I will have to check it again but I was of the opinion that critical errors such as the ones in the photos could not be cleared in the way you described. Is this true?

The operator clicks acknowledge on the teach pendant to clear the error. Sometimes they have to acknowledge the error several times before the robot will start again.
The controllers have been installed in the cell since day one and it’s not easy to move.Is there a way to clear the critical errors remotely in the same way as the ackErrors system input?
More importantly, has anyone got any information on the errors?
many thanks. -

Hi all,
I’m having issues with two S4C+ 6650 that we have. The errors are:
Error 38665 Motor/Cables for joint 4 have a short circuit
Error 38664 An intermittent short circuit was detected in motor/cable for joint 4
other robot:Error 38600 incoming voltage to DC-link too low to DC link A2 in cabinet 1 single phase missing.
if any one can provide any assistance with these error, that would be great.Every time these errors occur, the tech must stop production, enter the cell and manually clear the error. While we are trying to fix the issues, can anyone tell me how to set up a remote acknowledge error for critical errors such as these so that the operator does not need to enter the cell?
Many thanks

Hi All,
Has anyone written commands to a Universal robot dashboard through TCP/IP socket from an Allen Bradley Compact logix PLC?I'm using the Modbus TCP Master Sample Application example from the rockwell website and seem to be getting connected momentarily before the connection is dropped.
Has anybody got any experience with this?
Thanks

Hi Mathew,
Thanks for the reply.
I've since found the 'unlock protective stop' command. Its odd that you can't unlock it with the EithernetIP communication.
Have you ever set up the TCP/IP socket communication between a UR dashboard and AB Compactlogix PLC?
Thanks

I have a cell with a UR10 and UR3 talking to an Allen Bradley PLC over ethernet with all communication working fine.
Is there a way to remotely enable the robot after a protective stop?
Thank you.

Hi Kwakasaki,
I am now on my 3RD robot of the same model and controller.
Got the second one up and running no bother.
However, with this one, I am getting ERROR (-1424) Current feedback error of JT 3. Amp or Power harness error.
JT3 motor looks ok and I don't see any obvious damage to the harness.
I am going to try it with the controller to robot cables from the other robots to eliminate the cable as an issue.
Any advice other than that?
Thanks in advance!

Thanks SAABoholic,
Thanks what I thought. Ill have a look for the encoder interface or extra drive when I go to view it.
Thanks again -
Hi All,
I am not familiar with flexpickers at all.
Can anyone tell me if an ABB FlexPicker IRB 340 M2000 would be equipped with conveyor tracking software/hardware options as standard?
Thank you.

Sounds like you need to check your SMB cable from the robot to the controller. Check continuity both sides of the cable to ensure its not broken. Replace it if you have a spare. Also check the cabling going to each motor. Im not familiar with the 120 but most other models have a power and smb cable going to each motor. Any time I've seen this in the past has been due to a faulty smb cable to the controller, exposed or broken smb cable on one of the motors or exhausted rev counter batteries.
is it happening in a particular position?
Sometimes it takes a while (day or two) for the new rev-counter battery to work I find.

Thanks ClauduiA,
I got it but did it slightly different.
I made the Above_Pick waypoint a variable called p100mm and then let p100mm=p[0,0,0.1,0,0,0] and then let Above_pick=addpose((Pick_pos)(p100mm))
This might be a complicated way of doing it but worked well too.
Is the relative move way easier?

Hi ClaudiuA,
Unfortunately the fault reappeared in wrist 2 this time meaning that the problem followed the joint.
Im confused though. I ran the robot for hours yesterday using all joints to see if the problem would come back but it never did. So I powered off the robot before going home and this morning the fault appeared as I was initialising the robot!

Hi All,
I have a "pick" position with an "Above_pick" position that I go to first and do a MoveL to my "pick".It is important that my "Above_Pick" is directly above my "Pick". This is easy to teach with two individual waypoints. However, if I adjust my Pick, I want my above pick position to adjust automatically.
I know in ABB you just do an offset from a defined positon and specify which direction you want to offset:
MoveJ(Offset(Pickpos,0,0,-200)
MoveL(PickPos)Thanks in advance

Thanks ClaudiuA
Those are exactly the suggestions that UR gave.
However, I swapped wrist 1 and 2 and exchanged IDs and its been working fine since.
I wont be surprised if the fault returns in wrist 2 but it seems fine for now.
Thanks again

Hi all,
I am currently working on a robot for a client that was repaired by UR in the last year. One of the joints was replaced by UR but hasn't run since as it is a spare unit and now I am trying to run the robot with a different controller than the original. It boots up fine and initializes but when I move the robot I get the following error:Wrist 1 : C75A1: Joint encoder error: Invalid decode: Read head misalignment, ring damaged or external magnetic field present.
Can anyone please point me in the right direction to fix this?
Thank you in advance.

Hi All,
I have been toying around with a project where you use coordinates generated by a slicer or CAD-CAM software to control a robot for Machining and 3D Printing.
I know this is becoming more common but I wanted to see if I could do it myself.
I had tried it on an ABB robot (Of which I am well experienced) and it worked quite well. However, I no longer have access to an ABB robot and all I have is a Kawasaki UX120 robot with a c series controller of which I have little to no experience.
With ABB, I was able to use RobotStudio to take the coordinates generated by the CAD-CAM software and put them into a rapid program, save the program on a USB or Floppy (depending on the controller) and open it up in the robot an it worked fine.
Basically, my question is, can I do the same with a Kawasaki? If so, how?
Thanks in advance!

Hi All,
I am relatively new to UR and I am trying to change the initial position that the robot must be moved to before starting auto.
I always thought that this was the first position in the program but in this case it is making me move it to the second position in the program.
The first couple of lines of my program are something like this:
If PickMC=0 and PlaceMC=0 and PickNewPart=0 then
MoveJ pHome
endifIf PickNewPart=1 then
MoveJ pOvrPickNewPart <----------its making me move to this position??
.
.
.
.
.etcAlso Please not that all my variable are equal to 0 on starting the program and then after moving to pHome the operator is asked to enter the variables.
Many Thanks in advance!
