Error
code
Error name
Cause of the problem
Status and Measurement
E01
Motor
over-current
Wiring on the motor short-circuited.
The load torque of the sewing machine istoo
large.
Wiring of the motor has disconnected one or two.
Please check wiring on the motor.
Please check the sewing machine.
E02
Motor control IC
over-current
Motor control IC detects Motor over-current.
Wiring on the motor short-circuited.
The load torque of the sewing machine istoo
large.
Please check wiring on the motor.
Please check the sewing machine.
E03
Rise of power
supply voltage
When Power ON, detected high voltage.
Connect the wrong voltage, too high.
Please check the AC power. (Too high)
Please check the main board.
E04
Drop of power
supply voltage
When Power ON, detected low voltage.
Connect the wrong voltage, too low.
Please check the AC power. (Too low)
Please check the main board.
E05
Abnormalities in
the encoder signal
The connector of the encoder is not inserted
completely.
The signal wire of the encoder is disconnected.
Please check the encoder or encoder connectors
and its connection.
Make surethat there is noabnormality in the
encodersignal.
E06
Motor
disconnection
Bad connection at the motor connector.
The connector of the motor is not inserted
completely.
Please check the motor or motor connectors and
its connection.
E07
Synchronizer
(sensor) signal
error
Can not detect synchronizer signal.
Machine locked or object stuck in the motor
pulley.
Sewing material is too thick.
The connector of the synchronizer is not
Inserted completely.
Please check the synchronizer(sensor) or
synchronizer connectors and its connection.
Please check the synchronizer (sensor) and its
signal.
Please check the machine head to see if objects
stuck in the motor pulley, or rotate not smoothly.
E12
Initial magnetic
pole detection
error
When magnetic pole detection signals are
abnormalities at the time of the Power ON.
The connector of the encoder is not inserted
completely.
Wiring of an encoder is disconnected.
Please check the encoder or encoder connectors
and its connection.
Please check that there are no abnormalities in
the magnetic pole detection signal.
E13
pulley ratio
calculation error
Calculation of the pulley ratio is not completed
normally.
The upper position signal has abnormalities.
The upper position signal was disconnected.
Please check the upper position signal connection.
Please check that there are no abnormalities in
the upper position signal.
E16
UVW magnetic
pole detection
signal error
The magnetic pole detection signal has
abnormalities.
The magnetic pole detection signal was
disconnected.
Please check the encoder or encoder connectors
and its connection.
Please check that there are no abnormalities in
the magnetic pole detection signal.
E99
Memory error
When the read-out values of memoryare
abnormalities at Power ON.
After Power OFF,Power ON again the error will
disappear, but all parameter setup values return to
the initial value.
When the abnormalities in a repetition occur, the
component replacement of a main board is
needed.
PF
Power OFF
When Power ON
－＞
OFF [ Switch OFF ].
When power supply voltage is too low.
Please check whether it is the value with right
AC power supply voltage.
※
Displaying, when Power OFF is not Abnormal.
※
When Power OFF at the time of parameter
change is required, it may display (not unusual).
