E-B9	Thread trimming motor	Thread trimming motor zero point	Turn the power off and on once. If the same
	origin point error	error	error occurs again, the lower shaft motor is faulty.
E-BA	Power supply frequency		Turn the power off and check the thread trimmer
		Power supply frequency error	and turn the power on again.			If it occurs again,
	error
			the thread trimmer is faulty.
E-BC	No power error	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.
