Cause of occurrence expected
• When the machine head is changed.
• When the initialization operation is executed
• When position detection signal is not input
from the sewing machine head synchronizer.
• When the synchronizer has broken.
• When the machine head is locked.
• When sewing extra-heavy material beyond
the guarantee of the machine head.
• When the motor does not run.
• Motor or driver is broken.
• When the machine head connector is not
properly read.
• When tilt detection switch is inputted with
the power ON.
• Position of thread trimmer knife is improper.
• When the motor signal is not properly
inputted.
• When voltage higher than guaranteed one
is inputted.
• When 220V has been inputted at 110V
setting.
• 400V is applied to the box of 220V (230V).
• When voltage lower than guaranteed one
is inputted.
• When 110V has been inputted at 220V setting.
• 110V is applied to the box of 220V.
• Inner circuit is broken by the applied
overvoltage
• Disconnection of operation panel cord
• Operation panel has broken.
• Motor driver has broken.

Items to be checked
• Check the synchronizer connector (CN33,CN43)
for loose connection and disconnection.
• Check whether the synchronizer cord has broken
since the cord is caught in the machine head.
• Check whether the thread has been entangled in
the motor pulley.
• Check the motor output connector (4P) for loose
connection and disconnection.
• Check whether there is any holdup when turning
the motor by hand.
• Check the machine head connector (CN32) for
loose connection and disconnection.
• Check whether machine head is tilted without
turning OFF the power switch (operation of sewing
machine is prohibited for safety).
• Check whether tilt detection switch cord is caught
in the machine.
• Check whether tilt detection switch lever is caught
in the machine.
• Check the motor signal connector (CN30) for loose
connection and disconnection.
• Check whether the motor signal cord has broken
since the cord is caught in the machine head.
• Check whether the applied power voltage is higher
than the rated voltage + (plus) 10% or more.
• Check whether 110V/220V changeover switch is
improperly set.
• In the aforementioned cases, POWER p.c.b is
broken.
• Check whether the voltage is lower than the rated
voltage – (minus) 10% or less.
• Check whether 110V/220V changeover switch is
improperly set.
• Check whether fuse or regenerative resistance is
broken.
• Check the operation panel connector (CN38) for
loose connection and disconnection.
• Check whether the operation panel cord has
broken since the cord is caught in the machine head.
