086/"lsk" error on fanuc 0T controller

[endicottmachine]

I have a Fanuc OT control on a lathe,I am having a problem with the communication..I can send the programs fine but when I try to receive .It blinks "LSK".

The computer thinks that it has taken it fine,but the machine did not take the program..

Any help would be greatly appreciated.......

 

I can still send programs to the mill Fanuc OM controller and I used to be able to send to the lathe fine yesterday. The only thing I changed was I opened cimco edit with the newest version of mastercam X^2 and not mastercamX mr2.

Verify your comm especially the parity settings.

 

the 086 alarm is I believe a parity issue.

It has always given me an 086 error but sent the information, the mill has as well. My parity is set to even whatever that means and was set that way when it was working yesterday, do you still think it would be that setting? Is it a setting I have to compare with the particular fanuc controller and its settings?

I know a guy that gets that alarm also on one machine (out of three), but the program loads. He just hits the reset and goes on with the setup. The blinking lsk shows up as the program is loading and will normally quit when the loading is done but I'm not sure if the blinking quits after an 086 alarm.

I tried using the RS232 cable from the mill on the lathe and it still gives the same problem. We called machine electrical and they suggested it might be the port as well. A guy from machine electric is coming to replace it or configure the other port wed, until then I will try and keep troubleshooting the problem.

The LSK is the machine waiting for the info to send. When the file is being sent it flashes "input" I would do a loop test thru the cable and see if the cable puked on ya.

you need to be carefull with rs232 ports do not plug in or unplug while the machine is on you can blow the board, they are more sensitive them people think.

[Storkman]

within a thou is correct. If you see lsk flashing then it is not receiving any info. It will flash input when receiving.

Loop Test

Make sure you have 6~8~20 jumped out on the machine DB25 side.

 

In addition 4~5

check your communication settings in cimco and make sure they're the same as you were using before. If the control just keeps blinking LSK then it's not receiving anything and your computer won't know if it's been sent succesfully.

the cable tested good. The technical support at machine electrical tried using the backup port but it turns out the port was even worse. The board was purchased as a refurbished board awhile ago so i am not surprised. The entire board will be sent out next Monday to be fixed.
