Cause
• In the case the presser fails to operate
because of an excessive load.
• In the case the temperature of the CTL
PCB is excessively high.
• In the case the pitch motor is applied
with an excessive load.
• Pitch motor maloperation.
• In the case the pitch motor is applied
with an excessive load.
• Maloperation of the feed driving motor.
• In the case an excessive load is applied
to the feed driving motor.
• Presser motor maloperation.
• In the case the presser motor is applied
with an excessive load.
• In the case of a program fault.
• In the case the data received from the
network is damaged.
• Mal operation of the needle rocking mo-
tor.
• In the case an excessive load is applied
to the needle rocking motor.
• In the case the needle rocking motor is
unable to operate since an excessive
load is applied it.
• In the case the pitch motor cannot travel
to its origin.
• In the case feed driving motor cannot
travel to its origin.
• In the case the needle rocking motor
has failed to return to its origin.
• In the case of rewriting the main soft-
ware.

Item to be checked
• Check whether the presser motor
runs smoothly.
• Check whether the pitch motor runs
smoothly.
• Check whether the pitch motor runs
smoothly.
• Check whether the feed driving motor
operates smoothly.
• Check whether the presser motor
runs smoothly.
• Check whether or not the needle
rocking motor gets hitched.
• Check whether or not the needle
rocking motor gets hitched.
• Check whether or not the pitch motor
origin is incorrectly adjusted.
• Check whether or not the feed driving
motor origin is incorrectly adjusted.
• Check whether or not the origin of
the needle rocking motor has been
incorrectly adjusted.
• It is not an error.
