We have an Okuma Multus B300 with OSP-P200L control. I need to mill a pocket on the OD of a turned part but the OD surface is tapered 10 deg and the pocket floor is parrallel to the 10 deg angle. Is...
Just bought a 2003 YCM Supermax TC-26L turning center with a Fanuc 18T-C control. We are getting a couple alarms when trying to use the tailstock. Tailstock is programable, ie move to position M124...
I have a 1990 Fanuc OT-C control which will accept man readables (COMMENTS) but I can not edit or add any at the control only on the computer before sending to the machine. Is there a parameter that...
Found a cable plug wire that had broke off one of the pins that goes into the encoder, soldered it & we are up & running :)
Thanks for input people, much appreciated
No he didn't Al. We pulled the encoder off the machine & brought it into the city.
Ya machine was running fine before we changed the spindle drive belt & ran briefly after putting new belt on. The electronics tech guy tested the encoder & says he's getting all the correct...
ok we had the encoder checked & the electronics tech said it was good, was getting signals from A, B, A" B" something like that. Guess we need to start tracing wires back to cabinet ?
Also we can put it in dry run & vary the feed that way but not in manual jog or automatic, it just crawls along. Is there any wiring that runs from the encoder to the spindle ?. Just wondering if we...
ok checked the machine last night. The spindle speed will increase & decrease in manual or MDI mode G97, input S200 & spindle seems to be going 200 rpm, input 500 rpm & same thing. But spindle speed...
ok will check that out tonight when home. This machine sits at a friends property, not at my workplace.
well the belt didn't exactly break had to cut it off, all the drive teeth are basically gone.
Fanuc Spindle Encoder Problem. Not sure if this is the right forum for this, if not let me know where, please & thanks.
Have a 1990 Leadwell LTC-20CP 2-axis slant bed lathe with Fanuc OT-C...
We ended up calling in a service tech. He had everything up and running within a few hours.
Jumpered the the air to turn the alarm off. Now the machine can move & be sent to home position....
Thanks Beege I just bought a lathe that had 4 Macro A progs in it now I have a better understanding of whats going on, they're for the tool sensor arm, which no longer exists on the machine. I do...
Good day, well we got our new EPROM chips from the machine tool builder installed them & no more 998 ROM Parity error & we were able to input all the parameters. But now we have some other alarms &...
Ok finally had a chance to mess with the machine again.
Tried to input the DGN parameters no luck, no key for program protect so removed switch & connected the 2 wires, G122.3 did not change from 0...
Thanks cnc2149. We will turn the program protect key to on & try again tonight. The G122.3 is this from the ladder logic ? I included a couple pdf's from the parameter manual 61400e
19.7=1 decimal input was already set as was 38.3=1 full key board, PWE=1, emergency stop on & still would not take the DGN parameters. In our parameter list, they are listed as D300, D301, etc up to...
ok we will give that a try tonight, thanks
ok gents we managed to finally get most of the parameters into this old girl, after many attempts. Would load parameters shut m/c down fire it up & get 998 alarm, clear memory & re-enter param's....
Thanks humak16 I think I should be ok on inputting the parameters, one question in my hard copy parameter list I have D300-D??? these would be the 300 series parameters, in control just show up as...
ok made an un-scheduled visit today after work to where the machine sits. Checked all plugs, boards & the ROM/RAM chips on memory board if loose, all seemed good. Powered control & got same screen...
ok thanks humak16. We are going to check for loose boards or chips first. Then will try dumping the memory & reload parameters. I emailed the previous owner & they do not have back up copies of the...
sorry wrong link to memex, try this Manuals
Thanks for the replies. Can't back up the parameters because you can't get past the alarm screen it comes up as soon as control powers up. I sent an email to the previous owner & hope they have a...
Thanks ker2008 for the reply. Now is that on the memory board, main board, else where ? & how do I find it ?
ok a bit more info on this machine.
main board A20B-2000-0170/02A
MEMORY BOARD A16B-1212-021 with a small square & then a rectangle ?? could be a A16B-1212-0210 ???
series OTF
software version...
Hi Andy thanks for the reply. I am lacking experiance with the electronics side of cnc machines. How do I check the 5v power supply ?, is this the back up battery ?
Just bought a used 1990 Leadwell LTC-20CP lathe with a Fanuc OT control. Just powered up & get error 998 ROM PARITY ERROR, ROM NO 0E1, 0665-13
What is this & how to fix it ?, the manual lists the...
