Yasnac 2000G RS232

[Davidgil]

We have an old Miyano Miyanomatic CNC-6BC with a Yasnac 2000g control on it. The control has a tape reader and a 25 pin port that I believe used to interface with a Facit tape puncher. I was thinking it would be nice to make use of this machine, and if I could some how interface with it through RS232 I could talk them into getting MasterCAM lathe and ...happy days . So my question is this, is it possible to interface with this control through RS232 in its current 1980 configuration, or will I need to buy a BTR card system or something? Anyone have any experience doing this?

Thanks very much in advance for any insights.

Yasnac 2000G. Man it's been a long time since I played on one of those. However I am of no help to your question. All we ever did was paper tape in and Facit punch a new tape if any changes were made.

We have a Mori-Seiki SL2 with the 2000G [bouncing ball] and a Mori-Seiki SL4 with the 2000GII [with CRT] that both communicate through RS-232. The guy that's been here since the machines were new says they had to put a card in the machines when they dumped the tape reader but he can't remember what it was exactly. The communication works fine although the baud rate is low [1200].

Thanks for the replies. I was worried I'd have to put a card in. The ones I found are about 2K.

Thanks again,

I dont know if this will be of any use but the manual for 2000g control can be downloaded free of charge from yaskawa web site. They actually (believe it or not) will provide technical support over the phone.

 

Worst case e-bay a tape punch.

While this thing is older than dirt it is closed loop, follows orders and has real time diagnostic output. While I still curse the day I offered to help my freind with his, if you manage to get it going I can e-mail you an operational procedure for a Mori Seiki SL-2. [email protected]

 

Best of luck

Mitsubishi still has the manual for download for the old DC spindle drives

Thanks very much for the info C.B. Your worst case senario of buying tape off ebay is actually sounding pretty good.

Thanks again,

David,

 

I have been working with a Mori SL4 recently and it is configured the same way. I haven't been able to send data both ways yet (to machine doesn't work so far). But here is what I have found. There is a parameter (#59) that has to be set in the control to X=3 and Z=13774 (for a baud rate of 1200). In order to change this (and any other) parameter you must set the roller switch located next to the tape reader to 1. Make sure you set it back to 0 when finished or the lathe will not operate. Somewhere I found that the setting for you communication software must be set to even parity, 7 data bits, and 1 stop bit. The pin out on the cable is a little "unique" in that it uses 15,16,17,18,19 to connect to 3,2,5,20,7 respectively.

Please, let me know if you find anything further.

[Davidgil]

Rdowns, Thanks very much. I'll give that a try today and let you know if I make any progress. Have a good day,

David

Hi,

 

Great info rdowns! The above info assumes a DB25 connection on the computerfor the RS232 port(remember the old AT/XT computer serial port that was a DB25 male?)

 

The pinout on the machine is:

15 SD (Send Data or Transmit)

16 RD (Receive Data)

17 RS (RTS)

18 CS (CTS)

19 SG (Signal Ground)

14 FG (Frame Ground - Shield or Drain Wire)

 

One other thing of note on the 2000G controller - parameter #82X selects between (0) for EIA and (1) for ISO. If all else fails on the RS232 side then tape emulation can be accomplished easily with a sanyo denki style BTR (Behind the Tape Reader) board.

 

Regards,
