Cause of occurrence expected
• When the machine head is changed.
• When 3-phase input is missing, and single
phase operation is performed.
• When input voltage is less than the guaranteed
voltage.
• When fall detection switch is inputted in the state
that the power is turned ON.
• When position detection signal is not inputted
from the sewing machine head synchronizer.
• When the synchronizer has broken.
• Disconnection of operation panel cord
• Operation panel 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.
• When the machine head connector is not
properly read.
• When the short-circuited solenoid is desired to
be driven.
• When voltage upper than guaranteed one is
inputted.
• When 200V is inputted for 100V setting.
• When voltage lower than guaranteed one is
inputted.
• When 100V is inputted for 200V setting.
• Motor driver has broken.
• When the motor signal is not properly inputted.

Items to be checked
• Check the power plug and receptacle for loose
connection and disconnection.
• Check the power switch terminal for loose
connection and disconnection.
• Check whether power fuse has blown.
• Check whether input voltage is lower by -10%
than the rated voltage.
• Check whether the machine head is tilted
without turning OFF the power switch (sewing
machine operation is prohibited for safety sake).
• Check whether the fall detection switch cord is
caught in the sewing machine or the like and
has broken.
• Check whether the fall detection switch lever is
caught in something.
• Check the synchronizer connector (CN9) for
loose connection and disconnection.
• Check whether the synchronizer cord has
broken since the cord is caught in the machine
head or the like.
• Check the operation panel connector (CN17)
for loose connection and disconnection.
• Check whether the operation panel cord has
broken since the cord is caught in the machine
head or the like.
• Check whether the thread has been entangled
in the motor pulley.
• Check the motor output connector (4P) for loose
connection and disconnection.
• Check the machine head connector (CN11) for
loose connection and disconnection.
• Check whether the solenoid is short-circuited.
• Check whether the applied power voltage is
higher than the rated voltage + (plus) 10% or
more.
• Check whether 100V/200V changeover
connector is set by mistake.
In the above cases, POWER circuit board has
broken.
• Check whether the votage is lower than the
rated voltagw - (minus) 10% or less.
• Check whether 100V/200V changeover
connector is set by mistake.
• Check the motor signal connector (CN13,
CN41) for loose connection and disconnection.
• Check whether the motor signal cord has broken
since the cord is caught in the machine head or
the like.
