Chapter 11 Error code list

Code	Error	Measures
E-43	Slave I/F EEPROM read error	Turn the power off and on once. If the same error occurs again, the main
		PC is faulty.
E-A1	Spindle motor lock	Press the STOP or turn on the F/B switch on the head to either side. If it
		occurs frequently, the main shaft mechanism is faulty.
E-A2	Main PC board temperature too high
E-A3	Spindle motor voltage too low
E-A4	Spindle motor voltage too high
		This is not usually displayed.
E-A5	Spindle motor CPU error
E-A6	Spindle motor CPU communication command error
E-A7	Spindle motor CPU send/receive error
		Adjust the pulley stop position (100 degrees) above the needle and press
E-A8	Spindle stop position signal error	the STOP . If the error occurs frequently, the parts related to the main shaft
		stop position sensor are faulty.
E-A9	Spindle CPU parameter error
		This is not usually displayed.
E-B0	Lower shaft CPU error
E-B1	Thread tangle in rotary hook	Check to see that no lint is tangled in the rotary hook and press the STOP or
E-B2	Hook motor origin point error	turn on the F/B switch on the head to either side.
		The rotary hook may be rotated forcefully. Press the STOP or turn on F/B
E-B3	Hook motor standby position error	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 motor mode error
E-B5	Hook motor communication error	This is not usually displayed.
E-B6	Hook motor parameter error
E-B7	Hook motor overheat error	Turn the power off and on once. If the same error occurs again, the lower
E-B8	Hook motor overcurrent error	shaft motor is faulty.
E-B9	Thread trimming motor zero point error	Turn the power off and check the thread trimmer and turn the power on
		again. If it occurs again, the thread trimmer is faulty.
E-BA	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.
E-BC	No power error	It may usually occur momentarily when turning off the machine. If it occurs
		when the machine is on, it is a power failure detection error.
E-BD	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	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-BB, BF	Lower shaft motor undefined error	This is not usually displayed.
E-C1	Area over during embroidering	Set the embroidering area again on PC.
E-C2	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.
