fanuc machine--- tape and drill mate model t 1990 fanuc omc control

mistake # 1 changed back up batt. power off--------

power up---reset xyz to home manually as per instructions on screen

all went fine machine and control work fine EXCEPT for tool changer

t(x) mo6 will call up tool change program and will preform a tool change but will not rotate the carocell

because the z column gear falls short about 3/8 of an inch of meashing
with the carolell gear than completes the tool change action

this is the only thing that changed

it sounds like your parameters survived, but you probably lost the 9000 macro(s). problem cant be fixed easily without a backup.
contact machine manufacturer or Fanuc. or find someone with identical machine and get backup of macro programs/parameters from them.

[planejerry]

thanks for the reply--------the tool changer is working to the degree that the z column moves up into position to change tools---- but short of engaging the gear

to turn the carousel---the tool change gear on z column rotates--- then the z column returns to home and continues with the program

if the macro was gone i am thinking when it came time to change tools the machine would alarm out ????????????

[fordav11]

did you check your parameters? are they still ok, including the option parameters?
seems very strange. maybe you have some mechanical issue that just happened at the same time. maybe a stuck switch or something?
did you have programs in the memory and were they lost or still there? if they were lost then for sure you lost a macro program. if they were still there then it could be a mechanical issue (assuming your parameters are still all ok too)

[underthetire]

did your tool offset move about the same amount? im guessing z returned in the wrong spot.

and was this the servo backup battery, cnc memory battery or both.

To see the 9000's macro's you may have to turn on bit #4 in 0010.

hi guys thanks again for the reply--------

both sets of batt's were changed at the same time ---------- what might have saved the parameters is, i changed them very quickly (maybe the charge on the circuit had not gone down to far)

i have run several programs in memory after batt change. the machine runs fine except the carousel does not rotate

the z position may have changed, but when i set a tool off set down from z0 i get the correct distance to machine the part

if i turn on bit #4 in 0010 to see the macros

how and where do i look at those programs

[fordav11]

when you turn off the 9000 protection, you will see those programs just like any other programs. you can view, edit and delete them just like any other program.
if you do see any make sure you punch them out and keep them safe.
when you've done that change the protection parameter back to its original setting so no-one accidentally deletes them.

thanks for the reply on the 9000 topic i will try that

this machine is simulator to a robo dill cnc ----its tool changer carousel is facing the operator

i have run several programs from the memory after batt change. the machine will run and preform a tool change except the carousel does not rotate

this is because the z position needs to move up another .400 to engage the gear that rotates the carousel

this is the only problem that showed up

i am wondering how this distance or measurement changed --------- and how and where to change it back to be correct

thanks for your help

the carousel does not rotate because it has to move up another 3/8 inch to engage the gear that rotates it

[fordav11]

so it is possible to manually move it up another 3/8"? or will it not physically go up that far?
is it the zero-return position or is it higher than that?
if its the zero return position, you might just need to re-set the position. manually move it up to the correct position then in parameter 1815, toggle the Z from 1 to 0, then change it to 1 again. power off/on and that will re-set the Z zero return position to the current position.

[planejerry]

hello again

i sounds like you have come up with a good solution

just so i have it clear about the procedure

1-- power on----- 2-- home xyz----3---set pwe to disable go to parameter 1815 set to 0----- 4--- move z up .400--------5---- set 1815 back to 1 and pwe enable

5 power off ---- power on home zyx to new z0

[fordav11]

almost. and ONLY if the tool changer position IS the home position (some machines go higher to do the index so this wont fix it)
1-- power on
2-- home xyz
3-- move z up .400
4-- set pwe to enable (i.e. 1)
5-- go to parameter 1815 set to 0, then set it to 1
6-- set pwe to disable (i.e. 0)
7-- power off
8-- power on home zyx to new z0

[planejerry]

ok thanks again for the return,

so far------- sence the machine still is working, i have not tryed to change anything or go into the parameters.

i screwed up once!!!!!!!!!!!!!!!!!!!!

what about trying a o cancel ? pressing and hold o and cancel while power up.

what would that do if anything?

also i have read about mdi g0 g91 g30 x0 y0 z0
this is suposed to be a secomd x0, y0, z0

what is the secomd home used for?

i usually home with mid g0 g91 g28 x0 y0 z0.

Sounds to me as though you have lost the grid shift for the Z axis?
This is parameter 0510 GRDSZ.
Do you have the parameter manual for the 0M?
Al.

[planejerry]

i have downloaded what i think is a fanuc omc manual

however in the one i got there is on 510 parameter and many of the machine parameters are not listed

i have taken a complete set of photo of the parameters on the machine however this was after the batt change

there is a parameter 510 set at -50 on the machine

if you know the correct parameter manual could you send me the link or that info?

thanks jerry

[Al_The_Man]

You would need to send a PM with email address.

[fordav11]

The 2nd home (G30) is just used to put the machine somewhere fixed instead of having to G00 there.
For example you can put the XY to the opposite corner of the table for a tool change on a machine where clearance between tool and job is limited.
I missed the part where you have a Fanuc 0. The parameter to change is not 1815.

[planejerry]

hi guys

just a recap----- this is a fanuc omc control on a fanuc tape drill mate model t machine 1990

may have lost some parameters do to changing batt

can anyone direct me to the correct place to contact or call for the parameters for my machine

thanks

jerry

[fordav11]

you may be in luck. see the last post....
