16 Analysis of Actual Failure Cases
Description of the Failures
Possible Causes
Remedies
1
After reading the pattern, the machine fails to
knit pattern during operation
Origin sensor device is loose and is
not triggered
Re-adjust the origin position and tighten
2
It prompts: "data processing failed" while
reading the pattern
The setting value of "Actuator
angle ORG-001" is negative
Re-set this value to zero
3
The needles count in the Jacquard interface
can +1 only after the needle cylinder rotates 1
revolution
"Synchronizer rotation direction" is
set incorrectly
Changes "memory function→preliminary
instructions→synchronizer
rotation
direction"
4
It can knit patterns normally during jogging
and slow operation, but it sometimes can knit
patterns and sometimes cannot knit patterns
after pressing the start key.
The distance between the sensors
and the sensing metal is too large,
sometimes can sense, sometimes
cannot sense
Properly adjust the sensor position in a scope
about 1.5 ~ 2.5mm
5
72-unit yarn change machine
Site status:
1. Check the screen and yarn, the test results
are normal
2. After entering yarn change jacquard mode,
the first finger does not move, the other
fingers are normal
3. Set finger 1 to the initial position, after
entering yarn change mode, finger 1 does not
move and is unable to retract
Finger fine tuning angle setting
error or the corresponding data line
connection error
1. Check whether the corresponding data
line is connected correctly
Check the finger fine tuning angle setting,
generally this value is 0
6
1. Jacquard is normal after the machine is
started
2. Pattern knitting becomes confused after the
machine runs a period of time
3. It becomes normal after being re-adjusted to
zero
4. The problem reoccurs after the machine
runs a period of time
The synchronizer can not normally
locate the mechanical position
1. Check whether the connection between the
synchronizer and the gearbox is normal
2. Check whether the coupling is damaged
3. Check whether the coupling and the
machine slips during operation (can view the
synchronizer adjustment screen at low
speed synchronous adjustment screen, check
whether the pulse is changing uniformly)
4. Check whether the large gear and the
gearbox of the machine are normal
7
After reinstalling the origin sensor, the
jacquard needles do not move and the
interface stays in the initial needle movement
state and do not enter the jacquard operation
menu
1. The position of the sensor varies
from the pattern starting point of
synchronizer
2. The sensing metal supporting the
sensor acts too short a time
1. Adjust the position of the origin sensor
2. Increase the acting area of the sensing
metal
8
1.
Irregular
patterns
appear
during
commissioning of the new machine
2. Actuator lead or lag the correct positions in
slow operation
3. Check and confirm that the functions and
movements of the actuator are correct (1X1A,
code confirmation )
Synchronizer Setting Error
Reset after confirming the synchronization
ratio
