Thanks scooter for the info.

when you say PS1 do you mean CP1? because I don't see a ps1 or a PS1A anywhere.

Thanks for the foam link, I will definitely get some of that.

Thanks Scooter for the suggestion, I did check that fuse originally, unfortunately it is good

Hi all

working with a Fanuc R30iA controller Fanuc R2000iB/150U

I recently posted an issue where the PSU board Failed, and I have 2 suspicions for why it failed.

one is: I am taking 230vac from CP2(which happens to be where the external door fan gets it's power from)to power a 24vdc power supply, it draws a maximum of 2.2A, but I am only powering 2 light curtain modules, so I imagine its not pulling a lot. So should I not be taking power from there? Could that be the cause of the failed power supply? I did notice on one of the other robots there is also a 24vdc power supply but it is taking its 230vac from CP1A instead, maybe I need to switch it over as well?

the second suspicion is: the controller was fairly dusty/dirty, the sponge cover at the bottom where all the wires come in is missing, and it seems to have a lot more dust in it than all our other robots. So maybe that's what caused the failure?

Any insight is appreciated. thanks.

I have found the problem!

turns out the PSU Board is bad, I swapped one in from a working robot and the fan and everything fired up almost right away and everything works perfectly again, so I will be ordering a new one.

thanks everyone for the replies, very much appreciated.

thanks guys for the responses.

The fan spins very well by hand, and since there is no power at the fan I don't think the fan is bad, I did check the 2 fuses on the board above it where the teach pendant plugs in, and they are ok. when I follow the power cables for the fan they run into the PSU at connector CP2, so I am curious what activates that power to turn on? could it be the software is corrupt or should that fan turn on pretty much as soon as I turn on the power, regardless of which state the software is in. Since the pendant was frozen originally I am thinking that is a good clue. I am assuming the emergency card is the one just below and behind the main circuit breaker(below is a picture of it)? I don't see any fuses on it.

let me know if you have any other idea to try.

thanks

Hi all

I am working on a Fanuc R2000ib/150u robot, R30iA controller.

This robot has been working flawlessly for a while now, and recently I picked up the teach pendant and noticed it was frozen, so I manually cycled the power. Since then I have not been able to get it to boot up. I noticed when I turn on the power that the external fan on the door doesn't come on and there is indeed no voltage there, everything else seems to power up. Attached are pictures showing the teach pendant state where it gets stuck, and the CPU state. I can get into the maintenance mode on the pendant, I did a ram test, all seems good, and I took an image backup just in case. I have checked a bunch of random fuses and have not found any issue yet.

So does anyone have any idea what else I might check?

thanks in advance.

wow thank you beanluke, I had a feeling it was something like that, I will definitely keep it in mind so I can use the card in the future.

Thanks Nation for the response. I am wondering if I have it setup the same way as you are thinking, My understanding is that the robot should just pull the programs as it needs them the way I have it setup(the CMOS and SHAWDOW settings), I have a second robot setup the same way only I am pulling the programs from the CF card, and that seems to be working a lot more reliably, Attached are 2 pictures showing my settings. Does it make sense to run the code you suggested the way I have it setup? or do I need to change my settings?

Hey Guys.

I am working with a Fanuc R2000ib/125L robot with R30iA controller, I got the option to load programs from external devices, and am pulling them from a NAS that is connected directly to the robot with ethernet. Everything seems to work ok, except sometimes when a program gets called that isn't "loaded" into the robot yet, I will get an error message, usually just hitting reset and start again will successfully continue the program because calling the program loads it to the robot. Sometimes though the robot tries to load the program from the NAS and just hangs up for a couple seconds, and then the program just disappears, and I have to reset the controller to have it pop up again, then I can just select it manually so it gets loaded, and then have the program call it.

So I am wondering if there is a way to "load" a program before I call it, I do have Karel so that might help.

any help is appreciated. thanks in advance.

Update on this issue.

I got a new 16-bit card and also a 12-bit card.

the new 16-bit card acts the same way as the previous one, however the 12-bit works perfectly! It starts at 880 and ends at 220, the count doesn't reset multiple times through the sensors range.

So now I'm really curious, why this is happening with the 16-bit version card. Does the robot know its the 16 bit card as opposed to the 12?

turns out the 12 bit card gives me enough resolution, so I will keep that for the project.

HawkME thanks for all the suggestions, maybe you are right and I will just have to buy a new one.

hermann yes I have tried 3, 4, and 1, maybe I should try the last one and get a new card if that one is acting the same.

I did try voltage with a signal generator, wired like you said, and the results were very similar to what I am seeing now, it counted up and reset to zero about 7 times instead of 3 times with current.

Unfortunately I don't have another card to try, I bought this one brand new on eBay.

this is the 16 bit version of the card, does this affect anything maybe? I might not need the high resolution, what I am after is a higher refresh rate then, when I had it run through a siemens PLC into the robot using group inputs.

Below is how I wired it. I even added the FG2 to ground.(except its wired to input 3 not 2 at the moment) adding FG to ground doesn't seem to make a difference though. when I look at the variable you mention I see it is already set to true. which is odd, because I thought I had configured all the IO myself.

So I connected a little analog signal generator(model SG-002), and it acts the exact same way when I have it setup as 4-20ma, but when I change it to 0-10v and wire it accordingly, it also counts up and restarts the count at 0, but with voltage it counts up and resets 7 times, as opposed to 3 times with 4-20ma. maybe this can help narrow down the problem.

also I did a test where I measure the voltage between V2- and I2+ and it starts at 4.4v and ends at 1.1v as I move the sensor closer, and it appears to move perfectly linearly. also I did an amp reading and it started at 0.005amps and ended at .018amps with my volt meter, which is 5-18ma with a proper milliamp reader it would probably come out a little better. I also tried the channel 3 instead of channel 2 and it reacts the exact same way. so what could I be missing? configurations maybe?

Thanks HawkMe for the reply.

I added a wire from 0v on the 24v side of the power supply to the Cabinet Ground, and also a wire from there to COM2, and it still act the exact same way. is it possible something is configured wrong? all 4 analog channels show up in analog inputs.

So when I wire it up like DaveP said, buy without the resistor, the count on the teach pendant starts at 1749 and then counts down to zero 3 times(and restarts at 4096), and then ends at 3538.

nothing changes when I connect V2- and COM2.

the power supply has no ground on the 24v side, so I don't have it connected to the FG2.

I know the sensor works because I had it connected to a siemens 4-20ma input module and it worked flawlessly.

Below is the schematic with the notes underneath visible, maybe that will tell you what I am missing.

Thanks DaveP for the help.

I wired it up like you described, except I used a 220 ohm resistor since that's what I had on hand. but now when I watch the readings on the teach pendant, I get about 2428 at the furthest distance, and it counts down to 0 after moving closer by only about 1/4 of the distance, and then it jumps up to 4096 and starts counting down again as I move closer ending at 1645 as the closest reading.

so something is still off. Any ideas?
