@. SET-UP

Install the motor unit to the control box following the instructions below.

Supply voltage Single phase 100 to 120V / 3-phase 200 to 240V Single phase 200 to 240V

Frequency 50 Hz / 60 Hz 50 Hz / 60 Hz

Operating environment Temperature : 0 to 40˚C Temperature : 0 to 40˚C

Humidity : 90% or less Humidity : 90% or less

Power consumption 425VA 425VA

1. Installing the motor unit

Install the motor unit on the table with the fitting bolt

asm. supplied with the unit as accessories.

At this time, insert the nuts and washers supplied with

the unit as accessories as shown in the figure so that

the motor unit can be securely fixed on the table.

1) Press three bolts 1 supplied with the unit as

accessories into the motor hanging bolt hole in the

table and fix them.

2) Temporarily tighten convex washer, spring washer

and nut on the side where two bolts are attached.

3) Hang the motor unit to the washer which has been

temporarily tightened, and attach convex washer,

spring washer and nut to the other bolt on the

opposite side.

4) After adjusting the installing position of the motor,

securely tighten the respective nuts.

2. Installing the control box

1) Loosen four screws 2 supplied with the motor unit

as accessories, tighten screws 2 after hanging

control box unit 3 to the screws, and fix control

box unit 3.

(Caution) 1. Indication of the power consumption is the mean power consumption when LU-1520N-

7 is mounted in accordance with the operating conditions JUKI specifies.The power

consumption changes in accordance with the operating conditions and the mounted

machine head. So, be careful.

2. Instantaneous maximum power consumption may become 1.5 times or more than the

mean power consumption.

− 2 −

15mm (9.8N)

3. Installing the belt

1) The belt distance, between sewing machine pulley

and motor pulley, must be parallel.

2) The belt tension should be adjusted by turning the

tension adjust nuts to change height of the motor,

so that the belt sinks down by about 15 mm (9.8N)

when it is depressed by band at the center of the

belt span.

If the belt tension is not tight, speed is unstable at

low-speed or medium-speed operation, and the

needle will not stop exactly in position.

4. Adjusting the pulley cover

1) After adjusting the belt tension, adjust the pulley

cover 1 so that the clearances between the belt

and the pulley cover 1, a and b should be the

same.

2) After the completion of adjustment, tighten screws

2 located on the side of pulley cover 1 and

securely fix the pulley cover 1 so that it does not

slip out of position.

1) Attaching hole for the protecting pin

To attach protecting pin 1, select either attaching

hole A or attaching hole B in the motor pulley cover

in accordance with the direction of rotation of the

sewing machine and attach the pin in the selected

hole using screw 2 and washer 3 supplied with

the unit.

a) If the motor shaft rotates in direction A in the

figure on the above:

/ Attach protecting pin 1 in attaching hole A .

b) If the motor shaft rotates in direction B in the

figure on the above:

/ Attach protecting pin 1 in attaching hole B .

2) Adjustment for the protecting pin and the belt slip-

off preventing bracket

Adjust the position of protecting pin 1 and belt slip-

off preventing bracket 4 in accordance with the

figure on the left.

a) Adjusting the protecting pin

Loosen screw 2 and adjust so that protecting

pin 1 is positioned at the location indicated in

the figure on the left.

b) Adjusting belt slip-off preventing bracket

Loosen screw 5 and adjust so that belt slip-

off preventing bracket 4 is positioned at the

location indicated in the figure on the left.

If protecting pin 1 is not properly adjusted, it

is possible that your fingers may be caught in

the clearance provided between the pulley and

the belt resulting in injury. If belt slip-off

preventing bracket 4 is not properly adjusted,

it is possible to allow the belt to slip off causing

safety hazard.

3) After the adjustment, tighten screws 2 and 5 so

as to secure protecting pin 1 and belt slip-off

preventing bracket 4 to prevent these components

to fluctuate because of vibration.

4) Before starting the operation of the sewing

machine, ascertain that protecting pin 1 and belt

slip-off preventing bracket 4 do not come in contact

with the pulley and the belt.

5. Installation and adjustment for the protecting pin and the belt slip-off preventing bracket

WARNING :

To protect against possible personal injury due to abrupt start of the machine, be sure to start the

5. Detailed explanation of selection of functions

1Selection of the soft-start function (Function setting No. 1)

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.

1 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

100 to MAX rpm <50 rpm>

2Material 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.

(Caution) Setting will be invalid when the material end sensor is not attached, or CP-160 is connected.

3Flicker 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 3

0 : Flicker reducing function does not work. to 3 : 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.

4Bobbin thread counting function (Function setting No. 6)

When the control panel (CP-160) 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.

5Thread 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-160) 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).

1 : on Thread trimming is inoperative. (thread can not be trimmed).

6Setting of the needle bar stop position when the sewing machine stops (Function setting No. 10)

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.

1 : 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.

6. Automatic compensation of neutral point of the pedal sensor

Whenever the pedal sensor, spring, etc. are replaced, be sure to perform following operation :

1) Pressing switch 2, turn ON the power switch.

2) Indication on the screen will be as illustrated in 6.

At this time, the value indicated in the 7 segments

of four figures is the compensation value.

(Caution) At this time, the pedal sensor does not

work properly if the pedal is depressed. Do

not place the foot or any object on the

pedal. Warning sound “peeps” and the

compensation value is not displayed.

3) Turn OFF the power switch, and turn ON the power

switch again to return to the normal mode.

(single sound three times, “peep”, “peep”, and

“peep”), and the setting data returns to the standard

setting value.

(Caution) Do not turn OFF the power on the way

of initializing operation. Program of the

main unit may be broken.

4) Turn OFF the power switch, and turn ON the power

switch again to return to the normal mode.

(Caution)
