E - 008 Supplementary device
(24V) over-voltage
1
、
Check the connection of cable L451 (X16 Port
Cable on control box)
；
2 、 Check needle-thread-trimming motor and bobbin
thread-trimming motor E

009 Supplementary device
(24V) low-voltage
E - 013 Encoder error or
unconnected
1
、
Check the connection of Main motor cables (X4 &
X5 Port Cable on control box)
2
、
Make sure the mechanical part is not blocked
3
、
Check the condition of main motor

014 Motor running error
E
-
018 Knife position error
1 、 Check mechanical installation. Make sure the
knife can return to the origin and the light shield
can cover the sensor
2 、 Check the connection of L438 Cable
3
、
Check the connection of cable L453 (X9 Port
Cable on control box)
4 、 Enter Test Mode and check the working condition
of knife sensor. It should display “OFF” at being
covered, and “ON” at being exposed
5
、
Check the condition of knife solenoid and the
connecting cable. Use parameter K05 to change
the working current of knife solenoid. User can
check the working condition of it in test mode

Knife sensor error
E - 025 X origin detect error 1
、
Check installing position of mechanical devices,
especially the sensor. Generally speaking, the
distance between the sensor and the shielding
sheet should be kept at 3mm
；
2
、
Check the cable of the needle-rocking sensor, as
well as its connection
3 、 Check the connection of cable L453 (X9 Port
Cable on control box)
；
4 、 Check the needle-rocking motor and its cable
connection (X15 Port Cable of Control Box);
5
、
Enter the Test Mode and check the needle-rocking
origin sensor. When the needle is at left, the
system should display “OFF”, while the “ON” at
right. Push the needle from right to left or from
left to right, and check the change of display. If the
display changes more than once, please adjust the
installation position.
E - 026 Y origin detect error 1
、
Check installing position of mechanical devices,
especially the sensor. Generally speaking, the
distance between the sensor and the shielding
sheet should be kept at 3mm
；
2 、 Check the cable of the feeding origin sensor, as
well as its connection
3
、
Check the connection of cable L453 (X9 Port
