as you can see address you are trying to use is conflicting with reserved ranges (used internally). You cannot assign address to KLI that conflicts with those ranges.

changing internal addresses on KUKA is not documented. you can contact KUKA but it would be a long shot. what is this network address supposed to be used for? it may be easier to just add router.

Hello, i think they want to use this type of address because they may want to access to some data of the entire machine by having it on the network that they want, honestly i don't know more than that, we have been changing IP address of all the rest of the devices to 172.16.115.xxx, and the Robots are the only remaining.

So your advice is contacting KUKA for this? I think this customer can put a bit of pressure on the question, since they are a really big company, so maybe the time of response will be shorter.

Hello guys,

I am having some issues changing an IP address of a Kuka Robot (KRC4 and KR 470-2 PA), running on ethernet communication.

- The robot currently has this IP: 192.168.1.54

- The customer requires an IP change, they want to use this, IP: 172.16.115.254, Gateway: 172.16.115.1, Subnet mask: 255.255.255.0

When i try to change the IP with the Teach pendandt, i get the "IP Address conflict" message. I tried doing this with the Robot disconnected and connected from the network with no succeed.

I attached some pictures of some IP addresses that are on the Robot.

Thanks!

Hey guys thanks for the help!, i really appreciate all this information, is like gold to me :D, hopefully i will be powering up those robots this week, so i hope everything goes fine !

Thanks!

1. yes. you can connect robot to some controller and master it. mastering info stays on the robot, not controller. so after this you can power down, disconnect them, transport them, connect them together (or to other controller) and everything will be fine. robot will lose mastering if moved by force (without using controller). an example of this is manually driving robot in emergency using manual release wrench (12mm socket, connects to end of the motor).

2. you can check mastering logs (C:\LRC\ROBOTER\LOG\mastery.log). mastering is selected based on application and required accuracy. if your robot is HA or ABS variant, you do want to use the mastering with offset. if you have a standard robot and variety of payloads or tool changer, you may also want to do the same. if your robot only has fixed tool(s) and always handles same or similar payload, standard mastering is fine.

3. yes and sometimes you have no choice but for sake of repeatability it is better to bring all axes to premastering position, then master them all. that way you get the smallest variance in readings when using check mastering.

Thanks a lot for the help!, regarding to question 1, so doesn't really matter if i plug the robot into a different controller? it will be not a "position mismatch" regarding to the previous robot that was connected there?, how does it keep the information of the servos if the robot does not have batteries?

Hello guys, i am a little bit new regarding with KUKA Robots, and currently i am on a proyect where i need to calibrate some robots that have been without power for more than 1.5 year.

The model of the robots are :

KUKA KR 470-2PA, with KRC4 controller.

I have been asked for several questions regarding to the mastering (for the customer), and i just have some information that i found on the manuals about mastering. Eventhough this, i still have some questions.

1) Can i master a new Robot for example in the shop, and then disconnect the robot, and place the robot on the working area, and connect it to the same controller and still keep the mastering? I know that Fanuc robots have batteries on the robot, but as far i as know, batteries on kuka are located on the Controller, so, i will lost mastering if i unplug the robot from the Controller, and then connect it again?

2) The Robots are handling several payloads, depending of the process, some robots handle 150 Kg payload + 50 Kg tooling, others handle 30 Kg payload + 50 Kg tooling, and the others 200 Kg + 50 Kg tooling. The Robots were already tested on the shop, moving the payloads, but i don't know if they were calibrated with the "offset" or "load compensation" there. So my question is, if the Robots need mastering, do i need to calibrate with the "load compensation", "offset" option? or just with the regular mastering should be ok?, should my first mastering be without the tooling? Then the tooling? then the tooling with load?

3) Can i master the robots regardless of the position of the other axis? For example, calibrate axis 1, then move the Robot in A1 to have enough space to calibrate axis 2, and so on? Or all axes needs to be on the pre-mastering position to be calibrated?

Sorry it was a long text, hope you guys can give some advices.

Cheers!

SOLVED!!! I checked all the connectors inside the controller, i disconnected and connected one by one, i turned on the robot again and the problem was gone, thanks to everyone for the help, was very usefull all the advices.

I found the cable in the manual, it is the cable ¨CRM2A-2¨ *HOLD - Temporary stop, i will check this connection now

The only present fault it is the hold button, in fact, there is no ¨Fault¨ present, because the fault light is it turned off. Did you know which cable could be (inside de the controller) the responsable of the Hold signal? I will start to check every cable inside but they are a lot.

Here is a picture

Thanks i already made the replacement of that module, but the problem still there, i dont know what else to check

Hello, i have a problem with a Fanuc robot S-420 iF , with a RJ2 Controller, first, the robot was working completly fine, next day didnt even turn on the controller, i dont know if here happened a voltage drop on the lines, i checked voltages, everything, so i decided to replace the power supply unit (i had a replacement here). After that the robot turn on normally, but i have this issue with the hold function, because all the time the led state of the pendant ¨HOLD¨ it is turned on, so i can´t perform a cycle start to make the robot work, if i put it in Manual mode (T2) , the Hold light stills on, and if i try to jog the robot, the pendant shows this two errors:

- JOG-005 CAN NOT CLEAR HOLD FLAG
- SYST-001 HOLD BUTTON IS BEING PRESSED

I checked the HOLD button from the operator panel, it is working fine, closing and opening the contacts, and disabled the UI signals on the robot (because i am using this signals from a PLC to the robot), but even doing this i still have this message.

I have changed:

- Power supply unit
- Teach pendant
- Teach pendant cable
- Operator panel board

If anyone could give me an advise, will be great, thank you guys.

Hi, i have the roboguide 6.40, i need to backup some files from the roboguide to the PCMCIA card, i have and old notebook with PCMCIA reader so i can explore the card like a disk, but i can't see it in the roboguide program, i select it with "Set device-Mem Card(MC:), and i hit "backup-all of above", the program says "Total 58 files saved", but i go "My computer-Disk F: (PCMCIA)"and it's empty

What i'm doing wrong? the roboguide program needs some special configuration to see the PCMCIA?
Thanks
