Machine Lock
Error
The main-shaft of sewing machine
can’t rotate due to some problem.
After user sending order to rotate the main shaft, the main
shaft motor doesn’t respond. Check the PWM curve of the
main shaft motor, the signal of the encoder and whether
there is mechanic problem.
E-039
Main Shaft
Over-speed
The system detects the actual speed of
the main shaft motor exceeding the
speed limit
Turn off the power and repower the machine after a while.
E-040
Current Abnormal
When Stop
Over-current occurs during the stop
process of the main shaft
Turn off the power and repower the machine after a while.
Change the main shaft motor to check if the motor is
damaged; if problem remains, change the main board.
E-043
Thread-trimming
Motor Origin
Search Error
Thread-trimming origin sensor
doesn’t change.
Turn off power and check the connections of CZ026 on
head signal circuit board and X9 on control box.

Error
The verification of the received order
at stepping board is failed
Check the connection of SPI communication cable

Over-Current
Large current is detected by hardware
At first, please check motor. Then check the resistance and
sensor value. If the motor is ok, user should check the
hardware on stepping board

Position Error
The detected encoder response
position is not consistent with the
position set in the order.
Change the stepping motor to open loop mode and run it. If
the motor can work normally, the motor is ok. If the motor
can’t work normally, user should check the driving part on
the stepping board and the motor itself. After the above
operations, user should check the encoder. Make sure the
connection and the condition of the encoder cable is ok.
And make sure the signal response part on the stepping
board and the encoder itself is ok.

The system will give this warning
when it detects the abnormal motor
speed via the encoder response signal.
The checking method is the same with that for Position
