I'm bringing up a 2007 Citizen K16 and am trying to get the LNS 226 barloader to do a bar change. This is my first time programming a Citizen and it is a little different that what I'm used to(Miyano BNE, Tsugami BS26, Index GS30). I've completed the program and understand how both programs need to be inside of one main program. What about a sub-program? Does it need to be inside of a main program as well? If anyone has an LNS connected to a Citizen and could share the code for the bar change, it would be greatly appreciated.

Thanks

After the cutof routine you should have this;

^ looks good and yes your sub-program needs to be in the main program just have to call it up in the main program when it detects the EOB.

Thanks for the help so far. I tried to put the sub program in the main program and I got 5010 end of record alarm. I put it in the program directory and it found it. When I get to M55, I get a 0112 zero divide alarm. Fanuc manual says an attempt was made to divide by zero in a custom macro. Any thoughts on that?

I didn't think M55 would be dividing anything. You don't have any strange values anywhere, or any other code on the same line as the M55 do you?

No. Even if I MDI M55 I get the same message. M54 works, M55 gives the 0112 alarm. Really strange. I tried the M108 macro and it just sits there and does nothing. All the while the phone keeps ringing asking when it will be running!

Can you post your code on here maybe some more eyes can see whats going on.

I just took this from the control. Basically a test program so I can get the bar loader parameters set. There is no material in the machine. Works until it hits M55, then the alarm.

Just a second thought the last few LNS barfeeders we have gotten have had bad wiring issues, to the point where we had to run the machine with the loader disconnect on so it would EOB correctly. Might not be a bad idea to call LNS and have someone come out and take a look at it.

try running that program with the loader disconnect on and see if that works

If you are talking about disconnect in the operators panel, it is set to 1. If I set it to 0 it alarms.

Then I have no idea. I think put a call into Citizen see if they have an idea or call LNS.

There were sofware problems with certain barfeeders. Call your Citizen distributor and have them check your version of software for that feeder.
