How do I use this? Do I just set it once at the start of the program or before each move instruction?

I have an ABB IRB 6400R on a 14m slide. It uses an s4c controller. I am trying to mill out slots in thin material but I am finding when the robot accelerates and decelerates it seems to be causing a jolting action cause the slots to be disfigured. When in between the start and the end of the cut it is perfect.
I was wondering is there anything I can use to change the acceleration and deceleration when cutting? Is there a command I can use or would I have to change it within system parameters?

I am wondering I delete the tools I have set along with work objects as Iv created some that I no longer need.
Also does anyone know how to create the tool and work object to the actual program instead of the user so I have all the data when I save the program. Iv done it before, I just cant remember how as it was a long time ago.

One is s4c and other is s4c+

I have a system in place here with two IRB 6400 robots and a tyre machine. Each have their own emergency stop which works fine. How ever I need to add more e-stops around the perimeter of the cell and want to know how to tie all three machines together so each individual e-stop completely stops everything.

Yes this works thank you

Iv tried using both moveL and moveJ. What does ConfL\Off do?

I am trying to stack tyres 6 high and they are approx 370 mm high each. I have the program so it does a trans.z and multiplies the wheel height by the cycle count (number in stack) which then increments the height each time. It stacks the first 5 perfectly but when it comes do stacking the 6th wheel it moves across nearly reaching the approach position and comes up with the error 50080 "Position cannot be reached with the given robot configuration". I have jogged the robot to the position I am trying to reach and it goes there perfectly so I am guessing the problem is with the quadrants or something like that not being right. Is there any way around this or a better method of doing this?

Where do I enter the calibration data?
What do you mean check joint target data?
-
I have checked and the robot matches the software, Should the calibration data match the numbers in the document from global robots or the sticker on the robot?
-
We bought the robot from global robots which is a secondhand robot dealer we bought it refurbished. They supplied a document with the Calibration data but these do not match the sticker on the actual robot itself.
When I checked the calibration data last week they matched the ones in the document not on the robot sticker.
I moved the robot with joystick lock and the robot does appear to be moving in a straight line.
How do I verify the installed system matches the robot?
-
Ah yes they were checked last week and are correct.
Any idea is it the calibration causing my tcp to have a max error of 5.3?

Iv created a MoveAbsJ and axis 3 is out by -0.3 Deg axis 5 is out by 0.2 Deg and axis 6 is out by -0.7 Deg. the reason im being so fussy is because I want to use a cad soft ware to write the program for the robot so tcp needs to be accurate.
What do you mean by Calibration offsets?
-
Iv a 2400L which iv found the calibration is slightly off. Iv jogged the robot to the correct position where all the calibration marks line up correctly and then have went in and updated the counters. However when I go back to the jog window the values have not been updated to 0. They are still as they were before I updated the counters. Axis 3,5 and 6 are the ones im trying to update. The rest are set to 0 and are okay. Am I doing something wrong?

Thank you it is working now.

So for the 4th point x and z elongator should the wire be pointing straight down? Then just move straight up off it for the z elongator?
-
It was not for my most recent tcp but i have tried it in earlier attempts. However with the point i am useing I cannot position the robot to have the wire pointing in the x direction without the torch being upside down. Would this cause any problems?
-
I have checked calibration and all seems fine i have then proceeded to set the tcp as you have stated and got a mean error of 0.87 and a max error of 2.99, When I try to jog in tool coordinates it doesn't follow the wire it moves away in a different angle. Any other ideas what this could be?

I am having problems setting my tool centre point of my welding gun. I think its down to me not doing it correctly, I have a welding tip with a sharpened pin sticking out the same length as the wire would and on my table I have a sharpened round bar fixed on the table.
I am using an M98A controller. I have been using the 6 point method and i have just been bringing the robot in and touching the points at various angles and modifying each point. Is this correct? What am i to do for the points that specify X and Z do i just position the torch so it is aligned in the x position and do the same for Z?

My Robot is IRB2400L M98A With 1620mm shoulder height and 870mm upper arm length
It is for a Robotic software to create a program using cad models. The software providers have said they have contacted ABB and they say they have not got cad models for this robot as it is so old. So I thought I would ask on here to see if anyone had created one
