Solution
Make sure the pedal is not stepped down when
entering the ready sewing status
Restart or return-to-origin after pressing
RESET key for thread-trimming.
The sewing machine cannot be operated with
the head tilted. Return the sewing machine
head to its proper position. Technicians can use
short circuit board to short circuit the 2P blue
plug on the head board.
Turn off the power and repower the machine
after a while.
Turn off the power supply and then turn it on
again after a while.
Shut down the machine to check if there is any
short circuit
Turn off the power and check connection of the
CZ025 at the head signal circuit board. If the
connection is ok, check the optocoupler.
Turn off the power, and confirm whether plug
X5 is connected properly.
Shut down the machine to check the motor
encoder.
Press RESET switch to confirm the pattern and
its X/Y scale rate.
Triggering condition: pattern computation
error.
The main shaft stop position error may be
caused by main shaft drive, or may be caused
by human error. Turn the hand wheel to return
the needle bar to its UP position.
The spindle parking position is wrong, which
may be the cause of the spindle drive, or it may
be caused by human rotation. Turn the
handwheel to return the pin holder to the upper
position.
Turn off the power and check the connection of
the CZ024 at the head signal circuit board. If
the connection is ok, check the optocoupler.
