Problem with Pinacho lathe, Fanuc 21i Hi Community:
I hope you can help me, I need to start a new Pinacho Mustang 200 lathe with Fanuc 21i -TA controler, but every time I do the display show an alarm in red, but there is no alarm number, so the main spindle and the slide donīt run. In addition there is overheating in the electric panel. I couldn't find help in the User manual. Please help me. Thanks.
Arturo
can you take a photo of the alarm,
Also any LED numbers in the electrical cabinet

Hi, MysticMonkey,
I attached the pics of the alarm signal on the screen (see IMG_1470), and on the keyboard (IMG_1474). Inside the cabinet there is no led numbers on (IMG_1468). There is a red LED on at the bottom of the cabinet (see IMG_1466). I have a doubt, there is a key lock inside the cabinet (see IMG_1472), what is it for?; there is also a key hole offside of the cabinet with two positions: work - prep ŋ?.
Thanks for your help.
Contact whoever you brought the machine from.
It looks like you might have a corrupt macro ex script causing the alarm.
In regards to over heating - contact the agency.

From the picture I can not see if there is some LED indicators ON on the servo drives/power supply. If no, check it why, and which power supply is missing - 3x200V (from trafo, breaker, contactor, reactor), or single phase 200V to power supply unit
Hi.
Thanks for your suggestions. I'll contac the vendor.
I found this alarms 750 error axis serial and 5136 FSSB number of amps is small. How can it be fixed up?
Thans, again.
First one means "no communication with spindle drive" second - "no communication with axis drive"
So maybe I am right - the drives are not powered.
Check if there is 200V on CX1A - it is on the left most yellow box just below the LED indicator and comes from the terminal block on the right of the drives. If no, there should be some thermal protection switch or just fuses somewhere.
Was the power on in the electrical cabinet when you took these photos ?
the drives do not look powered up

Thanks to all for your help.
That problem was solved, but now I have another: I can not get the carriage at reference point.
When the lathe is powered on the screen shows the Manual Guide mode, and shows an alarm (300: axis origin return), but the alarm LED is off on the operator's panel keyboard. When I press the symbolic key for reference position return the screen goes to MDI mode (alarm on the screen continues, LED off); then I press the axis direction key (X, Z) but the carriage don't move.
I tried to do it in JOG mode, but every time I press the symbolic key the control goes for MDI mode on the screen.
The slides can be moved in JOG and MPG modes, along/across but that's all.
I'll appreciate your help.
Arturo.
Arturo,
I responed to your PM as well. You are moving the machine off home position in JOG before trying to reference position correct?
Does the reference return push button go off when you switch back to jog mode or does it stay on?
When you have to reference the machine you should have to be in jog so I am not quite sure why it switches to MDI mode. If you press the reference key and the machine switches to MDI mode and then you go to jog mode and if the reference switch goes off then I would assume you have to home in MDI and maybe you have to program a G28U0W0 to reference the machine. I have never seen that before but thats what it appears to me.

Thanks, Stevo.
Before to continue, it may seen silly, how can I know where is the reference point?. I assume that is near the tailstock. The machine's handbook doesn't mention it.
The manual indicates the following procedure:
"1 Press the reference position return switch, one of the mode selection
swithces." (When I do this, the screen goes to MDI mode. No LED on in the key)
"2 To decerease the feedrate, press a rapid traverse override switch." (I press, no LED on). "Press the feed axis and direction selection switch corresponding to the axis and direction for reference position return." (No movement) "Continue pressing the switch until the tool returns to the reference position." (Nothing happens) "... When the tool has returned to the reference position, the reference position return completion LED goes on.".
I remember to have done the same procedure when I worked in a Fanuc Oi lathe before and it worked.
I think something is wrong in the system. That is weird for a new machine.
When G28U0W0 is programmed, the alarm blocks its execution.
I'll tried once again.
Thanks.
Arturo.
