5)

Check the harness between connector P17

 

 

 

 

 

 

 

 

 

(M_MOTOR) of the main P.C. board and

 

 

 

 

 

 

 

 

 

connector P6 (MAIN) of the power supply

 

 

 

 

 

 

 

 

 

motor P.C. board.

 

 

 

 

 

 

 

 

 

6)

Check that the ground wire is connected to a

 

 

 

 

 

 

 

 

 

secure ground and that there is no equipment

 

 

 

 

 

 

 

 

 

nearby that is generating strong electrical

 

 

 

 

 

 

 

 

 

interference.

 

 

 

 

 

 

 

 

 

7)

If [E121] is displayed when the sewing

 

 

 

 

 

 

 

 

 

machine stops:

 

 

 

 

 

 

 

 

 

 

Check if the thread trimming solenoid is

 

 

 

 

 

 

 

 

 

operating.

 

 

 

 

 

 

 

 

 

 

Adjust the thread trimming mechanism.

 

 

2.

If [E150] is

displayed

after

the

1)

Turn off the power and let the sewing

machine

operates,

the

 

machine stand for 30 minutes.

 

 

 

motor is abnormally overheating.

2)

Turn the power back on; OK if operation is

 

 

 

 

 

 

 

 

 

normal.

 

 

 

 

 

 

 

 

 

3)

If the area around the motor is not hot, carry

 

 

 

 

 

 

 

 

 

out the steps for [E121].

 

 

 

 

 

 

 

 

 

Avoid repeated sewing of sewing data that is

 

 

 

 

 

 

 

 

less than 15 stitches.

 

 

 

 

 

 

 

 

 

Problem

#20

Sewing is incorrect.

Inspection/Remedy/Adjustment

 

Replacement if a malfunction

1.

Malfunction of synchronizer

 

Refer to inspection #19.

 

 

 

 

 

 

 

 

2.

If uneven seams occur, there is

1)

Refer to inspection #7-3.

 

 

 

a malfunction of the pulse motor

2)

If uneven seams are occurring because the

 

 

or the mechanism is incorrectly

 

work clamp pressure is too weak, adjust the

 

 

adjusted.

 

 

 

 

 

work clamp lift amount while referring

to

 

 

 

 

 

 

 

 

 

“7-14. Adjusting the work clamp lift amount”.

 

 

 

 

 

 

 

 

3)
