Chapter 9 Error code list
Code Error Messages Error Measures
E-49 Can not identify the
machine model
Can not identify the machine
model
Turn OFF the power, check if the model
identification harness is connected properly, and
turn ON the power again.
E-4A I/O CPU communication
error
Failed in the communication with
I/O CPU
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.
E-A1 Main (Z) motor lock Spindle motor lock
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.
E-A2 Main (Z) PCB
temperature is too high
Main PC board temperature too
high
E-A3 Main (Z) motor voltage
is too low Spindle motor voltage too low
E-A4 Main (Z) motor voltage
is too high Spindle motor voltage too high
E-A5 Spindle CPU error Spindle motor CPU error
E-A6 ERROR A6 Spindle motor CPU communication
command error
E-A7 ERROR A7 Spindle motor CPU send/receive
error
This is not usually displayed.
E-A8 ERROR A8 Spindle stop position signal error
Adjust the pulley stop position (100 °) above the
needle and press the . If the error occurs
frequently, the parts related to the main shaft stop
position sensor are faulty.
E-A9 Spindle CPU parameter
error Spindle CPU parameter error
E-B0 Lower shaft CPU error Lower shaft CPU error
E-B1 Thread jammed in
rotary hook Thread tangle in rotary hook
E-B2 Hook motor origin point
error Hook motor origin point error
E-B3 Hook motor standby
position error Hook motor standby position error
E-B4 Hook motor standby
position error Hook motor motor mode error
E-B5 Hook motor
communication error Hook motor communication error
E-B6 Hook motor parameter
error Hook motor parameter error
E-B7 Hook motor overheat
error Hook motor overheat error
E-B8
Hook motor overcurrent
error Turn off the
power
Hook motor overcurrent error
This is not displayed in this model.
E-B9 Thread trimming motor
origin point error
Thread trimming motor zero point
error
Turn the power off and on once. If the same
error occurs again, the lower shaft motor is faulty.
E-BA Power supply frequency
error Power supply frequency 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-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.
