Error description
Code
E203 The main motor error
E204 The main motor direction
error
E205 Pressure box didn't put
down
E206 Failure of head board
E207 Input IO timeout error
E208 Air pressure is insufficient
E209 Motor scissors are not in
place
Fault Cause
1. The winding is normal but the
work occasionally reports that the
power board software and hard-
ware are too old
2. The main shaft is stuck
3. The parameters are incorrect,
such as P665 to P668
4. The main shaft encoder cable is
broken or has poor contact.
5. The main shaft motor is broken
6. Power board or motherboard
hardware is bad
7. The motherboard and the power
board connected to the dress
rehearsal line poor cont act
1. The main motor direction parame-
ter is set incorrectly.
2. Occasionally reported as a power
board failure
The current frame is in the raised
state
1. Bad head cable
2. The head plate is damaged
3. The motherboard is damaged
1. The corresponding input IO wiring
or sensor is broken
2. The corresponding input IO mech-
anism cannot be triggered
3. Parameter or file setting error
4. The sensor or PCB board where
the corresponding IO is located is
broken
1. Insufficient air pressure
2. Pressure detection device failure
1. The parameters are incorrect,
such as the polarity of the thread
trimming
2. Poor or broken wiring of trimmer
zero sensor
3. The sensor or motor coupling is
loose and offset
4. Scissor motor is stuck
5. Motor damage
6. The motor corresponding driver
board is broken

Solution
1. See "Internal Drive Preview" - "Main
shaft" - "Version Number" on the
screen. If it is lower than 2, you need to
update the program.
2. Manual rotation, check the machinery
3. Reset or redirect parameters
4. Check the wiring; manually turn around
to see if the screen QEP changes one
cycle, and see if the "main shaft 0 bit
level" changes once. If there is no
change, it means that the encoder wire
is broken or the motor is broken or the
power board is broken.
5. Replace the main shaft motor
6. Replace the power board or mother-
board
7. Check the connection cable
1. Change the main motor direction pa-
rameter in the software or screen
2. Replace the power board
Click the "Frame" button to lower the press
frame
1. Check the headboard connection line
2. Replace the head board
3. Replace the motherboard
1. Test wiring or sensor
2. Check the mechanical structure
3. Check or redirect parameters and pro-
cessing files
4. Confirm whether the corresponding IO
can be triggered manually in the "input
test" screen, if not, replace it.
1. Check if the air supply is normal
2. Check the air pressure detection device
1. Reset parameters
2. Check the wiring or replace the sensor
3. Inspection machinery
4. Check the scissors motor
5. Replace the motor
6. Replace the corresponding driver board
