I am now pretty sure that the problem is in the servo amplifier itself.

Input voltage to the drive is OK.

On the top of amplifier, there are three pins B1, B2, B3 and there is voltage between...

No, the Z drive is single axis
and for X / Y is one together (A06B-6058-H229).

When I power on machine, I get alarm
434 SERVO ALARM : Z AXIS DETECT ERR
...sometimes combined with
403 SERVO ALARM : (VRDY OFF)

And I can not start machine.
This used to happen in past, but I...

No ideas fot solving this problem? :idea:

That is 0.10 - 0.15 mm, exactly as it was before my adjustment/reduction.

During this night I got another idea:
Maybe encoder of Z axis is bad - giving non-constant position,
and spindle tries...

I haven't solved my problem because I didn't had any needs to make taping for last few months. Now I need this function so I tried something...

I tried to adjust gap between sensor and toothed...

Thank you for your answer, BUT:
- I don't get any alarms, since now (may be in the future)
- during the orientation (M19), there is no buzzing heard

"the adjustment gap is set wrong"
That is...

That would be an sensor for reference of spindle?

Where this sensor should be, inside of the motor?

Manual adjustment (moving) or with parameters?



There is no spindle load meter on...

My coworker says that it used to happen also in past,
but just occasionally, with less intensity,
and much silently.
And it newer stopped before.

Machine - V.M.C. - KIA KV25
Control - Fanuc 0M

The problem came out suddenly, without any change on machine/control.

When machine starts to rigid tap, it immediately starts buzzing very loud....

Perfect!

So Predator does have all features that I have been dreaming about.

I asked for access code for timed evaluation of Predator (with NIC number) but no answer for a very long time. Why?

Yes, I found these parameters.
If I have all program without % at begining and at end of programs, first program that is sent is lost, not recognized.

If I have all programs with % at begining of...

So do I need to push INPUT button for every of these programs, or it can be done with only one INPUT push?

That is only question that remained unanswered.

Thank you very much for help.

PUNCHING
Is it possible that every program that is punched will be saved in it's own file and under same name as program number is?

READ (INPUT)
Is there any explanation how remote request...

Can someone explain this?
Obviously you should have software with this feature?
Which for example?

BTW, sorry for bumping really old thread.

I am writing thesis (final essay) for my university, and the topic is "DNC technology".

I would be very thankful if anybody could give me some hints for literature on this topic (links, e-books,...

Very good question. I have not checked it before.
Now I see that G13.1 IS ACTIVE when I get alarm.
It means that circular interpolation is CANCELED.

So why it wants to move "X and C" when I give...

Any other ideas?

I have tried to put G1 X0 F1 instead of G0 X0 but no help.
I tried to put some other value for X different than 0. No help.

In every case when machine reads this line in...

Tried this before and now again, doesn't help.




It is G0 X0 for sure. In other case, when I push RESET and continue program from this tool, at line (CENTER DRILL 8 TM), it would alarm again....

I think this is not used on my machine...
For M43 manual says "Chuck Clean Off".

I have done pretty much programing (cutting) with C-axis since now, always using same principle, and never had...

Machine is lathe Romi G15SM
Control Fanuc 18i-TA
Alarm: 197 C-AXIS COMMANDED IN SPINDLE MODE

Here is whole program.
Machine stops and alarms at point "PROBLEM" in red color.
When machine reads...

I checked the cable again. One wire was broken again, I soldered it.
Again checked cable with multi-meter, everything is OK.

Now there is no OVER LOAD alarm, after power on I can move X and Z...

I have done it before posting problem here, it moves by hand without problem.




I haven't done this, but I disconnected connector from the motor and opened it.
One wire was broken. I soldered...

VMC (Kia KV25), Fanuc 0M

Machine was working normally.
Suddenly, it started to give next alarms (in different combinations):
426 SERVO ALARM: Y AXIS DISCONECT
401 SERVO ALARM: (VRDY OFF)
421...

Machine: KIA V25P
Control: OM

While dual table was in operation (rotating), worker turned the mode selector from auto to edit and table stopped.

Now there is alarm J/C POSITION ERROR

I have...

Problem solved, I got from machine builder the procedure for turret zero point.
The catch is parameter #11 bits 0 and 7.

OK, I changed the battery.
BUT, now there are two new problems.

1. It gives me wrong tool, not the one I have commanded.
In the manufacturer manual there is no word about turret referencing or...

Machine is Lathe ROMI G15SM, 2001. y.

There are two alarms:
1005 TURRET SERVO AMPLIFIER FAILURE

I do not know if these two alarms have...

Thank you very much, that works :)

I have ROMI lathe G15SM 2000. y. with driven tools and C axis.
Control is Fanuc 18i-TA.

So, here what I want to do.
First I have to make some operation with milling, than make some turning, and...
