Machine Amada Punch
Control O4PC
Machine Referances up OK, but if you move axis in manual it will move but as soon as it stops it alarms out.
Thanks

Check for tightness in X axis ballscrew etc. try with motor removed from screw and see if problem repeats.
What it maybe is, is in homing the axis transitions into slow to seek the marker.
But when jogging the movement is faster and if you have a broken or damaged ball it may be showing up in the faster jog rate. Usually Punches have very high lead ball screws and this can aggravate the problem.

Hi Thanks for the quick reply,
Removed motor from ball screw. still faults out with same alarm.
Thanks

Thats position deviation when stopped, it could be encoder or encoder just off alignment.
There is a procedure to check this, but it is rather involved. First look to see if the encoder has a couple of alignment marks, there is about a 10° adjustment,assuming it is AC servo's.

Hi
Running out of time now its 9.30pm, will let you know tommorow if we find the fault.
Thanks

Look at the value in parameter 594, if it is 0, set pwe
and then enter a value of 200, see if problem goes away,
if not enter 500 and try that. This parameter is the
envelope limiting the area that the control will throw this fault for.

We've had them up to 1000 (1mm) without ever
experiencing any problem with cut.

Range is 593 for x, 594 y, 595 z, 596 4. If you have
more, they go up to 8th axis, paras in manual.

Your fault is referring to the Y axis.

Hi All / to whoes
Need help of this alarm 410 X axis error. Used Fanuc 6M controller.
When NC switch ON, few second alarm appeare 401 & 410.
I was tried exchange servo motor, servo amplifier & mother board. but it still get alarm.

best regards
Rodny

Hi Everybody
I need help on subject above.
I had done a service on machine NC turret punch model: PEGA-204040
Used NC Fanuc controller 6M system.

Alarm appeare when the push button NC press on few second, alarm 401 & 410 appeare.
I was exchange the servo amplifier within X & Y. It get same problem.
I also exchange servo motor from Y to X but it alarm also appeare.
We also change the Fanuc mother board A06B-1000-0030 also same problem.

Any person happen it before, please help & advice.

regards
Rodny Chuah (Malaysia)

Hi all. I have the same alarm... and some times i have axis disconnected alarm.

First checked the motor. i checked it and reinstalled it. then i checked the transistors and changed the x axis for the y axis and the problem solved and the machine was working fine but then i moved it faster and servo disconnected alarm arrised.

I noticed that when i moved the cables from the gabinet the problem happened again...

any ideas?

[cnc int]

I have exactly same problem and i have change, drive, motor, cables, and mother board. Coul you find out the problem?

[ktik]

Hello, I am currently having the same problem. I already changed the cables of the y axis with those of the x when I do it the alarm appears it is in the y axis, so it is not the cables nor the motor, I changed the motherboard of the amplifier module but it was not solved, can you tell me how did they solve the problem? Thank you.

Is this at standstill, moving or rapid ?

[ktik]

Hello, thanks for answering

When it is still, the alarm is not activated, when the speed is low (25%) it turns before it is activated and when it is at 100% it does not even turn. The control is turned off and in the history it marks alarm 410.

If it isn't mechanical, ie tight rails, slideway, ballscrew nut or thrust bearings, it can only be motor or axis drive. Remove the motor and rotate the axis end to end and back, it should be smooth and free using a wrench or hex key to turn the ballscrew.

Another check is if you remove the motor, you can short the 3 phase wires together, and the motor should turn with a lot of resistance but smoothly without feeling "notchy" or uneven. The motor should turn freely. If it has a 24v brake you may need to test that too. If the motor is notchy and tight without the brake it is suspect.

Umm... why do you recommend shorting the 3 phase wires together? That sounds like a terrible idea and results in a phase to phase short....

Hi
What is 3phase wire?!
Pega 244 with 6p control is equipped with DC servos.

Good day everyone, I'm having a similar 410 alarm but it's a bit different. Whenever the motor stop, it will oscillate rapidly and move away from the stop point then the 410 alarm comes up. This happens on the X Axis and sometimes the Y Axis, however, if I gently hold the shaft, it will not oscillate and not alarm
