Hey guys, just wanted to clarify one thing. If I unplug the RM1 and RP1 cable from my robot and replug in, will this lose any memory from the encoder? I believe unplugging the RP1 will lose all encoder info and I'll have to remaster/cal the robot, but the RM1 cable is just high voltage power lines to all the motors, correct? Thanks and have a great weekend!

Good morning all, hope everyone is doing well.
I have both R30iA and R30iB Fanuc controllers, and interested in getting a signal back from the robot if it waits over 90 seconds at any line of code. Do I have to use a digital output for this along with background programming or is there a signal I can grab somewhere from inside the controller? Looking for a 24VDC signal from the robot.
Thanks,

Does unplugging teach pendant with power on actually do damage? I thought our guys may have done these hot swaps without too much problem. Usually there is a fuse you can swap on the board where teach pendant plugs up. You may have to swap the board out also. What is the exact fault you are getting? Make sure that the estop isn't pressed in on the new teach pendant, sometimes it's already pressed in once installed.
Best thing to do as well would be to call Fanuc Robotics group directly and get there input also.

Would having Robot door on R-30iA or R-30iB cause this fault? I have had the robot cabinet door open but the robot still runs in auto?

If you have switch on robot controller in "T1 mode" and teach pendant switch to "on", then you can hold dead man switch and shift key to move robot around using the blue joint buttons on the left.
If robot controller switch is in "auto" and teach pendant switch is "off", then you can hit reset and cycle start to run whichever program you have selected on your teach pendant, usually "main".

Could someone explain the difference between controlled, cold, and hot start, and when to use any of these? Also, wouldn't a normal bootup be considered a controlled start perhaps?
Thanks,

Sounds good, I'll get some ordered. Thanks!

Does anyone know the part # for these grease fittings? I need to order some, but Fanuc tech support seems really backed up today. I have the same robot, M710iC/50, and need to replace the fittings on the robot itself on Joint 2, but assuming all joints have the same fitting?
Thanks,

I had a friend take a math test, and calculator needed to be in degrees, but he left it all in Radians. Got everything wrong! Haha luckily teacher was cool enough to convert to degrees and give him good grade.

I'm sure Youtube has some good tutorials for you to find and study various robot program techniques, tips, and tricks?

I couldn't find anything when I googled "SPOT-480 warning on my RJ3iB", you may want to call Fanuc?

Your air lines may be good, but check power going into solenoid valve. You should see some form of a light turn on (on the valve itself) whenever you activate the RO1 or RO2. If this light is not coming on, then most likely a wiring issue to the valves. Not sure how your i/o is wired, but if you are using fanuc i/o block, you should be able to measure 24vdc from the output of the cards going into the valve. Or if you are using PLC, then the same applies, you should see 24vdc from output of card going into valves.
I'm assuming you were not using these valves with the welding head and only recently added them?

What's USB size? I can never get anything more than 2 GB to work, so maybe try smaller memory on flash drive. I'm very surprised the MC card didn't work. Did you try to get answers from Fanuc directly? They would definitely point you in the right direction.

I don't see the issue? 100% speed means 100% productivity!!!

I don't get how the witness marks are unreliable though? My fanuc robots don't have any vision, but whenever we master, we always use the witness marks and that gets us extremely close usually. May have to touch up a point or to. Doesn't make sense why Fanuc would have the witness marks off by a degree or two, that would definitely ruin the entire mastering process?
-
Nation Any update on how it works? I don't know any Python, so to me, it seems like a huge learning curve, coming from Fanuc. Any major similarities or differences you found?

TomFoolious Do you have to move the duplicate robot into the same position as the original robot to get all the teach points to match up? Couldn't you just take an image file from old robot and upload into the newer robot, that way all the master data points would be the same?
-
Could you share a video of what your robot is doing, or perhaps an equivalent Youtube video. Would be great to see, never seen a robot do what you are saying in action before.
Thanks,

Are robots communicating to plc via ethernet or hard-wired signals? Either way, if you can get them to communicate a few signals b/w them, you may could get it to work. I only have two robots in one cell, so you may have difficulty with extra robots. Get the robots to look for the correct DI's and include what Erik mentioned also with the heartbeat signal so the robots know that comms are good b/w each other.
It may take some extra i/o for you, so if that option isn't available, then DCS or space may be the better alternative as mentioned.
-
If you have robots in same cell right next to each other, and they have communication b/w them, then you can enable a DO saying "robot in area, do not allow other robots to enter". Then all other robots if they want to enter that area, then must wait for the equivalent DI to become false. Once it's false, then other robot can enter the area and turn on it's own DO.
This method should work if you don't have any of DCS options available.
