Measures
Turn OFF the power, check if the model
identification harness is connected properly, and
turn ON the power again.
Press the
or turn ON the F/B switch on the
head to either side. If the same error occurs
again, the connector of communication cable on
the I/O PCB may be disconnected.
Press the
or turn on the F/B switch on the
head to either side. If it occurs frequently, the
main shaft mechanism is faulty.
This is not usually displayed.
Adjust the pulley stop position (100 °) above the
needle and press the
frequently, the parts related to the main shaft stop
position sensor are faulty.
This is not displayed in this model.
Turn the power off and on once. If the same
error occurs again, the lower shaft motor is faulty.
Turn the power off and check the thread trimmer
and turn the power on again. If it occurs again,
the thread trimmer is faulty.
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.
