Nation What does this option do? I tried googling to find more info, but could not get any good results. This option sounds very useful, but wanted to get a better understanding of how it works? Thanks,

Good afternoon, does any one recommend any classes offered to learn how to program, install / set-up Fanuc robot controllers (such as R30iB or R30iC)? I'm sure Fanuc has some, but maybe a 3rd party offer good ones as well? Or perhaps even colleges that offer degrees in robot automation? Thanks,

Assuming you are using R30iA or R30iB, please check connection between EAS1-EAS11 and EAS2-EAS21 (usually located on a board inside the panel on door itself). This should be a closed loop. You can check this by placing a jumper cable from EAS1-EAS11 and another jumper from EAS2-EAS21. If this fixes your safety gate issue, then you have issue with your safety lock / device. If this does not fix issue, you may have issue with the board or some other cable.
Your issue may be similar to srvo-004 fence open fault, here is troubleshooting on this fault from manual:
(4) SRVO-004 Fence open
(Explanation) In the automatic operation mode, the safety fence contact connected to EAS1-EAS11
or EAS2-EAS21 of TBOP4 is open.
(Action 1) When a safety fence is connected, close the safety fence.
(Action 2) Check the cables and switches connected between EAS1 and EAS11 and between
EAS2 and EAS21 of the terminal block TBOP4 on the panel board.
(Action 3) If the safety fence signal is not used, make a connection between EAS1 and EAS11
and between EAS2 and EAS21 of the terminal block TBOP4 on the panel board.
(Action 4) Check the mode switch. If trouble is found, replace the mode switch.
(Action 5) Replace the panel board.

IFM AL1422. Not really designed for panel mount, but they work. You may need more than one, but the I/O link ability may save you some IO. I've used these a bunch lately and they are super simple to setup over IFM's free lr device software.
If you've never used an IO link sensor you'll be in for a treat.😁
How did you make that work without a PLC? If you plug Ethernet cable from IFM device into robot, how do you know the configuration / racks assignments? I have used this IFM devices as well (works great), but mine is communicating with PLC via Ethernet; then PLC communicates to robot via Ethernet.

I know for IMSTP, SFSPD, and Enable, all these 3 signals need to be "on" for robot to run. If robot does not see these signals on, it will not run. I believe they stand for immediate stop, safe speed, and enable. I have these tied to my plc and use logic to turn off. I have DIs mapped to the UIs.
Start is starting the robot program. I'm unsure what UI17 is, but looking on a website, it stands for program number select.
The UO's are just feedback from the robot to your plc or controls device. CMD enable and system ready mean robot should be good to go. ACK is probably acknowledging some request or button hit perhaps?
This website has some good info on some of these UI/UO towards the bottom of the page: https://www.onerobotics.com/posts/2016/sta…0this%20is%20ON.

When is the last time the robots were greased? Maybe you lost some grease in that joint and needs replenishing.
Does this fault occur in a certain position or is it random? If it's in a specific position, maybe it's going too fast, and you can slow the approach speed down also.
Or as CSaunders mentioned, check the mechanical components. I found once we had low grease in a joint, and some metal shavings began appearing in the grease. We had to replace gear and re-grease robot to get the dirtiness out.

Were you megging from one phase to ground, or between phases?
It should be close to 0 ohms between phases, and then OL between one phase and ground if I remember correctly.
Also, please check out this other post, has some good info from Skooter: fanuc error (servo-156 IPMAL alarm (G:1 A:2) )

One thing I noticed on my own robot controller (R30iA) is that it won't read anything greater than 2 GB flash drive, I can only use 2 GBs or less on all my robots. I think it's supposed to be like this, but someone else can confirm. And Welcome to the forum
-
You should take an image backup, all of the above backup, and grab the master count data from the variables section, and hide the flash drive so no one else can sabotage the robot.
-
Bump, anyone know where this is located? Seems like great info to keep an eye on the robots. Or maybe this is not on R30iA or iBs?
-
Many thanks for the info guys, I'm getting a better understanding of these robots on this site!
-
I still do not understand what the difference is between image backup and All of the above. Of course, it's best to back up everything, but if I just make a small teach point modification, what is the bare minimum I should backup?
If my robot loses all memory, will an all of the above backup suffice? I think it should, because it has all the TP programs and all the master count data, correct?
-
Thanks for the help guys, I appreciate it!
Also, quick and easy question, if I make a change to a point on these robots, is doing an "all of the above" backup sufficient or do I need to do a full image? Does a full image backup include all the tp programs within it?

Good afternoon all, hope everyone is doing well. I want to change the IP address on the robot and the plc it's communicating with, so when I go to the "I/o Ethernet IP" page and hit "config", it is showing me the ip address of my plc, but I cannot change it since it's read only.
When I hit 'next', I see "exp-msg" and I see the correct IP address there for my PLC. Is this the correct place to change the IP address of PLC? Any other steps required?
Furthermore, where can I find the robot ip address and how can I change that?
Thanks!!!

Thanks Skooter, that's really good info too, now I understand it better !

Sounds good, thanks man!

Is it safe to replace the SRAM + DRAM card with power on? Both sit on the main CPU A Board. With controller power on and backup battery plugged in, If I pull out the entire Main CPU A board, and swap out the SRAM and DRAM cards, hypothetically I should not lose anything, correct?
-
So if my SRAM memory card goes bad, do I have to re-upload all the TP and image backup files? What about DRAM and FROM?
-
Good morning all, I have a FANUC R30iA controller and wanted to understand some of my spare parts. I have one SRAM card (A05B-2500-H064) and one DRAM card (a05B-2500-H021), and I wanted some one to explain the purpose of these two cards inside my controller? This is for my own general understanding of the machine parts. Thank you!

Just to follow up with everyone, the issue with the above fault was a bad RP1 cable (going from back of robot into the controller). We also replaced the ground wire as well. Then, the problem went away.
Thanks for all the information, especially to HawkME !
