Need Help!- Fanuc 3t system start up

[Motopsych]

Hello, new to board and am having problem with Tsugami lathe I just purchased. Rigged in today and went to power up. Runs startup sequence and will not come out of "not ready" on the crt screen. Servo drives also show not ready in control panel. Wondering if battery is dead or wrong supply power( previous owner had it set on 240vac and I have 213 vac at machine).
Any help on this machine would be appreciated, as they say the clock is ticking for production.
Also any insight on finding machine manuals?
Thanks
Jeff

I am not sure about the 3, but the 6 requires the correct input power phase rotation to power up.

Al , tried the rotation switching two legs. Will try dropping the input voltage on the transformer Monday. I switched from the 240 tap to the 220 tap but will try dropping to the 200 vac tap to boost over 198 on secondary. Do you know what power the servo drives(Fanuc) are supposed to see?
Also do lathes need to run a home program operator started or is it an auto function on power up?
Thanks for the help, losing what little hair I have left!

You really need the service manual and schematics to ensure the correct voltage, normally the AC measured on the R,S, terminals to the controller should read 200v.
My 3 manual shows the allowance to be 170 to 240.
This is a good sign that you are withing tolerance of the supply.
Most servo three phase in is 185v between phases.
Some lathes require zeroing before the machine will run in auto, this is done manually.

Al will try in AM, maybee your advice and a clear head will come up with something. If not i'll shower it with hot coffee and breath smoke on it as a welcome to my shop!Thanks Again!

Hi,
This may sound like I'm assuming you are stupid, but that's not the case. Often Fanuc controls require another button to be pressed after the control is up: NC On, or Mach on, etc. What's more, some require air pressure before they will come on. Is it low on lube oil? Is there anything in the "Message" or "alarm" screen? Also sometimes the machine will not come on when the tool changer is in an inappropriate position, as often happens after transport - depending on the manufacturers ladder programming.

3t sounds like it might be pretty old. Yes, if the battery is low on old controls you may have lost the parameters, hopefully you have a backup copy? If not, and that's the case, it may cost you megabucks to get the parameters restored, assuming the manufacturer (not Fanuc) doesn't have a record of the parameters (usually they don't). If you change the batteries: Do so with the power on, that way you do not loose the parameters by doing so.

M controls, no offense taken. I don't know much about CNCs and after looking around on the board at other programming questions I know even less! Will try all you guys have been telling me, I had no ops messages and no alarms and I certainly pushed all the buttons. The machine is an early 90's Tsugami and I have some of the bits on a hand written sheet someone made. I bought another lathe at same time and powered it on yesterday as well . I'll need an entire book of problem writing for that one though.
Will try playing in morn and post what silly thing I am forgetting.
Always go KISS first.
Thanks

Moto I have maintance manual's for my 3T Tsugami I think they are in the early 80's with a 3T seem's the machine tag or serial# tell's build date I have a paramater list for mine Email a Pic of your's and maybe I can spot what switch is in the wrong position Email ktaylor253@earthlink.net Good luck Kevin

Guys, tried all I can think. Lube sensor jumped out years ago by someone. z axis had over traveled and I hand turned both to make sure switches were clear. Machine has no air , it is a gang type with no turret. Power to all areas (control , servos) seems correct. In the control panel I found two connectors were off . They are #189 and #186 from the bottom of the AXES board one of which is marked X also. I reconnected them and did the "pull the boards" routine for shipping jiggle. Front of the AXES board has three pin connector that is not used(looks like power hook up) and I can't find cable that would have gone to it (I am assuming this is used on different app?) One small idiot light inset of this connector that is not illuminated. Power supply module on this rack is lit with a green. Battery looks good and memory seems intact ( not to say that a setting is not off, but from the hand notes looks like they are still good). Still get the same message on all screens "not ready". Power main, control power on, crt becomes visable, I immediately see the not ready in the lower left corner of screen. It allows me to use the keypad but none of the operator controls. Seems it is waiting for signal from the servos to tell it to release? Also all fuses I can find ring good?
On the rack in front control cabinet it is marked "Fanuc OT" not 3T like the other papers are marked, possible retrofit?
Thanks Again for the help

Kevin, Will take some pics Tuesday, seems one of my rats have taken the camera. Will put out some cheese to try to catch them when they show up after holiday.
Thanks

Does it show Fanuc 0 above the CRT?
The system 3 on power up usually shows 3T, the model letter and s/w version # with NOT READY at the bottom left.

Al , will have to check in morning again. Gave up and started to play with the Wasino. Bad batteries on that one, have to make up packs tonite at home and try power up in am. Good news on the old one, it actually has all the parameters on a sheet from 1980 from the last change. Do the servo amplifiers or drives look for an input from the cpu to say "all clear to start" or do they put out an output to the cpu that says "i'm ready" ? not trying to be stupid just trying to go backwards to the cause.
Also found the ladder logic for the Tsugami. Will try to run through to see if I can see a stop point in the rungs. Maybee a safety I am overlooking?
Thanks for all your time!
