Problem #19 An error code is displayed after the sewing machine operates.
Cause Inspection/Remedy/Adjustment Replacement if a malfunction
1. If [E120], [E121] or [E130] is
displayed after the sewing
machine operates, there is a
malfunction of the synchronizer,
interference is causing operating
problems, or the sewing
machine is incorrectly adjusted.
1) Check that connector P5 (SYNC) is
connected to the power supply motor P.C.
board and that the synchronizer is
connected.
2) Check the synchronizer input while referring
to “2-8. Input checking method”.
OK if the signal turns on and off.
3) Turn the pulley by hand and check that it
turns smoothly.
4) Check that connector P17 (M_MOTOR) is
connected to the main P.C. board and that
connector P6 (MAIN) is connected to the
power supply motor P.C. board.
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.
Motor assembly CCD-430D
2. If [E150] is displayed after the
sewing machine operates, the
motor is abnormally overheating.
1) Turn off the power and let the sewing
machine stand for 30 minutes.
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.
Cause Inspection/Remedy/Adjustment Replacement if a malfunction
1. Malfunction of synchronizer
Refer to inspection #19.
2. If uneven seams occur, there is
a malfunction of the pulse motor
or the mechanism is incorrectly
adjusted.
1) Refer to inspection #7-3.
2) If uneven seams are occurring because the
work clamp pressure is too weak, adjust the
work clamp lift amount while referring to
“7-14. Adjusting the work clamp lift amount”.
3) If there is play in the feed mechanism, adjust
the feed mechanism.
