    Easiest way is just to replace them, or swap with a known good part for testing.

    I've had the problem you describe though many times, and it was always the driver chips. Luckily, the chips are available and somewhat cheap.

    Thank you so much pdl!

    I replaced chips and it is working. I really appreciate your help

    anyone who has same issue like me, try to replace driver chip what pdl mentioned


    Hi everyone.

    I have a question about EE connector. our robot is 120ib/10l and controller is rj3ib.

    we put air solenoid to EE connector in order to control wire brake.

    picture 1 is working fine based on pin layout in manual. manual says pin1 goes to RO1 and pin5 goes to 24v

    problem is that we did exactly same setting on another robot (same model, same controller), as soon as we powered it one, solenoid is actuated right away continuously.

    never turned off. default is on which is not correct.(please see picture 2)

    Picture 1 and picture 2 look different a. it is upside down. I don't know that is matter or not.

    to summarize it,

    picture 1 is working with pin1-do1, pin5-24v.

    picture 2 is not working with same setting(I also tried many different combination as well). solenoid is activated by default and never turned off(I can't control)

    Any advice would be appreciate.

    Thank you

    Hello Everyone,

    I have M900ia/260L pick&place robot on our shop.

    I wanted to hook up multiple suction cups on the EE. What I did to our existing welding robot is that

    I connected solenoid to EE connector on the J3(5pin female) and control by RDO1(That robot is 120ib/10l)

    This robot, M900ia/260L, doesn't have EE connector on J3 or J1.(in the manual, it has 24 pin ee connector but I can't find it)

    It only has DS1,DP1 on J1 and DS2,DP2 on J3 which look like devicenet and unfortunately, I don't have any experience about devicenet.

    Can you guys give me any advice how to use devicenet in order to control suction cup?

    I just want suction cups ON and OFF by toggling bit in teach pendant. (We don't have PLC and no plan to install PLC as well)

    Any advice would be appreciate. Thank you

    What do you mean "make connection". Are you saying the fuse blows as soon as the cable is connected or when you probe for voltage?

    we tried 2 way

    1. 3 pin M8 connector to EE connector - put blue and brown wire to Pin 1 and Pin 3(just make contact end of open wire and male ee connector) - fuse blown

    2. multimeter to EE connector - make contact multimeter(set it as voltage, not amp) and male EE connector(pin1 and pin3) - fuse blown

    I am sorry if you don't understand my questions well because of my broken English

    Is your multimeter set to measure current or voltage? If you have it set wrong you will cause a short circuit and blow the fuse. If that is the case then I highly suggest you get some electrical training.

    Nope. we set it at voltage. we tried it with multimeter also, we test with new fuse and connect 3 pin M8 connector to the EE connector directly as well.(NPN blue goes 0 brown goes 24 black goes input) but as soon as we made connection, it blown.

    Hello Everyone.

    I am working on hook up wire brake(from tregaskiss) to 5/2 solenoid and solenoid will connected with

    EE connector which is on the J3(5pin)

    I bought Fujikura JMSP-1305M-D connector and connected to EE connector of robot.

    I didn't even hook up the solenoid just wanted to test there is a 24v on EE connector with multimeter.

    As soon as I made connection, fuse blown. I tried multiple times but keep fuse blown which is FS2 in servo amplifier.

    5 Pin out is that

    Pin1 RDO1

    Pin3 0V

    Pin5 24V I forgot the rest of 2 pin out

    I checked pinout with multimeter which I made connection pin 3 and pin 5, fuse blown.

    Anyone can explain what happened to our application?

    Thank you so much

    I did not have to pretest, but I have taken some Fanuc courses before this one (Handling Tool, Electrical Mtc, a mechanical class, and Advanced Teach Pendant). I do remember talking to a guy on the phone and he asked me a handful of questions about PLCs while I was registering, but I just assumed he was making small talk. Maybe he was testing me... You would do well to find out what PLC platform your company wants to go with and get familiar with it before you take this integration class because if it isn't AB, then you are wasting time and money. During the course, the instructor mentioned that they are toying with the idea of having a similar class for Siemens PLC, but who knows if that will ever even happen.

    Thanks again Duranthas.

    Can I get your email address if you don't mind?

    I might have some questions about that course in the future

    Thank you so much for the info, Sbeve2020

    I will take a look at it. cheers

    I took that class, and you really should have some basic understanding of Allen Bradley PLC & HMI products. I suppose you could walk in without any PLC knowledge, but you better be a very fast learner. The "final" for the course was that you write a robot program that interacts with a PLC program that is triggered by an HMI, and all of those programs are written by you. It isn't very advanced PLC or HMI programming, but if you have no experience in that area then I would think it will be difficult. If you have no PLC guys, nor plan to hire any, I don't know that this would be money well spent for you. From a purely robot side of things this class teaches how to set up digital and group I/O, map UOP signals, and set start method. You then use the digital and group I/O to control the robot. Not to poo-poo on Fanuc, but watching Adam Willea on Youtube, and the posts on this forum covers that very well.

    That said, having that certified course completion paper never hurts and I don't regret taking it.

    Hey Duranthas, Thank you for the comments

    I am very familiar with robotics side you mentioned above which are DI,DO,I/o mapping, UOP signal, etc.

    I am also taking couple of online course for allen bradly PLC basic stuff(not advanced course)

    Our company has a plan to make robotic cell fully automated which we need PLC on it. That's why

    I will take that course. I talked to Fanuc and they said I should take pre-course or take a test and pass it in order to enroll that course. Have you taken the test or you took pre-course for that?

    Thank you for sharing your experience.

    Hello guys.

    I am looking at Fanuc robot and plc system integration course for training.

    FANUC America

    Is anyone done that course before? I would really appreciate any review or comments about that course

    Description and table of contents look like exactly what our company needed(Since we don't have any PLC guys, only robot guys and no plan to hire any plc guys)

    Thank you

    Hey JDRyan.

    I am trying to purchase those item you listed. I wanted to know how to connect those.

    so, female end of 3pin pico cable goes to solenoid. and the other end of pico cable, there are

    3 wires, which are black blue and brown. where do I need to wire those cables?

    another question is fujikura harness adapter. it looks like one side is connected to EE on J3. and how do I connect it to the solenoid?

    I really appreciate it

    Hey, Can you please explain how to use nozzle for touch sensing?

    I also use wire for touch sensing but as you mentioned, it is not accurate.

    If we use nozzle for touch sensing, do we need to do setup something?

    Thank you

    Thanks a lot JDRyan,

    I also talked to Fanuc tech support and here is what they said, just inform anyone who needs this

    information for the future

    Wire Brake is typically controlled by air. The air solenoid is typically mounted on J3 and the EE connector RDO[1] is used to pull in the solenoid and apply the brake. Hardware for this is supplied by the torch manufacturers or the integrators.

    Just quick question, for the solenoid, what type of solenoid do we need? has to be 5/2?

    Tregaskiss said they don't supply solenoid, so We need to purchase it separately

    any information about solenoid would be helpful.

    Yes, like Scotty stated, you will see 100 percent difference with what we call here a torch tender. It cleans the nozzle and also before every program with touch sense has a wire clipper. Usually the clippers will keep it close enough it won’t hurt, but if it deviates a lot we made our own wire check system based off the wire length etc. Basically a simple research motion that will keep the robot in a loop until the correct outcome is made. The most important is the wire cutter out of the two though, wire brake is helpful but we have many that for some reason or another we had to disengage and they still work perfect. Edit: I just read your response after typing this, and realized that the wire brake was needed. Ours is activated through a universal Output if that helps? Our cells are mainly yaskawa though.

    Thank you so much, Tcgatorfan

    I also confirmed with Fanuc that we have to use RDO which is Robot Digital output for activation.

    We ordered wire brake, wire trimmer and can't wait to install and test it for better results.

    Again, I really appreciate your support. Cheers

    Thank you so much for advice, Scotty.

    Our issue is that even if we cut the wire from wire cutter, while robot travels air move in order to get weld point, wire is feeding or retracting automatically(not too much but enough to miscalculate in touch sensing). We tried to adjust tension of wire feeder as well but we couldn't keep the wire length same after we cut the wire.

    That's why we need to install wire brake on weld gun which is connected to J3 and wondering how to activate brake on/off through the teach pendant.(module A is installed inside of controller, fyi)

    I know laser sensor will give us more accuracy unfortunately, laser sensor is not our option

    But again, I really appreciate your help. Thank you

    Good afternoon everyone.

    I have fanuc 120ib/10l with rj3ib controller.

    Our company runs mig welding and we had a problem that part is shifted.

    So, we used touch-sensing and there was a progress but still can't get enough result because we don't have wire brake and cutter.

    We will buy wire cutter and install wire brake on the torch gun

    My question is

    When we install wire brake on the torch gun, how do I activate wire brake on/off with teach-pendant.

    Is there anything we need to do configuration or wiring into the controller?

    (our weld gun is tregasskiss)

    Any advice would be appreciate a lot
