Failure
Cause
Solution
Remark
⚫
A certain axis has no
action during initialization
and the motor has no
motion sound
⚫
Initialization is always in
the state that can’t be
finished
⚫
The only method is to
turn off the power
➢
Confirm the fault
axis
The axis that causes the initialization failed
is the fault axis (initialization sequence: Z-
X-Y)
Normal initialization:
➢
Z axis collides downwards with
limit once;
➢
X axis collides backwards with
limit twice;
➢
Y axis collides rightwards with
limit twice;
➢
Motor wire of fault
axis broken, needle
retreated, plug loose
➢
Check if the motor of
the fault axis is
damaged
Turn off the power, check if the motor wiring of
the fault axis is damaged, and if the plug is broken;
if not, remove the mainboard and check if the
motor wire is broken or if the plug is loose
Turn off the power, open the rear panel, plug an
intact motor into the motor terminal of the
mainboard, and then initialize and test the motor
for damage. Replace the motor of the fault axis
➢
After abnormal initialization by
touching the limit with hand, push
each axis by hand to see if there is any
power failure
➢
Mainboard damaged
Turn off the power and replace the mainboard
➢
CPU damaged
Turn off the power and replace the CPU
Failure 02: Initialization failed: no action on an axis
