Need Help!- Newbie to Citizen and bar feed programming

[gizmo_454]

We just got in about 2 weeks ago, a Citizen E32. I have been trying to figure this thing out. I am trying to follow the books as to how to program it. the books, however, are not always clear and tend to omit important information.

It should be known that I am not a newbie to G/M code programming. The basics I do understand. I have my first program written for it. But I do not know how to get around the barfeed issue.

My problem in this case is how to implement the barfeed process. There is a small section showing in the book a "sample barfeed program" but how does it work? Again, I understand the concept of the barfeeder, but how is the code integrated into the part program?

Also, I came in this morning and turned the machine on, only to find it throwing alarm "EX001 Thermal Relay Alarm". Can anybody give me an idea what that is? I do not have that alarm listed in any of the literature that came with my machine.

This will depend on the barfeed being used. In most cases the machine waits for an end of bar signal from the barfeed, then executes a sub-program that changes the bar, then returns to the main program and re-starts the machine. If you are trying to learn about this thing and never had any CNC Swiss experience, well.....lets say it can be done, but it might take quite a bit of time to figure it all out. All the Citizen books I have seen are written in Japenglish and should be translated. You may not be a newbie to programming, but Swiss machines are quite a different animal, as you are no doubt finding out.

As far as the alarm, Citizen has a list of alarms that are not included in the books for some reason. Unless you find someone who has had this come up before, you might have to call Citizen and ask a field tech.

Good morning. Thank you for your reply. The barfeed we have is an FMB Mini Turbo S. As far as I can tell, your scenario with the machine waiting for an end of bar signal appears to be correct. I have seen the sub program in the book that corresponds to that. As I mentioned before, I am at a loss as to how that sub program integrates with the program itself. Based on what they show in the book, it will run every part. And that doesn't make sense based on the way the barfeed and machine interact.

If anybody has a sample program showing the barfeed sub program, I would appreciate it if you could email it to me.

Thank you for your help,
Mike

check your ols1 and ols2 and see if they are tripped ,if they are then reset them

[gizmo_454]

Thank you for that! OLS1 was tripped. It must have been too cold in here the other morning when I turned it on. I'll have to see about getting it an electric blanket to keep the machine warm and cozy during the night so the oil doesn't thicken up too much. LOL

All kidding aside, thank you!
