Hello,
I can only move X axis in one direction with jog or step commands. It will move very slowly the other way with the pulse generator. No IPM shows as being input on the monitor in jog, but does shown with pulse generator. Think it may have lost absolute 0 so the control is prohibbiting? This uses a general numeric console with all else fanuc. Y and Z will home.I think all parameters are intact. Cannot figure out how to overide the write protection so any help there would also be appreciated.Please see screen shot of the start screen.
Thanks,
Scott

Hello
Check the desceleration switch for the X axis.

Thanks Alex, i will see if that is what the issue is. Do you have any knowledge of the early General Numeric controls on how to turn off the write protection for parameters?

General Numeric was the North American marketing arm for Siemens & Fanuc. The controls were Fanuc. You have a model 11 control. PWE is set on the SETTINGS:SETTINGS page.

Thanks for the help. I was able to get the write protection off and on again. There is no deceleration switch. Just hard overtravel and homing switches. I still think the X axis lost the O position and that is not allowing it to home and therefore nothing else can run until this is fixed. I tried moving the table until the home position switch was just activated and then operating the pulse coder to register 0. That did not work. Any other suggestions on how to further trouble shoot the homing issue appreciated.
Thanks,
Scott

[Scott Pancheau]

Thanks again Alex for all your help. I will pull off what I think is a homing position reached switch and see if it is stuck.
Scott

[Scott Pancheau]

You were right on Alex. The switch is closed all the time. I have a new one on order. Thanks so much for your help.
Scott

[Scott Pancheau]

Alex Fanuc I hope your still out there.I got the new switch in and can now home the X axis. Now I have another issue. When I first turn the machine on and before I home it I can jog the Z axis down and up. After I home it the Z axis does not respond to jog anymore. I can enter single move commands in MDI for X and Y and they work, but always in rapid regardless of the feed rate given.There is no response to MDI command for Z. The homing speeds are still slow from start to end. The DRO for machine position goes to 0 when homed, but I don't know if the X is homing in the exact right position it did before. Any suggestions on trouble shooting these symptons?
Thanks,
Scott

Please check the following diagnostics:
264
268
272
Before and after you send the machine to home.
Also diagnostics:
64, 68, 72

You have an interlock in the Z axis. DGN 72 bit 4 should be a one.
DGN 64 bit 4 is one for the X axis =ok
DGN 68 bit 4 is one for the Y axis = ok

You need to check why the Z axis has an interlock.
Is this a vertical machine?
Something is not in position so the machine will prohibit the Z axis to move . The Z axis will move when everything is ok to move.
The three axis did home ok. You can tell by looking at diagnostics 264, 268 and 272 bit zero = 1.

...if this is DATC type Tool Changer/Randum...the Tool Mag would need Homing if, memory has been cleared.

[Scott Pancheau]

It is very similar to the picture of mill posted by machinehop5. I will get a couple of pictures tonight. Is there a way to check on the tool change memory being cleared or not? I have found a maintenance manual and a programming manual to purchase online, but so far no wiring diagram. Thanks again for all the help.
Scott

[Scott Pancheau]

Please see attached pictures. There are 5 limit switches that I found on the tool changer and the tool lock unlock.After I actuated all the switches I can now jog the Z axis after homing and pushing the reset on control panel. I got the tool changer to move one time. The change arm swung to the tool load or unload position and that was the last I could do.I forgot to tell you that the CRT has always displayed an error that I think must have been the last program running when it quit the prev. owner. I can't figure out how to clear it. It says error .08073 N000000. I did clear all the g code in the program and then used it to enter the moves for XYZ. It will run the XY moves in rapid, but still ignores a Z programmed move.The spindle at some point starts to do what I think is a tool change positioning? It rotates very slowly about a 1/4 turn - pauses for about 3 seconds and rotates again. Does not seem to be affected by the position of the Z axis once it starts. If anuone has a wiring diagram for a Burgmaster VTC 150 I would love to purchase a copy.
Thanks again for your help guys.

Try to do an M19. Orient the spindle to see what happens. See if it stops without any alarm and at the same spot.

The M 19 did not work.There seems to still be somthing it does not like that is preventing the Z from accepting any move commands. I actuated the tool change functions with their relays and they all work as they should. The lock position micro apparently actuates the control to tell the orientation to begin and unlock position cancels.I realize that without any wiring documents and no real knowledge of Fanuc, I am not likely to get there. I said it always shows a program No. error, it is actually an alarm and I can't seem to get rid of it. Thanks for all your help Alex.

I think all parameters are intact.

...good point. Do you have all the MTB Parameters stored/backup/written down would be good idea before changing anything.

I see Alex helped fix the X homing issue which you fixed by replacing the SW. Without knowing the history of your machine sounds like the Tool Changer has a sticky Interlock SW causing the Z problem, try manually stepping the TC thru a tool changer cycle afew times and can of WD40....lol. Alex sounds like he would know which Params to look for TC switches.

Thanks for the idea, I will give it a try,.The WD 40 is pretty magic stuff. I have not written the parameters down and I know I need to take the time to.
Thanks Machinehop5
