ER3 is machine alarm. Check your hydraulic pressure, turret limit switches, spindle motor fan etc.

I checked, hydraulic pressure, turret limit switches, spindle motor fan, thats all normal.
X, Z axits and spindle ok.
If you have manual Fanuc 3t, please help me. Thanks.

Probably the turret is out of position?

Right.
I made ​​the turret back to original position, and I think reference position wrong. But I don't know set up reference position.
Sorry for my english is bad.

How did you move the turret?
If you put in JOG mode and then try to move the turret, will it move?
Sometimes when you try to move the turret to any other position in JOG mode then the turret should index automatically.

I move turret by put into core of hydraulic solenoid valve.
In JOG mode, when I put TURRET INDEX ,the turret not any action.
In DIAGNOSTIC, the signal of sensors and push button ok.

[alexfanuc]

look in the ladder diagram for the turret index signal. It should be a one. Sometimes this sensor fails.
Good luck.

Thanks!
But my machine not have the ladder diagram, only diagnostic table. And I don't have any manual or document for machine.
Do you think the parameters is lost?

[alexfanuc]

If parameters were lost, you would see many alarms at power on. Anyway, check the parameter screen and you should see parameters with values.
In a 3T control you cannot see the ladder in the screen.
Ask in this forum to see if anyone has any documentation for this machine.
It is very hard to find a problem when you don´t have the ladder diagram nor the electric diagram.

If the turret lost its position, you'll need to see how it is being controlled, Probably it is contrlled using a driver, that means that you need to tell to the driver its firts position or home or tool # 1, it is going to be hard because normally I solved many of these problems but using the ladder or schematics...I hope this helps

In this type of machine (with a 3T control) I would check that the front door is closed. Also, check if the select button for the "jog" mode is ok. Can you move the axes in handle mode? Can you ask for a tool and turret moves?

If the control thinks the door is open there will be no movement in jog mode. why would the control think the door is open if you see it closed? because the signal from the door close switch does not work. Check that the signal is changing in the diagnostic page.
You must check in the diagnostic page that the JOG switch is working and that the door switch is also working.
Good luck
