Need Help!- turret issue

[markjb]

2004 puma 240L fanuc 21i-TB we had the servo battery go bad 3.6 volt. we replaced that yeserday ran the machine turned on and ran today for an hour then we got alarm 2023 (not locking in the 10 sec interval) then switches to alam 2047 (turret clamp switch alam or turret control unit alarm

Check your PLC output relay for the clamp/unclamp cct. Chances are both solenoids are in the ON state for the hydraulic turret clamp. This means one of your output relays is fused shut.

When you changed the servo battery. did you reset parameter 8 on the promotion unit ?
This sets the 'current' clamped position tool number

If you hit the e-stop can you turn the turret by hand ?

I got one that has an intermittant turret issue. Works great going CCW but has 2030 error when going CW. I removed and cleaned the Yuken valves. This helped some but still have the error periodically. Swapped battery in servo. Not sure how to reset parameter #8 on promo unit. Any help? Could this be my problem?

Thanks in advance.

Try M-Man's procedure on this thread

Daewoo Puma 300 lathe turret alarm

this is the procedure to reset the position the turret stops at to clamp

I appreciate the response. Still getting 2030 error. (each tool indexing is not finished within 20 sec after tool index command) Thinking it may be the clamp/unclamp confirmation switch. Any thoughts? Thanks.

2030 M17 OR M18 IS COMMANDED IN ILLEGAL MODE, PLEASE CONFIRM MDI MODE.

Please recheck this is the error you are getting



as for checking the turret clamp unclamp

you can either take the guard off and see if the proximity switch at the back is lighting up

or you can change K5.4 and check X7.0 to also see if the clamp confirmation switch is operational.

The fact that it is working in one direction indicates that it is not orientating the turret correctly before it clamps. Which indicates to me that the promotion servo controller is not orientating the turret to the correct position
or overshooting

I turned down the pressure and right now the turret is working w/o errors. It is working slow of course but able to produce parts. I'm going to leave it as is for right now but I do appreciate the responses and may hollar back once it becomes an issue again. Not sure what the pressure had to do with it unless it was running a little high. Again, thanks.

i had similar issue, was actualy the limit prox sensor, had to adjust it.
