Cause
・ Buffer for storing ISS data will soon
be filled to its capacity.
If the buffer is used continuously,
the stored data will be automatical-
ly erased on FIFO basis.
・ When the predetermined number
of stitches is reached.
・ In the case the sewing machine
cannot continue sewing since the
predetermined number of stitches
is reached.
・ In the case the Tilt detection switch
is turned ON when the power to
the sewing machine remains ON.
・ In the case the meniscus sensor
signal cannot be detected.
・ In the case of attempting to delete
the pattern which is used in a cycle
pattern.
・ In the case of attempting to delete
the custom pitch or condensation
custom which is used in a pattern.
・ In the case the password entered
is wrong.
・ In the case the number of pass-
word characters entered is not
enough.
・ In the case of attempting to create
eleven or more polygonal stitching
patterns.
・ In the case the custom pitch num-
ber is faulty.
・ In the case the condensation cus-
tom number is faulty.
・ In the case of file name that al-
ready exists.
・ In the case the keylock could not
be released.
・ In the case the system version
does not match the machine head
setting.
・ The NAND flash memory is not
formatted.
・ The NAND flash memory is not
accessible.

Item to be checked
・ Output the ISS data.
・ Add grease to the specified points of sew-
ing machine and reset the error.
・ Add grease to the specified points of sew-
ing machine and reset the error.
・ Check whether the machine head is tilted
before turning OFF the power switch (The
sewing machine operation is prohibited for
the sake of safety.)
・ Check for a break in the motor encoder
connector.
・ Re-write the system version to the applica-
ble one.
