Need Help!- FANUC I/O

[gbowne1]

I've been trying to sort out some issues I've been having with sorting out all the I/O involved on my builds.

With the 16MB, I'm having problems with my Allen Bradley 802X/802T limit switches that I've been using on X and Y, especially when I use G28. The Z limits are fine. The encoders are fine, as far as I can tell. It seems to be an intermittent problem. I used the A03B-0807-C001 ABU10A base unit. Since I don't have a proper 802 limit switch wiring diagram (anyone got one?) I hooked it up based on the setup I have on my 15MA. Anyone have comments on using Linear scales on these machines?

With the 16MB, I'd considered using one of the A03B-0815, -0817 or -0819 I/O units. I just went with what I'd seen on other 16's.

On my 10TF, everything works fine but the spindle & way oil lube pumps, one of the X/Z limits, What's labeled as Y seems to be ok, and I'm trying to sort out the issues with M19 orient. The spindle servo and all of the amplifiers are freshly rebuilt 10/2011. I'm just now getting to the tool change macros. I've never done tool change macros on a lathe. It's an 8 tool turret. I used the A03B-0801-C012/-C013 base unit here. The op. panel I/O seems to work fine.

The 6MB2 is pretty much finished as far as the boards go but the I/O has to be finished up. I used the A02B-0051-C540 Option Unit and the -C693terminal unit attached to the two I/O boards here. I've based my build here on the I/O chain I have seen on other machines with the same control. the machine is in my shop awaiting the control.

Any comments suggestions etc. appreciated.

What application are you using the 802 Safety switches in?
Here is a operation pattern for the N.O. N.C. contacts.

I'm using the limit switches as the X and Y limits for the table. Probably not the best limit switches to use. Especially for the overtravels.

Here's the ones I used:

Oiltight Limit Switches

Someone gave me some OMRON WLCA2-2 Limit Switches that I didn't use. They were the type with roller rocker arms. I might use those with the other VMC build.

Just to be sure I've done it correctly, Where are these wired to when I use the A03B-0807-C001 with 10 modules installed. I can tell you what modules I have when I look tomorrow. I have some reserved for the 18iMA build. I bought one each of the 25 different modules both the analog and the digital ones.

The Way Oil on the lathe is coming from a Bijur CESG-3L for now. Couldnt find that wiring diagram either. Until I can find a more suitable solution... It's not working at all now but it was tested working just a short time ago.

The switches on the VMC doors work fine though. They are as the document you sugggested linked too, except the switches are a little different.

My favourite is still the Honeywell 914CE2-3 series.
See roller plunger.
http://sensing.honeywell.com/index.php?ci_id=49970
Compact and hermetically sealed.
They come up on ebay all the time.

Can't beat the old SL1A's if you ask me. Cheap and easy to replace if they fail.

This price is crazy though. All world has them for about 25 bucks each.

Well I am gonna try your honeywell switches. Fortunately I live not far from a industrial automation supply place. Anyone have wiring diagrams

Well, as for the 10TF lube pump, I figure that it must be a timer, keeprl or counter issue because I've seen the unit working properly before it was installed.

As for the 10TF I/O there, the unit I used is a A03B-0801-C013 type with 10 slots.. the modules are:

1 ea. A03B-0801-C140 OD32A
2 ea. A03B-0801-C123 ID64C
1 ea. A03B-0801-C141 OD64A
1 ea. A03B-0801-C104 IF01D
1 ea. I/O power supply A16B-1310-0010-01

Panel pic is as shown befor I was ready to install.. although I can change out any of the modules as I bought just about one of every one they ever made. I just don't know a heck of a lot about the IF01's..

As a side note a friend of mine asked if it was ok to interface a FANUC 90-30 as a external PLC on something like a 6M or an 11M.

Just have to sort out the 16M's I/O and the limit switch problem which seems to be intermittent.

The wiring is simple contact closure switch, N.O./N.C. to a common and a ground wire.
It looks like you have the remote PLC rack type of I/O rather than the simple single I/O board set up with Honda connectors.

Yeah they are the remote type, after reading much of the FANUC manuals I've collected, these are the type suggested by the maintenance and connection manuals. I just got lost as to where to wire what wire. especially having no i/o wiring diagrams to reference. My mentor that had been helping me locally left the state.

so, not having that level of help available I've just been going over what work he's already done for me. I've also got the wiring diagrams of some similar machines that use the same control to use as a reference.

whats the issue with the lube units? there is a PMC timer setting to turn them on every x minutes and a timer for how long to stay on in x seconds. if your settings are 0 then it wont power on.

[gbowne1]

I have no idea other than the motor doesn't run. From what I've seen in diagrams I found, the unit is hooked up properly. I have not begin to set up and inspect the timer settings. What needs to be done here? This is on the 10TF.

[fordav11]

it wont run if the PMC doesn't tell it to run.
I don't have 10-series PMC data but on 16T this is how it goes.....

R values are the ladder addresses. Values known are in bold

Variable Timers
T02 R300.1 Lube pump OFF time not during automatic operation
T04 R300.2 Time for monitoring dog of lube pump ('dog' might mean level or pressure?)
T28 R301.6 Time for lube pump ON time

Fixed timers
T02 R305.1 Time until start of counter for lube pump during automatic operation 1500ms
T03 R305.2 Time from lube pump OFF until lubricant pressure check 60000ms

[gbowne1]

Thanks for the timer data, fordav11. Would it be the same for the 16M Model B. I'm taking a guess that the problems I've been having with the limit switch are related to one of the 3000 series parameters.

anyone have good PMC data for the 10TF?

I have been busy but I need to look and see what I/O modules are on the 16MB.
