function selection (Function setting No. 2) : It is used only when it is combined with the machine head provided with the optional switch. Functions to be assigned to the optional switch can be selected from the following functions. 0 : No function (Standard setting) 2 0 : Needle up / down compensating stitching : Every time the switch is pressed, normal feed stitching by half stitch is performed. (Same operation as that of up / down compensating stitching switch on the panel.) 2 : Back compensating stitching : Reverse feed stitching is performed at low speed while the switch is held pressing. (It is effective only when constant dimension sewing pattern is selected with the CP-60.) 3 : Function of canceling once reverse feed stitching at the end of sewing : By depressing the back part of the pedal after pressing the switch, operation of reverse feed stitching is canceled once. 4 : Thread trimming function : This function is actuated as the thread trimming switch. 5 : Presser foot lifting function : This function is actuated as the foot lifter switch. 6 : One stitch compensating stitching : Every time the switch is pressed, one stitch stitching operation is executed. 7 : Function of simultaneously canceling reverse feed stitching at the start and end of sewing : By operating the optional switch, ineffective/effective can be alternately changed over. 8 : Presser foot lifting function when pedal is neutral : Every time the switch is pressed, the function whether automatically lifting the presser foot when the pedal is neutral or not can be selected. (Note) Indication of reverse feed stitching at the start and end of sewing on the operation panel is the same even when the function is canceled. So, be careful. 9 Sewing counting function (Function setting No. 4) The function counts up every time thread trimming is completed and counts the number of completion of the sewing process. This can be realized together with the CP-60 control panel. Refer to the explanation of the control panel. : on Sewing counting function is operative. 4 0 : off Sewing counting function is inoperative. (Indication on the CP-60 contorl panel will go out as well.) (Caution) Setting will be invalid when the material end sensor is not attached, or CP-60 control panel is connected.!0 Neutral automatic presser lifting function (with AK device only) (Functionsetting No. 2) This function can automatically lift the presser foot when the pedal is in the neutral position. Automatic lifting time of the pedal depends on the automatic lifting time after thread trimming and when the presser foot is automatically lowered, it is automatically lifted at the second neutral position after it has come off the neutral position once. 0 : off Function of neutral automatic presser lifting is not operative. 2 0 : on Selection of function of neutral automatic presser lifting 25
