X axis servo error

[Austinbowden]

Hope you are well my friends,

Trying to troubleshoot something

1.103 X AXIS SERVO ERROR TOO LARGE

So I took off covering and verified prox is good..
Interesting- normally light on..
trip light off.?
Usually I feel like light goes on with activated

Anyway
When machine home zero return and I get the error X axis error
Can’t jog before or after the “power up” button - nothing
Nor the “zero return” section
No jog at all

So this might be a clue

If I zero return each axis individually
All axis seem fine
Until X
Then I get the same error
“1.103 X AXIS SERVO ERROR TOO LARGE”

The only clue I might have is if I use zero return section and zero single axis
And when do X independent “single axis” I get same error

After the error I hit reset and the power meter on X goes up to 236% for about 3 seconds and I get a “motor overload” error
Servos go off
I hit reset and hit reset an it does it again
E stop doesn’t stop the endless circle of frustration I get trapped in

Only power off will stop the loop

I don’t know if that is a big clue
It does not occur if I hit “power up”
Only in single axis zero return
And only in X

Swap the x and y cables on the back cabinet and see if the problem moves with it

I swapped them and x is still a problem only
Then I swapped in a servo and problem remains
You would not work when I just did power up, but when I did zero return single axis one at a time I could get the machine moving
However
I tried running at 100% in a program and it has that same error
If I put it to 50% it doesn’t seem to trip that alarm
I have a feeling it’s something in the software
Maybe it has something like zero for the allowed error

And I think they started when we had the power outage during storm

Motor overload is one of those warnings you ignore once, like replacing a fuse. The second time it trips out best to figure out why.
Power off can you manually turn the motor/screw lead? Is it smooth or binding?

Yes, when I swapped out the servo with a servo we had from another machine I had to move the table over quite a bit manually turning the ball screw. And it moved freely.
I have another possible clue from the diagnostic
The all other axis shows
“fault register latch 1” = 0x40
(Binary 100,0000)
But the X axis shows 0X600040
(Binary 1100,0000,0000,00000,0000,0100,0000)
This definitely seems wrong but I cannot say cause

Sorry
0xC0000040 is the value on “fault register latch 1”

Have you checked the gridshift?
