COMMON FAULT
REASON
JUDGEMENT
RESOLVENT
Main spindle running
down
1.short
circuit
or
circuit obstruction
2.transducer
shows
exceptional,
transducer
output
exceptionally
3.main spindle fault
1.using
multimeter
to
measure the on off of
circuit.
2. see whether transducer
shows exceptionally;
measure whether there
is voltage of fan-out
3.whether
transducer
idling normally, load
exceptionally
1.change three core wire of main
spindle
2.adjust transducer diameter;
Change the transducer
3.change or maintain main spindle
One spindle doesn’t
rotate
or
more
spindles
do
not
rotate.
1.input
and
output
circuit exceptionally
2 driver fault
3.screw
of connecting
shaft is loose
1.
using
multimeter
to
measure
the
onoff
of
circuit.
2.whether
the
indicator
twinkle or not;
exchange the two drivers to
test
3. the motor rotates but
the machine doesn’t work
1.change connecting signal line
2.change the driver
3.fix screw tightly
In disorder (motor
fall
out
of
synchronism)
or
engraving
disorderly.
1.drive is hot
2.screw
of connecting
shaft is loose
3. without ground wire or
poor
electric
conduction.
1. there is problem with
driver because of long
time working.
2. the motor rotates but
the machine doesn’t work
3.
there
is
static
of
machine metal parts.
1. change the driver
2. fix screw tightly
3. fix ground wire hard
engraved
size
is
different
from
designed size
Machine diameter is not
correct.

2. DSP handhold user
1.consult manufacturer
2.consult manufacturer
Material
suction
strength is weak
1. the
material
is
turnup or uneven
2. vacuum suction
is
weak
3. Uneven table-board
lead to air leak
1.
to
see
whether
the
material are turnup
2. to feel the suction by
touching sucker mouth
3. there are air leak sound
around brims
1. change the board
2. to check whether there are little
water in the vacuum pump or the
water is too hot
3. use milling cutter to suck the
table- board
Note: little cutters will be ok
