Potential Issue(s)
1. Kinetic occurs obstruction
phenomenon.
2. Servo drive occurs
unexpected Servo ON / OFF.
3. CPU board send the data to
axis card unsuccessfully
(CPU board or axis card has
problem, the contact between
CPU and axis card is not
good).
4. The cable that sends
command from controller to
servo driver has poor quality
or is disconnected.
5. Controller doesn't set servo
drive alarm check, controller
continues to send motion
command although the drive
is abnormal.
6. Local interference.
Resolution(s)
1. Do not shut down the
controller when alarm
occurs. Please check
whether the value of No 8,
9, 10 in diagnose function is
zero (0).
2. Check whether the
mechanical lubrication
system is good.
3. Open the cover of axial to
check whether foreign
matter blocks the motion of
axial.
4. Rotate screw to check
whether machine is stuck
(loading of driver).
5. Check the drive servo-on
and the servo-off of power
or cable signal.
6. If the setting value of No 8,
9, 10 in diagnostic function
do not change, please take
home search action (don't
need to reboot), after that
check whether parameters
24, 25, 26, 40, 41, 42 are
equal to zero (0), if the
parameters 24, 25,26 are
not equal to zero (0), the
feedback loop has
problems.
7. If all parameters 24, 25, 40,
41, 42 are not zero (0), then
the interference signal is
relatively large, specifically
in the machining process,
the setting value of
parameters 8, 9 , 10
gradually become large. The
reason is the contact point
between CPU board and
axis card is not good. Try to
replace CPU board and axis
card.
