[SGARCIAM]

Maybe a password problem But we tried ABBP, drives power up correctely. But when we try move any of the screen functions we get a message,
FUNCTION NOT ALLOWED. Any suggestions ?

Hi i run an 8400 mp everyday and i turn it off every night and it dont lose its parameters even with the batteries out it does however lose any programs you have stored you might have another issue but anyway go to: support/ amp/ control parameters and you can put them in there if however you have somehow lost your pal your going to have problems if you really need help give me a call at 12173702508 and i can go out in the shop and walk you through some of it i have one at home as well and both machines have almost the same setting as far as gains and multipliers for the drives.

Thanks do u have a example of what the parameters look like to see if I have a hard copy

[miran70]

all are right except the computer save and send settings ill check the ones at work i have a picture of them there

I'm lookin' for a schematic or three...

Here's the problem. Boss's pet machine has decided that it has a problem with the X limit switch on one end... Local techie guy traced it back to a relay like Digi-Key - CC1202-ND (Manufacturer - IDC-5) that is accessible via the front door, lower right portion of the control. Well, sort of... The bad relay has been replaced, still getting intermittent shutdown due to the error.

Ideas?

[miran70]

well mine does the same thing until it warms up. if i wiggle the relay the little red light comes back on like its suppose to and it works fine then seems like when its warmed up it stops that and will run for hours with no more problems. I am beginning to believe the board that all them relays plug into has a trace problem or a connection problem where the relay plugs into well actually im almost positive thats what is wrong you might want to remove that board meaning just take the screws out and look at the traces behind it and on the front to see if there is any problems. Since your still having the problem with a new relay i doubt it was bad i bet its that board it plugs into i see some on ebay from time to time. BTW i assume you already checked the micro switch to see if its sticking or its faulty in anyway

crap Scott i just tried to call i forgot you guys are an hour ahead of me its running great im happy as hell with it like i posted only problem is when you first start it up it gives you a little problems but after about 10 minutes she will run all day. you know i just thought of something it only does that when its cold outside and i don't keep the shop above about 50 deg. i hope you 2 are doing well and i hope the shop is plenty busy. ill try to give you a call tomorrow got a few things to do in the shop tomorrow morning have a good night, and ya ill take you up on the manual and any other stuff you still have for it. if you need ill send you some cash to ship it for me.

Hey guys, I am looking for the 8400 manual as well. Mike, I have a call into someone who is working on finding/ scanning a copy for me. Lord knows Rockwell wasn't any help. If I get it I will post an update here. If you have already found it please let me know.

P.S. picking up all the drives, boards, and the controller of a AB Bandit next week for replacement parts, everything looks the same physically other than the name, didn't really check compatibility cuz the price was right and I'm sure I (or someone else) could use something at some point. If anyone is looking for replacement parts let me know. I like to trade.

I bought a shizoka ANS mill some time back and have all the manuals scanned for the 8400 & the 7930 drive package if you PM me I can send to you.

I need a little help getting a replacement servo motor for X axis. If anyone can help it is an AB 7900 series motor Catalogue# 183-18-1420-0. It is made by By H.K. Porter Co. Dont need this specific motor. Just something that will work with the 7930 amp card. Any help would be much apprciated.
Maybe if someone is parting a bandit mill out let me know what you want for a motor. I can post more info on shaft/frame sizes etc if need be.
