Ohh thanks, that helps.. my AB8400 drives work fine so ill use those with the Chinese control i think, but will replace them if they give trouble. Not sure how accurate they are though

Hi, also looking at these controls, seems hard to find a website with specs etc, this would be for a replacement on an AB 8400 control. Ned to know, will it do step and direction or 0 to 10 V type...
I never found any, but know a little about it, always seem to be able to keep the old thing running I guess. It's a decent control, arc interpolation is a bit clunky though, and it's not the machine...
Sorry for all the questions, but I guess that's why we're here.... My mill has 1000 pulse per rev encoders on it now. But who's to say that I also need a 1000 pulse encoder on the 4th axis rotary...
I got this A06B servo today. Attached a pic, looks like a tach to me. I put 12VDC to two of the power terminals and it runs fine. It's quite a bit bigger than I expected, but will be nice for a 4th...
Encoders on this AB mill are "BEI optical encoder, model number E206-1000-1". BEI offered a replacement number "H20EC-25-F8-1000-ABZC-28V/V-EC18-S, -S: A LEADS B CW, Z GATED WITH POS. A, 38195-001...
I don't think I need a tach, it has BEI encoders now, but obsolete ones that I need to cross reference, think they are 1000 line ones. I will get this servo on Monday so can look more then. The AB...
Eh, that's going to suck I bet, maybe MCS.com has an encoder for it. It was only $200, now I know why, guess at that price I will be able to spend a bit more for one.
Well I ended up getting a different one. It's an A06B-0642-B005-R, in good shape I think. Can't figure out what resolution that is.
Sorry, slow reply. Thanks for the chart, very helpful. Can you tell me, how many wires are actually used from the encoder, so that aI might try to see if a similar amount are used on the AB system. I...
So, this one I think is no good with a 300 line encoder. thanks for the info. Can you tell me, what are the smaller Fanuc servos, the smaller model numbers like a 5M etc is smaller than a 6M? And...
The last stamping I think says 3000, and it is a model 5M, so you hit on it right I believe. I will look tomorrow and see if I can find anything in the AB control that says about being able to scale...
I don't have the servo in my hands so I can't look under the cap, bummer. The servo says Type A06B-0642 on the tag and then stamped 013 after that. Date code is 85 if that means anything either. I...
I am trying to drive a Fanuc DC servo, a 6M, with an Allen Bradley drive, AB 8400 system. Wondering what that servo has for it's position feedback, is it an encoder, a resolver or? The servo has the...
Thank you, I still find very few references to this control on the net or anywhere. Anything you can supply would be helpful. I am slowly finding out more on the 8400, I figured out how to run it in...
So it DOES have DNC, I didn't know, the control says nothing like that on any screens. Can you tell me what to look for, something to go on? It has only 15KB of memory and if you use Surfcam or the...
Did you find the Allen Bradley manual? I still have a lot of questions on this control, like how to DNC a program, mid program restart, etc etc. Will buy your manual off you if you are willing to...
Thanks for that. I got the work offset thing figured out, it has a Fixtures offset page, has 12 offsets. It has a setting for "Last offset" for some reason, like you can block out the last 10 or...
Thank you, if you actually have the manual and want to sell it I would def. be interested. Or, if you could even copy a page, I have a fax or something, anything would be a big help. This mill is all...
Thanks Jon, it does have G92, will see what might work there.
OK, nobody responding, it sucks when you do Google searches for info and all that comes up are your own posts in these forums! Can anyone recommend a CNC programming book, like something from Peter...
I bought a Bridgeport type Lagun mill with an Allen Bradley 8400 CNC control. It all works fine, but I have no manuals with it. I know G code well and Fanuc machines no problem. My problem is I can't...
OK, an update, the machine works fine, the batteries just had dirty contacts. Boot up sequence is odd but if you do it right all is well. I have no manual for this thing so am just going off...
Hello, first post on here. I bought a new-to-me Lagun 10" by 44" 3 axis mill, a Bridgeport type, with an Allen Bradley 8400 Control. I got the machine powered up, the drives have no power yet for...
