Chapter 9 List of Error Messages

Code	Error Messages		Error		Measures
	Main shaft stop position sensor			Adjust the pulley stop position (100 degrees) above the needle
E-A8			Main shaft stop position signal error	and press the STOP . If the error occurs frequently, the parts
	error
				related to the main shaft stop position sensor are faulty.
E-B0	Lower shaft CPU error		Lower shaft CPU error	This is not usually displayed.
E-B1	Thread jammed in rotary hook		Thread tangle in rotary hook	Check to see that no lint is tangled in the rotary hook and press
				the STOP or turn on the F/B switch on the head to either side.
E-B2	Hook motor origin point error		Hook motor origin point error
				The rotary hook may be rotated forcefully. Press the STOP or
E-B3	Hook motor standby position error		Hook motor standby position error	turn on F/B switch on the head to either side to cancel the
				error. If the same error occurs again, the lower shaft sensor
				is improperly adjusted.
E-B4	Hook motor standby position error		Hook motor motor mode error
E-B5	Hook motor communication error		Hook motor communication error	This is not usually displayed.
E-B6	Hook motor parameter error		Hook motor parameter error
E-B7	Hook motor overheat error		Hook motor overheat error	Turn the power off and on once. If the same error occurs
E-B8	Hook motor overcurrent	error	Hook motor overcurrent error	again, the lower shaft motor is faulty.
	Turn off the power
E-B9	Thread trimming motor	origin	Thread trimming motor zero point error	Turn the power off and check the thread trimmer and turn the
	point error			power on again. If it occurs again, the thread trimmer is faulty.
E-BA	Power supply frequency error		Power supply frequency error	Turn the power off and on once. If the same error occurs
				again, the power PCB or power supply is faulty.
				It may usually occur momentarily when turning off the ma-
E-BC	No power error		No power error	chine. If it occurs when the machine is on, it is a power failure
				detection error.
E-BD	Lower shaft flash memory error		Lower shaft flash memory error	Turn the power off and on once. If the same error occurs
				again, the main PCB is faulty.
E-BE	Lower shaft version-up error		Lower shaft version-up error	Press the	STOP or turn on the F/B switch on the head to either
				side to cancel the error and upgrade the version again.
E-BF	ERROR BF		Lower shaft motor undefined error	This is not usually displayed.
E-C1	ERROR C1		Area over during embroidering	Set the embroidering area again on the panel.
E-C2	Wiper out error		Wiper out error	If the wiper is tangled with a thread, remove it. Press the STOP
				or turn on the F/B switch on the head to either side.
E-C3	ERROR C3		Embroidering data buffer empty	This is not usually displayed.
				Press the	STOP or turn on the F/B switch on the head to ei-
E-C4	Presser foot down error		Presser foot down error	ther side.	If the same error occurs again, adjust the
				presser foot switch.
E-C5	ERROR C5		Measured voltage value could not be received	This is not usually displayed.

				The machine may be being tested in the BC test mode. Exit
E-C7	ERROR C7		Lower shaft error	the test mode or turn the power off and on once. If the same
				error occurs again, the main PCB is faulty.
E-C8	ERROR C8		Hook motor origin point error	Check the operation of the main shaft brake and the stop posi-
				tion of the main shaft (100 degrees).
E-C9	Embroidering start error		Embroidering start error	This is not usually displayed.
E-CA	ERROR CA		No sewing permisson	This is not usually displayed.
				Press the STOP or turn on the F/B switch on the head to either side
E-CB	Spindle rotation speed error		Spindle rotation speed error	to cancel the error and press the		. If the same error occurs
				again, there is a possibility that the spindle is overloaded.
E-CD	ERROR CD		Speed command can not be received.	Turn the power off and on once. If the same error occurs
				again, the main PCB is faulty.
E-CE	Cylinder bed position error		Cylinder bed position error	Secure the bed. If the bed is secured, the bed sensor position
				may be faulty. Readjust it.
E-CF	ERROR CF		Rated voltage value could not be received from	Turn the power off and on once.		If the same error occurs
