Error Error description
Code
E001 There is no reset
E002 Couldn't find X zero signal
E003 Couldn't find Y zero signal
E004 Couldn't find Z zero signal
E005 Couldn't find U zero signal
E006 Couldn't find Extend zero
signal
E007 Main shaft without internal
zero signal
E020 X axis overvoltage
E021 X axis undervoltage
E022 X axis hardware over cur-
rent
Fault Cause
The machine is not reset or reset
abnormally after power on
1. X-axis limit sensor is bad or wiring
is bad
2. The sensor or baffle screws are
loose, or the mechanical jam
causes the sensor not to be
moved.
3. Parameter errors, such as X-axis
reset direction, polarity, platen
size, etc.
1. Main shaft encoder wiring is bad
2. The main shaft encoder is dam-
aged
3. Power board is broken
4. The motor is broken
1. Overload when the load is too
heavy and the idling speed is too
fast to stop
2. The main board or power board is
broken, and the X axis detection
voltage exceeds 92V.
1. The mains voltage is too low
2. Power board failure
1. The X axis motor is broken or the
motor wire is broken and short
circuited
2. The motherboard is broken

Solution
Click the "Reset" button to reset
1. Check the sensor wiring, manually trig-
ger the sensor, and see if there is any
change in the "input test" X limit text on
the screen. Replace without change
2. Check the structure
3. Reset or redirect parameters

1. Check the wiring of the main shaft en-
coder
2. Replace the main shaft motor
3. Replace the power board
4. Replace the motor
1. Decrease the idling speed
2. Screen menu auxiliary settings drive
preview internal drive preview look at
the current voltage of the XZ axis, if it
is not between 80 92V, it means that
the power board is faulty, you need
to replace the power board. If one of
them is within this range, it means the
motherboard Bad need to change the
motherboard.
1. Check whether the voltage of the X
axis driver is lower than 180V, and see
if there are high power devices around
the device that start and stop frequent-
ly; equipped with a voltage stabilizer
according to the situation.
2. Replace the power board
1. Replace the motor
2. Replace the motherboard
