Thread: Need Help with 1007 Alarm on Yang SMV 1000

Hi All

Hoping someone has seen this and can help.

Machine is a Yang SMV 1000 with a Fanuc 0-MD

I have a 1007 alarm wdescriptionpotion of "Mag CT1 NE Ct2"
The Alarm resettablesetable.

I found some info on the net saying check diagnostic 455 and make it the same as Diag 457. I had 0001 in 455 and 0000 in 457 so changed it to match.
Fanuc is saying this is a Yang Alarm. I cant find any alarm info on the net and cant find anyone at Yang that will return my calls.

Some googling for "Yang alarm 1007" leads me to believe it is a tool changer alarm. I would manually reset the tool changer. Of course I only know how to do it on my Kitamura with a Yasnac control.

Thanks for your reply.

Yes there is a red led on the control with ATC lite up (Automatic tool changer).

I am a CNC tech but work on Punch presses, brakes, Lasers etc. Am a bit out of my element with this machine. Just trying to help them out.
I toggled all the air cylinders and everything moves, All the Prox switches are switching on all related parts.
Customer bought from an auction and has little to no info.

I think you need to get the procedure to reset the tool changer arm, that will probably most likely be machine specific and have to come from Yang.

Anyone know how to get a hold of them? I tried calling, they hung up on me. The next time I called they said a tech would call me back, never did.

I found a company called Spectro USA on another forum that claimed to be Yang support for USA, but the post was 3 years old and their phone number is disconnected. Also not your model, but I found a post for tool change macros on a Yang with a Fanuc Om control. It was about a few dozen lines long. I find it hard to believe a machine would need more than a simple M code to swap tools. Sounds like they are goofy machines and have next to no support, good luck. There is a forum member that I know that I believe has a Yang lathe he rebuilt, I don't know if he has talked to Yang, I will check with him tomorrow.

You would think that machine tool builders would have learned better than that by now. One guy gets hung up on by Yang and left to fend for himself and it will show up on the internet for years to come and most likely cost them some machine sales down the line. I understand not wanting to spend a lot of time supporting a machine that they are probably never going to make money off of again, but at least offer to sell copies of the manuals and maybe even some $100 an hour phone support. I am sure that someone over there has a copy of the tool changer reset procedure in pdf that would not kill them to send out.

A perfect example of why not to by an "off" brand.

The alarm description would lead me to think that there are two counters in the PMC that are not equal. For example, one counter holding the "target" position of the magazine, and the second counter holding the current position. At the successful completion of indexing, they should be the same. You said that you made them match. What does that mean, you made them both 0 or you made them both 1? What was the last position commanded? (If it's a fixed-address mag, then the last T-code. If random-address, then the mag pot that corresponds to the last T-code commanded. If you made them both 0, did you try making them both 1? Vice versa.

How does the mag sense its position? Prox switches, encoder, etc?

THX everyone!!!

I changed to both Zeros, didn't try ones.
I did find a section with machine Diagnostics related to the tool changer. It mentions how Diag should be 1 in T1, 2 for T2 etc. Both 1 and 2 were 1. I also seen that 99 was a valid entry. I see 99 in the #1 diag and also in another example in the #2 spot which confused the hell out of me. Maybe the Diag switches to 99 when at the tool station??? it also mentioned something about a MDI command using 99.

I can get a copy of that page if you would like to see it.

As far as command I’m not sure. The program was using t1 and t2 from the looks of the G code.
Sounds like a lot of different people have been messing with this thing. When I got here the Fanuc I/O board was GONE! It’s a messed up situation, no one seems to know where it went.
With the I/O out there was not a single alarm other than the 1007. I was amazed. The Mode switch wasnt working and I traced it back to the I/O board. That was the only way I found it was missing. New I/O was installed by me and everything seems to be working correctly other than this 1007 alarm. The Tool changer has limit switches for in and out movement and has three prox switches for rotation. I spun the tool changer by hand and all prox switches are toggling.

This machine is new to the customer (bought from an auction) and was running. I'm told they had a tool collision. That is how this all started.

Thx again for all your help.

Yang, YAM, Cadillac. All the same manufacturer of Taiwanese machines.

In my Rolodex: YAM 562-222-1808

Tex Tech, Hico, Texas: 254 493-8975 Sort of a rep for Yang.

Web: YangMachines - CNC Machine Tools Company - Yang Machines 562-777-1111

It is my understanding that in the early nineties, Yang went bankrupt, then reorganized and is back in business. My dealings with them have only been for several Cadillac manual lathes. It has been 5 or more years since I last dealt with them.

Alphonso, I think you can throw out that Rolodex card, that (562-222-1808) is the number I dialed yesterday that has been disconnected. The guy I thought had a Yang had a Kia, but looked at a Yang when he was shopping for a VMC.

thank you!!!

I sent an email, will let you know if I get a responce.

Being in Canada usually doesn't help the situation. Lots of US dealers are forbidden to sell/talk to or sometimes even service any machines up here, and with certain brands its not uncommon that who the rep/dealers is up here can change twice in a year. Some US dealer tel #'s are blocked outside the US as well.
Could well be why you got hung up on. Some brands aren't worth touching.

Well said. I've been scoping out gang-tool CNC lathes and have come across a couple Yangs. I'll be crossing them off the list!
